NiCr21Mo14W — ASTM Equivalent
Holding a datasheet that specifies NiCr21Mo14W (EN)? The valve-grade equivalent, its properties, and certified supply of the matching ASTM grade.
What is the ASTM equivalent of NiCr21Mo14W?
NiCr21Mo14W is a EN designation corresponding to ASTM B575 / UNS N06022 (Hastelloy C-22) (Hastelloy C-22 / Alloy C-22) 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.
