ASTM A790 S32205 Duplex Stainless Steel Pipe
ASTM A790 S32205 is a specification for duplex Stainless Steel Pipe. Duplex stainless steel is a type of stainless steel that contains both austenite and ferrite phases in its microstructure, resulting in enhanced mechanical properties and corrosion resistance compared to standard austenitic stainless steels.
S32205 is the grade designation for this specific duplex stainless steel, which has a chemical composition that includes chromium, nickel, molybdenum, and nitrogen. It offers good resistance to pitting, crevice corrosion, and stress corrosion cracking, making it suitable for various applications in industries such as oil and gas, chemical processing, and marine environments.
The ASTM A790 specification covers seamless and welded Duplex Stainless Steel Pipes for general corrosive service and high-temperature applications. It specifies the dimensions, mechanical properties, and testing requirements for these pipes.
Overall, ASTM A790 S32205 duplex stainless steel pipes are widely used in various industries due to their excellent combination of strength, corrosion resistance, and cost-effectiveness.
