1.7380 — ASTM Equivalent

Holding a datasheet that specifies 1.7380 (EN / DIN)? The valve-grade equivalent, its properties, and certified supply of the matching ASTM grade.

What is the ASTM equivalent of 1.7380?

1.7380 is a EN / DIN designation corresponding to ASTM A182 F22 (2¼Cr-1Mo) (F22 Chrome-Moly Alloy Steel) 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.
