approx — ASTM Equivalent
Holding a datasheet that specifies approx (EN)? The valve-grade equivalent, its properties, and certified supply of the matching ASTM grade.
What is the ASTM equivalent of approx?
approx is a EN designation corresponding to ASTM A352 Grade LCC (Low Temperature Carbon Steel LCC) and 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.
A352 Grade LCC
Carbon SteelLow Temperature Carbon Steel LCC - cast form.
Typical service: LNG terminals and LNG storage tank valves; LPG and propane storage and transfer; Ethylene and propylene plants
A350 Grade LF2
Carbon SteelLow Temperature Forged Carbon Steel LF2 - forged form.
Typical service: LNG satellite and transfer stations; LPG storage, loading, and transfer systems; Refrigeration piping and CO₂ service
