Distinction between Stainless Steel and Aluminium.

Stainless Steel and Aluminium are the 2 metals which are used in day to day life. They are like an inseparable element from utensils in the kitchen to screw in cars you can see it everywhere. Stainless steel and Aluminum are similar in appearance, but they have distinct characteristics that make them unique. In this article, we will discuss the characteristics which make them different from each other.

1.      Strength & Weight
Stainless steel and Aluminum are both strong materials, but steel is stronger. However, aluminum is almost 1/3rd of the weight of steel, it has a higher strength to weight ratio. When both strength and lightness and are needed, aluminum is an ideal choice. Hence aircraft and bodies of automobiles are made from aluminum.

2.      Cost
Stainless Steel is expensive compared to Aluminium; however, both can be purchased at affordable prices and both are highly recyclable environmentally-efficient materials.

3.      Corrosion Resistance
Both aluminum and stainless steel have corrosion resistant properties, however stainless has an edge because it is partly manufactured from chromium. The chromium in stainless steel offers it what is primarily an invisible shield against corrosion. when stainless steel will rust, this protective layer takes the strength of it. Once the rust is scrubbed away, the chromium shield simply renews itself.

Aluminum doesn't rust a similar manner steel does, however, it does corrode. aluminum also has a defend – a thin layer of aluminum oxide – that protects it from rust. However, this shield doesn't protect the metal from alternative types of corrosion.

4.      Conductivity
Stainless steel is a bad conductor compared Aluminum. Aluminum exceeds stainless steel in both electrical and thermal conductivity. The reason why aluminum used for things like cars, air conditioning units and even high-voltage power lines.

5.      Composition
Stainless steel is an alloy made up of iron, nickel, manganese, copper, and between 10 to 30 percent chromium oxides. Because it does not allow liquid or air to pass through it the resistance to corrosion is increased. 

Aluminum is a natural element and has high oxidation and corrosion resistance due to its passivation. 

When aluminum is oxidized, its surface will turn white and sometimes pit. Aluminum may corrode rapidly with catastrophic results, in extremely acidic or basic environments.


6.      Malleability.
 Aluminum is more malleable and elastic, making it easier to cut and form. This quality makes it great for projects like cooking pots and pans and tools. 

Stainless steel can be more difficult to work with due to its resistance to abrasion and forming, which means it is ideal for heftier projects like roofing, major appliances, computers, skyscrapers, and bridges. 


7.      Spark-ability. 
If you want to know the immediate difference between the two hard metals, subject each to a grinder. Stainless steel will give off sparks, while aluminum will not.

 While each material has a specific job both aluminum and stainless steel are important metals.

Everything you need to know about ball valves

Ball valves are one of the far and widely been forms of transportation used across the world including pipelines. You might have very well seen that the pipelines are used to transport huge gallons of gas and liquid products quite efficiently. To stay effectively, the pipelines necessitate a special piece of the element so as to regulate the flow of gas and liquid in the pipe which is termed as ball valves. Ball valves are similar to mechanical switches and have the ability to turn pipeline off and on, in another word they act as a controlling mechanism for the precise flow of product through the pipelines.  Everything you need to know about ball valves is briefly explained in this article.

What are the valves?
Valves are similar to a mechanical device which is used to either full or partially block the pipeline. One such example of the valve is faucet which gets easily turned off and on just by activating or sliding it that eventually allow water to flow through it. The leading manufacturer and suppliers like the citizen Metals make the utmost high quality of ball valves that makes it reliable to use it for performing industrial as well as commercial operations. Faucet generally contains a ball valve.
The ball valves are prominently been used to regulate not only gases but also liquids and fit precisely in any mechanism or machine that is used to transport product via a pipeline.

How a valve gets made?
The ball valves are generally made using the stainless steel. The inner part and the outer part are called body and seat respectively. The outer part frequently contains a metal casing or plastic casing so as to provide a complete sealing and the inner part get fit into that seal that ultimately let the valve close. It is just like the manual lever and another type of mechanism used to control the product inside a pipeline.



According to best valve manufacturer, the most crucial aspect of the ball valve is that the switching off of the valve blocks off even the smallest of the liquid and gas amount and does not allow it to escape. That’s why top manufacturer makes the ball valve keeping in mind that the valve gets sealed completely and perfectly to keep all of the gases and liquid inside.

Working on a ball valve:
Ball valves are all durable and performing after lots of cycles and are reliable too. It gets open when the hole of the ball is in alignment with the flow of product and it gets closed when pivoted at 90 degrees by a handle. The valve handle lies horizontally with the flow arrangement and is at a 90-degree angle to the closed visual corroboration.

Since they are made of metal as well as plastic it can withstand a temperature of about 1000 bar which is around 752 degrees F depending on the material and design. The size of the ball valve is around 0.2-48 inches and the insulation on tape prevents it from damage.

You can buy the ball valve at an affordable price from the reliable online store.

What is perforated stainless steel?

