Comparison between Stainless Steel 310 and stainless steel 202 pipe

Different industrial processes require different kinds of industrial environments and hence the equipment used in them also differs in qualities. We here discuss the two commonly used stainless steel alloys viz. 310 and 202 and the usage of pipes made from them.

Chemical composition of stainless steel 310 alloy and pipe

The versatile 302 alloy is formed by combining different metals and elements. It has 24 to 26 % of chromium, 19 to 22 % of nickel, 2% of manganese, 1.5% of silicon, 0.25 % of carbon, 0.045% of phosphorus and 0.03% of sulfur.

Chemical composition of stainless steel 202 alloy and pipe

The alloy contains 16 to 18% chromium, 6.8 to 8.5 manganese, 2 to 5% of manganese and 0 to 0.255 of nitrogen. Carbon and other metals/elements are added for balancing.

Usage difference

The stainless steel alloy 310 offers extreme resistance to oxidation and its scaling. It also has high strength even at higher and elevated temperatures. It is also extremely ductile and various shapes can be made out of it. The stainless steel 310 pipe offers continuous service that can withstand temperatures up-to 1140 degree Celsius. Their service quality decreases in the presence of sulfur gas. It has high amounts of chromium and hence provides for versatile properties of corrosion resistance. It can resist pittance, crevice, and general corrosions with ease and can also resist marine corrosion caused by high chloride content of sea water.

Stainless steel 202 pipe offers adequate corrosion resistance and strength but is more prone to cracking because of its higher carbon content. The stainless steel 200 series alloy has lower nickel content than the 300 series and is hence is less costly. It has a high carbon content that can result in cracking. In other aspects like fabricability, corrosion resistance, etc. they are similar to 300 series. Still 300 series stainless and 310 stainless steel pipes provide more corrosion resistance than their 202 counterparts.

Applications

Pipes, tubes, sheets, etc. of the stainless steel 310 alloy are used in industries like gas, oil, petrochemical and in chemical processes. It is typically used in heat exchangers, furnace parts and in jigs and baskets providing heat treatment.

The 202 alloy pipes, tubes, etc. are used in industries like pharmaceutical, petroleum, aviation, food. Heat exchangers, fluid transport, etc. The 202 series alloy and its pipes can replace the 300 series in places where there is low corrosion. Its most typical application is in low corrosion conditions. It is often used in cookware, bins, furniture, Industrial strapping, rolling stock of railways, equipment for coal handling, etc.

Performance

The functioning and working of 200 and 300 series alloys is similar in industrial conditions that do not have much corrosion. They also perform on-par when used indoors.

Hence, it can be concluded that the 310 pipes provide for high corrosion resistance while 202 pipes have better strength. They are used in specific industrial climates that have different wants. While the stainless steel 310 pipe can provide for better corrosion resist in marine environments, the 202 pipes have the better strength that is much required in many other industrial processes.
