NiCu30Fe — ASTM Equivalent

Holding a datasheet that specifies NiCu30Fe (EN)? The valve-grade equivalent, its properties, and certified supply of the matching ASTM grade.

What is the ASTM equivalent of NiCu30Fe?

NiCu30Fe is a EN designation corresponding to ASTM B164 / UNS N04400 (Monel 400) (Monel 400) 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.
