The duplex stainless steels offer a combination of atsm mechanical properties and corrosion resistance when properly balanced in composition and properly heat treated. Duplex S provides excellent guaranteed corrosion resistance, but it should be noted much of the Duplex S currently produced also dual conforms with Duplex S I would like to know whether therre is a casting equivalent for A Gr.

Any casting that meets A also meets A The material may be adopted in ASME codes for specific products or applications, including: Duplex stainless steel is designed to combine improved resistance to stress corrosion cracking including sulfide stress corrosion crackingpitting, crevice corrosion and high strength when compared with other stainless alloys. However, A imposes some additional requirements:.

New Products Prev Next Rotork: K November 21, at 8: The steel castings shall be heat-treated up to required temperature and shall undergo water quenching or rapid cooling by other means after heating. Marking of heat numbers on castings is not required unless specified separately on the purchase order. Shale Work Up in U.
