A516 Grade 70 Boiler steel plate, A516 Boiler steel chemical composition
A516 Grade 70 Boiler steel plate is a medium carbon alloy designed for use in pressure vessels and boilers. It contains manganese, phosphorus, sulfur and silicon at the highest levels allowed by the ASTM, to produce the strongest carbon steel plates specified by the ASTM. It is a high strength metal, is easy to fabricate and can be securely welded. A516 Grade 70 Boiler steel plate also has good corrosion resistance.
A common trade name for A516-70 plate is PVQ Plate. A516 (or SA516) is available in four grades, Gr55, Gr60, Gr65 and Gr70 with tensile strengths ranging from 380MPa to 620MPa depending on the grade.
