1.0460 — ASTM Equivalent

Holding a datasheet that specifies 1.0460 (DIN/EN)? The valve-grade equivalent, its properties, and certified supply of the matching ASTM grade.

What is the ASTM equivalent of 1.0460?

1.0460 is a DIN/EN designation corresponding to ASTM A105 (Forged Carbon Steel A105) 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.
