What is 1.4373 stainless steel?

1.4373 stainless steel, also known as X12CrMnNiN18-9-5 and AISI 202, is an austenitic stainless steel. It is a nitrogen-enhanced alloy, meaning it contains a higher nitrogen content than standard grades. This composition gives it good corrosion resistance, high strength, and excellent formability.

Is 202 stainless steel corrosion-resistant?

Yes, 202 stainless steel has good corrosion resistance but is not as resistant as 304 stainless steel. It performs well in most environments, including indoor, mild outdoor, and some food-related applications. However, in chloride-rich or highly corrosive environments, 304 or 316 may be more suitable.

 

Can 202 stainless steel be welded?

Yes, 202 stainless steel can be welded using standard welding techniques such as MIG, TIG, and stick welding. However, due to its lower nickel content, it may require special considerations during the welding process, such as using the appropriate filler material to prevent issues like cracking or heat-affected zone sensitization.

 

What are the main applications of 202 stainless steel?

202 stainless steel is commonly used in architectural and decorative applications, as well as in home appliances, automotive parts, and food processing equipment. It's ideal for applications where moderate corrosion resistance and high strength are required at a lower cost compared to 304 stainless steel.

 

What is the difference between 202 and 304 stainless steel?
The main difference between 202 and 304 stainless steel is the nickel content. 304 stainless steel contains 8-10.5% nickel, while 202 stainless steel has only 4-6% nickel. As a result, 304 offers better corrosion resistance and is more versatile, but 202 is a more cost-effective option for moderate environments.

 

202 stainless steel is a cost-effective alternative to 304 stainless steel, offering good corrosion resistance, strength, and durability in moderate-duty applications. However, its corrosion resistance isn't as good as 304 or 316 stainless steel.
