S32205 — ASTM Equivalent

Holding a datasheet that specifies S32205 (UNS)? The valve-grade equivalent, its properties, and certified supply of the matching ASTM grade.

What is the ASTM equivalent of S32205?

S32205 is a UNS designation corresponding to ASTM A182 F60 (Duplex 2205 Forged (Grade F60)) for industrial valve service. The full grade data is below - equivalence is by nominal chemistry and mechanical class, so confirm composition and heat-treat condition against the governing standard before substituting in critical service.
