A516Gr70 steel

ASTM A516Gr70 steel plate/sheet,ASTM A516Gr70 steel plate/sheet, under ASTM standard, we can regard A516Gr70 steel plate/sheet for simple pressure vessels steel.

ASTM A516Gr70/ASME SA516Gr70 is an excellent choice for service in lower than ambient temperature applications, has excellent notch toughness and is used in both pressure vessels and industrial boilers.ASTM A516Gr70/ASME SA516Gr70 offers greater tensile and yield strength when compared to ASTM A516Gr65/ASME SA516Gr65 and can operate in even lower temperature service.
