Why Choose ASTM A240/ASME SA240 UNS S20200 Stainless Steel 202 Sheet?

 

ASTM A240/ASME SA240 UNS S20200, commonly known as 202 stainless steel, is an austenitic stainless steel with 17.0-19.0% chromium, 4.0-6.0% nickel, and 7.5-10.0% manganese. It is designed as a cost-effective alternative to higher-nickel grades like sa 240/a 240 uns s30400, offering good corrosion resistance in mild environments, excellent formability, and moderate strength. The high manganese and nitrogen content maintain the austenitic structure while reducing costs, making it ideal for applications in architectural, appliance, and general-purpose industries.

The ASTM A240/ASME SA240 UNS S20200 stainless steel 202 sheet provides slightly better corrosion resistance and strength than sa 240/a 240 uns s20100 due to its higher nickel and chromium content, but it is less suited for aggressive environments compared to sa 240/a 240 uns s32550. Its affordability and formability make it a preferred choice for decorative and non-aggressive environments.

Key benefits of ASTM A240/ASME SA240 UNS S20200 stainless steel 202 sheet include:

• Cost-Effective: Lower nickel content reduces costs compared to sa 240/a 240 uns s30400, making it economical for general-purpose applications.
• Good Corrosion Resistance: Offers better corrosion resistance than sa 240/a 240 uns s43000 in mild environments.
• Excellent Formability: High manganese content enhances formability, ideal for deep drawing in appliance manufacturing.
• Moderate Strength: Provides sufficient strength for architectural and decorative applications, surpassing sa 240/a 240 uns s41000 in formability.

Case Study: An architectural firm in India used sa 240/a 240 uns s20200 sheets for building cladding, achieving a 20% cost reduction compared to sa 240/a 240 uns s30400 while maintaining aesthetic appeal and corrosion resistance in mild environments.