The perforated stainless steel metals are generally a form of metal sheets, which gets stamped and punched using an advanced quality machine so as to create an outline of holes. They are also widely known as perforated plates, perforated sheets, or performed screens that are commonly manufactured using cold rolled steel, stainless steel, aluminum, and many more materials.

The perforated stainless steel first gets developed around 150 years back for top class industries as means of straining coals. Initially, the perforated procedures are inefficient and involve a good number of manual labors for punching individual holes patterns into the metal sheet. With the passage of time and technological advancement, the procedure got improved via the use of machinery exploiting into punching needles in specific patterns.

How perforated steel gets made?
The manufacturing procedure for perforated steel gets started with a metal sheet. The metal sheet is generally, flat and thin, and can be bend and cut into various shapes. The thickness of metal sheet gets specified with gauges; the sheet gets thinner with the increase in gauge number. The metal sheet is measured in mm across the world.

The most common technique used in perforation of metal is a rotary pinned roller. It is basically a large cylinder with pointed needles that are sharp on the outer side so as to punch holes into sheets. When the sheet run over the perforated roller, it rotates repeatedly, thereby punching holes while pressing sheet.  The roller needles, which are capable of producing holes of various sizes when heated simultaneously, get melt in forms around the perforation.

Another method is known as “die and punch” method, during the process the sheet gets repeatedly pressed with needles onto metal thereby punching holes in the sheet. The residual pieces get shear off after punching and the face gets smoother. This method is considered efficient and it can perforate larger surfaced of metal sheets very quickly.



The most advanced and reliable method available in the market is laser perforation used by the Anil Metals. The procedure is really sophisticated and accurate but it also an expensive one. The laser perforation offers results similar to that of rotary pinned perforation, maintains a higher degree of consistency, and can control over pattern and hole sizes with hot needles.

Benefits:
Perforated stainless steel sheets are widely and broadly use in contemporary architecture as it lends creative and unique designing techniques. Some of the practical benefits are-

Climate control and sun protection- The perforated sheets are exceptional at offering space with good airflow and they are frequently used as screens from sun protection that require ventilation in rooms. They appear to be an utmost designed element with permeable nature allowing free movement of fresh air resulting in energy saving on air conditioning, ventilation, and heating.

Noise reduction- The perforated stainless steel sheet is used as a noise reduction material for roofing and wall systems. They are capable of limiting the unpleasant effect of noise in the noisy environment.

Balustrade screening panels- Perforated stainless steel are used as a stairway, balustrade screen and balconies panels that offer protection.


You can buy it from the official store of a trusted and reliable company.

Flanges: Applications, Types and Flange Ratings

A flange is said to be a strategy for connecting valves, pipes as well as pumps to frame a piping system.  With this, it provides easy access to examination, cleaning, and adjustment. The flanges are generally screwed or welded and the joints of it are manufactured by bolting together two flanges along with the gasket between them in order to provide a seal. Also, the flanges are forged as well as a thrown ring of steel made to interface segments of join pipe or pipe to the pressure weight pump or vessel.

This is connected to each other by darting and connected to the piping framework by threading or welding. Following are the fundamental kinds of flanges such as threaded, lap joint, and socket weld, orifice as well as weld neck. It is made to the following pressure ratings such as 400lb, 1500lb, 300lb, 150lb and 2500lb.

The most extensively identified facings machined on a flange such as-
  1. Raised face, 1/16 inch for 300lb or 150lb and ¼ inch for heavier.
  2. Flat face is for 3000lb or 150.
  3. Ring Type Joint Flanges could be applied to the entire pressure eight ratings.

We at, Metal Yard is one of the leading flanges supplier or makers in India. And even as a pioneering maker of flanges, we provide flanges in every corner of the globe. We handle flanges generated through various grade and evaluations of materials. We can provide the flanges in customized options to the customers around the world.

Here are some different kinds of flanges described such as-
Tongue flange/groove flange- the grooved flange is continuously accompanied along with the tongue flange. In this blend, a flange holds a machined raised ring known as tongue and other different machine groove depression known as a groove.

Slip-on Raised Face Flanges - this is a pipe flange and its name says slip over the pipe. Well, it is set up by welding at the top, with the addition of base side on the flange. It helps in neglecting leakage or spillage and offer quality strength to the association.

Blind Raised Face Flanges- a blind flange is also known as blanking flange that is used as a segment of sealing or fixing an end of the piping framework. It is used being a portion of high-pressure weight application in order to ban the line of fluids or gases from a single end.

High hub blind flange- this flange is equal to the general type of flanges. And it seems like a simple round plate with no focal hold. It is mostly used in the application in which close tolerance is vital.

Expander flange- such kind of flange is the mixture of a reducer and weld neck pipe.  Also, the non-flanged end of this flange is bigger than to the flange end. It is used where the need of changing the size of pipe run.

Types and Uses of Copper Nickel Fasteners

Do you know what fasteners are? A fastener is a hardware that is used to mechanically fix or join two objects together. Fasteners create non-permanent joints so that joined parts can be separated easily without damage. In the case of permanent joints, welding is used instead of using fasteners. The fastener is a very common and widely used tool in any industry whether commercial or for domestic purpose. Thus, they are available in different categories such as carbon steel fasteners, stainless steel, and alloy steel. These categories are further divided by the grade where each grade is used in either different or common purpose depending upon the type of application.

