ASTM A516-70 Plate

pvq plate


ASTM A516-70 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. A516-70 plate also has good corrosion resistance.

A common trade name for A516-70 plate is PVQ Plate. A516 plate is also available in grades 55, 60, and 65.
