1.4409 — ASTM Equivalent

Holding a datasheet that specifies 1.4409 (EN)? The valve-grade equivalent, its properties, and certified supply of the matching ASTM grade.

What is the ASTM equivalent of 1.4409?

1.4409 is a EN designation corresponding to ASTM A351 CF3M (SS 316L Cast (CF3M)) 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.