The common fastener used in most of the applications is a Copper Nickel 70/30 Fasteners. Such fastener is made of copper and nickel alloy that provides strength due to the presence of elements such as manganese and iron. These elements are responsible for adding strength to the fasteners.

Types and its uses:
There are different types of fasteners available which are used according to the purpose. Following are the different types:
  •  Anchor bolt
  • Brass fastenerCaptive fastener
  • Clevis fastener
  • Snap fastener
  • Threaded fastener
  • Hook and loop fastener and more.



These were few of its types, many more are there. Every fastener is made of common materials used for manufacturing however in some cases plating or coatings is applied to enhance the corrosion resistance properties of the fasteners. Coating of chrome, zinc and other material may be applied to improve its characteristics and life.

However, before using the fasteners in any industry one should know the specifics so that proper material is used in the desired application. One should consider the following factors while choosing a fastener.

  • Accessibility- the fastener of a particular material should be accessible and easily available in the market
  • Environment- fastener should give better performance in any adverse atmospheric conditions such as high temperature and long water exposure.
  • Installation process- they should be easy to use
  • Reusability- the life period of fastener should be long so that they can reuse after the completion of applications.
  • Materials to be joined- the two objects or parts being joined together should be kept in mind and according to them, the fastener should be selected.


The copper-nickel fastener is suitable and withstands all these factors thus they are used in many applications. The copper-nickel fastener is used in marine applications where resistance to corrosion caused by seawater is required. It is also used due to its excellent properties such as good fabricability and low macro fouling rates. Copper Nickel 90/10 Fasteners have high iron content that gives it resistance against impingement attack. They are also good at giving resistance against cracking. Such properties make it suitable to be used in adverse conditions. The increased copper content does not change the color of a fastener and it gives it silver look.

A copper-nickel fastener is used in various industries such as:
  • mint industry
  • desalination industry
  • armaments industry
  • marine engineering
  • electrical industries
  • chemical and petrochemical industries, etc.

What are the grades of bolt and nuts?

Alloy steel, stainless steel, silicon bronze, brasses are some of the materials are used to manufacture bolts and nuts. The combination of treatment, material, coating, and hardening are very much essential in order to get a determined strength, which is then used for the appropriate application. The article also entails types of grades of nuts and bolts available in the market. Moreover, you can visit the online store easily and grab the desired grade of bolt and nuts at a reasonable market price.

Bolts:
Generally, bolts are considered larger than a screw, which is used in numerous industrial and commercial applications particularly load-carrying capability requirements. Depending on the sort of bolt, the uses may comprise wood to metal, wood to wood, metal to metal and object to metal and wood. Some bolts have a smaller screw or similar screw counterparts- like lag bolts that are used as heavy duty screws. The various types of Bolts include Hex Bolts, Stud Bolts, Anchor Bolts, Eye Bolts, and Heavy Hex Bolts, etc.

ASTM A490 and ASTM A325 are two basic standard structural bolts. If you take a glance at the mechanical need you will see that SAE J429 and ASTM A325 grade 5 looks identical. The same is true for SAE J429 and ASTM A490 grade 8. So, it can be used when ASTM A325 gets specified. 

The reasons will answer it precisely-
  • A490 and A325 bolts are a manufacturer with heavy hex configuration, Grade 8 and 5 bolts are manufactured with standard hex screw configuration. It provides a wider bearing surface that gets distrusted load over bearing surface.
  • The grip length on A490 and A325 bolts get designed compared specifically to standard hex bolt or cap screw. Some changes can be created to get a stronger and powerful tensile connectivity and it can also be changed in thread lengths also.

Nuts-
Nuts are employed with threaded rods, screw, bolts, anchor- and other has machined screw threads so as to fasten anything. Different kinds of nuts get utilized in different application broadly and are categories as locking and plain. Basically, they are sleeve or block having inner threading designs to assemble it with an outer thread on screw, bolts and other parts. It serves as adjusting means, transmitting power with high mechanical benefits, fastening means and transmitting motions.

Some of the notable grades of Heavy Hex Nuts are ASTM A536-Grade A heavy hex, ASTM A563- Grade 0, ASTM A563 Grade A, ASTM A563 Grade C heavy hex, ASTM A563 Grade DH heavy hex, ASTM A194 Grade 2H Heavy hex, ASTM A194 Grade 8 Heavy hex.

The ASTM standard arrangement for stainless steel and alloy-steel bolts are broadly been used in elevated temperature as well as high-pressure environments including special-purpose applications. The ASTM nuts and bolts are available in different size, length and range of grades to meet service conditions, high-temperature requirements, design and mechanical properties that client needs.
The high pressure and high-temperature performance of nuts and bolts make it suitable to work well in various applications such as chemical and petroleum industries also in valves, flanges, vessels, and fittings.
