Products Description
ASME SA36 is the American Society of Mechanical Engineers (ASME) specification for carbon structural steel, mirroring ASTM A36 but certified for use in boilers, pressure vessels, and related components under ASME Boiler and Pressure Vessel Code.
It applies to plates, shapes, and bars for riveted, bolted, or welded constructions in bridges, buildings, and general structural work. The "SA36" denotes a minimum yield strength of 36,000 psi (250 MPa), positioning it as a low-carbon steel that's straightforward to fabricate and machine.
Clients often inquire: Is ASME SA36 identical to ASTM A36? Essentially, yes-they share the same chemical and mechanical properties, but SA36 includes ASME certification for pressure-retaining applications.
At GneeSteel, we produce SA36 plates via hot-rolling, offering a robust finish with options for pickling and oiling to boost corrosion resistance. This mild steel variant (carbon content 0.25-0.29%) eliminates the need for heat treatment in most cases, optimizing efficiency and budget.
