ASTM A516 GR 702

ASTM A516 GR 70 is a carbon steel plate specified under the ASTM A516 standard for pressure vessels and boilers in moderate and low-temperature services. Renowned for its high strength, toughness, and weldability, this boiler quality steel plate is ideal for applications requiring resistance to corrosive environments, particularly when enhanced with NACE MR0175/ISO 15156 and HIC (Hydrogen Induced Cracking) compliance. It is widely used in industries such as oil and gas, petrochemical, and power generation, making it a top choice for pressure vessel steel plate for sour gas environments.

The ASTM A516 GR 70 specification ensures consistent quality for pressure vessel applications. Key dimensional specifications include: Thickness: 6mm to 300mm  Width: 1500mm to 4050mm Length: 3000mm to 15000mm Plates up to 40mm in thickness are typically supplied in the as-rolled condition, while those over 40mm are normalized to enhance mechanical properties. The A516 Gr 70 plate is manufactured to meet ASTM A516/A516M standards, ensuring suitability for ASTM A516 GR 70 NACE HIC steel plate for oil and gas applications.

The chemical composition of ASTM A516 GR 70 is carefully controlled to ensure optimal performance in corrosive environments. Below is the maximum allowable content for key elements:

Carbon Equivalent (Ceq): Ceq = [C + Mn/6 + (Cr + Mo + V)/5 + (Ni + Cu)/15] % The low phosphorus and sulfur content enhance weldability, making it ideal for boiler quality steel plate for petrochemical applications.

The mechanical properties of ASTM A516 GR 70 ensure its suitability for high-pressure applications:

These properties provide excellent strength and toughness, making A516 Gr 70 plate ideal for pressure vessel steel plate for sour gas environments.

The ASTM A516 GR 70 plate is versatile, serving critical applications:

Pressure Vessels: Used in high-pressure vessels for oil and gas, petrochemical, and power generation industries. Storage Tanks: Ideal for tanks storing liquefied gases or chemicals in pressure vessel steel plate for oil refineries. Boilers: Employed in steam drums and boiler components operating under high pressure. Railcars: Used in railcar tanks for transporting hazardous materials, leveraging its high strength. Offshore Platforms: Suitable for structures exposed to corrosive marine environments.

These applications highlight the plate’s role as a boiler quality steel plate for oil and gas.
