What is SA 516 GR 70 Standard?

The SA 516 GR 70 standard is ASME SA 516/SA 516M, specifying carbon steel plates for pressure vessels with 485-620 MPa tensile strength.Gangsteel produces ASME SA 516 GR 70 plates, meeting global standards for critical applications. This article details the standard’s requirements and applications.

SA 516 GR 70 Standard Overview

ASME SA 516/SA 516M is a standard for carbon steel plates used in welded pressure vessels at moderate and low temperatures. Grade 70, with its high strength, is the most robust in the series, equivalent to ASTM A 516 GR 70.

Key Requirements

• Chemical: Low carbon (≤0.31%) for weldability.
• Mechanical: 485-620 MPa tensile, 260 MPa yield.
• Testing: Ultrasonic, HIC, Charpy V-notch.
•  

Applications

• Oil and Gas: High-pressure vessels.
• Petrochemical: Reactors and heat exchangers.
• Power: Boilers up to 450°C.
