ASTM A516/A516M — Standard Specification for Pressure Vessel Plates, Carbon Steel, for Moderate- and Lower-Temperature Service
Scope
Killed, fine-grain carbon-manganese-silicon plate for welded pressure vessels where improved notch toughness is important: Grades 55, 60, 65 and 70 (tensile 380–620 MPa). Normalizing mandatory above 40 mm; chemistry by thickness; general requirements per A20 (testing, UT, Charpy S5, HIC options by agreement). Adopted by ASME as SA-516 — the most-used ASME carbon-steel vessel plate.
