SA-350 LF2 — ASTM Equivalent

Holding a datasheet that specifies SA-350 LF2 (ASME)? The valve-grade equivalent, its properties, and certified supply of the matching ASTM grade.

What is the ASTM equivalent of SA-350 LF2?

SA-350 LF2 is a ASME designation corresponding to ASTM A350 Grade LF2 (Low Temperature Forged Carbon Steel LF2) 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.
