1. Overview of ASTM A516 GR 70 Specification

The ASTM A516 GR 70 specification, part of the ASTM A516 standard, covers carbon steel plates designed for pressure vessels and boilers operating in moderate and lower-temperature environments. This grade is widely used in industries such as oil and gas, petrochemical, and marine due to its high tensile strength, excellent weldability, and reliability at temperatures as low as -46°C.

• Supply Condition: Plates 40mm and under are typically supplied in the as-rolled condition, while plates over 40mm must be normalized. Customers can also request normalized or stress-relieved plates.
• Thickness Range: 4mm to 300mm.
• Width Range: 1500mm to 4050mm.
• Length Range: 3000mm to 15000mm.
