ASTM a516 Grade 70 is a versatile pressure vessel plate that’s well-suited to low and moderate temperature applications, making it an ideal material for industrial boilers and pressure vessels. This steel delivers reliable performance in low temperatures, offers good weldability, and boasts superb notch toughness, making it highly suitable for boiler fabrication. It offers an improved yield and tensile strength over the ASTM A516 Grade 65 and 60, and can operate in lower temperatures than A516-65.

Frequently used within the oil, petrochemical and gas industries, a516-70 can be utilised for a wide range of applications.
