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.
