1.4408 — ASTM Equivalent
Holding a datasheet that specifies 1.4408 (EN)? The valve-grade equivalent, its properties, and certified supply of the matching ASTM grade.
What is the ASTM equivalent of 1.4408?
1.4408 is a EN designation corresponding to ASTM A351 CF8M (SS 316 Cast (CF8M)) 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.
