ASME SA516 Grade 70 Boiler Quality Steel and Pressure Vessels Steel Plate
ASME SA516 Grade 70 Boiler Quality Steel and Pressure Vessels Steel Plate
ASME SA516 Grade 70 Size:
Thickness: 6MM to 300MM,
Width: 1500mm to 4050mm,
Length: 3000mm to 15000mm
ASME SA516 standard specification for pressure vessel plates, carbon steel for moderate and lower- temperature service.
For plates thinner than 40mm normally supply as rolled. Plates above 40mm thick are normalized. For SA516 Grade 70, which is one of most popular steels.
