ASTM A516 grade 70 boiler steel plates Size
A516 Grade 70 boiler steel plates are mainly used in welded pressure vessels where improved notch toughness is important.ASTM A516 Grade 70 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.
A516 Grade 70 steel plate offers greater tensile and yield strength when compared to ASTM A516 Grade 65 and can operate in even lower temperature service.
