ASTM A995/A995M for Castings, Austenitic-Ferritic (Duplex) Stainless Steel

ASTM A995/995M, Standard Specification for Castings, Austenitic-Ferritic (Duplex) Stainless Steel, for Pressure-Containing Parts1

The duplex stainless steels offer a combination of enhanced mechanical properties and corrosion resistance when properly balanced in composition and properly heat treated. Ferrite levels are not specified, but these grades will develop a range of approximately 30 to 60 % ferrite with the balance austenite. It is the responsibility of the purchaser to determine which grade shall be furnished depending on design and
service conditions, mechanical properties, and corrosionresistant characteristics.
