ASTM A790 / A790M is an international standard specification for intended for general corrosive service. Often referred to as , these pipes are engineered to deliver superior performance in demanding industrial environments.
, making it a preferred choice for applications where standard austenitic steels (like 304 or 316) might fail.
Key Features of ASTM A790
Ferritic/Austenitic (Duplex) Stainless Steel.
Seamless and Welded Pipe (typically larger diameters than tubing).
Combines high strength (approx. 2x yield strength of 304/316) with excellent resistance to chloride stress corrosion cracking.
Includes UNS S31803, S32205, S32750 (2507), S32760 (Zeron 100), and others.
ASTM A790 piping is essential for industries requiring robust, durable infrastructure:
Offshore platforms, flow lines, and risers.
Transporting aggressive acids and solvents.
Seawater cooling systems and desalination plants.
Flue gas desulfurization systems.
Why Choose ASTM A790?
This standard mandates strict chemical composition limits and mechanical property requirements to ensure safety and longevity. All pipes must be heat-treated (solution annealed) and pass hydrostatic or nondestructive electric tests.
supplies high-quality ASTM A790 duplex stainless steel pipes, fully compliant with international standards and certified for critical industrial applications.
