1.7335 — ASTM Equivalent

Holding a datasheet that specifies 1.7335 (DIN)? The valve-grade equivalent, its properties, and certified supply of the matching ASTM grade.

What is the ASTM equivalent of 1.7335?

1.7335 is a DIN designation corresponding to ASTM A182 F5 (5Cr-0.5Mo Alloy Steel (Grade F5)) 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.

A182 F5

Chrome-Moly / Alloy Steel

5Cr-0.5Mo Alloy Steel (Grade F5) - forged form.

Service temperature-29°C to +593°C
