Chemical Composition

The chemical composition of ASTM A516 GR 70 ensures its suitability for pressure vessels, contributing to its value in the market. The table below outlines its composition per ASTM standards:

Key Notes:

• Carbon: Limited to 0.27% for weldability, balancing cost and performance.
• Manganese: Enhances strength, justifying the premium for high-pressure applications.
• Phosphorus and Sulfur: Low levels improve toughness, adding value for low-temperature service.
• Aluminum: Ensures fully killed steel, enhancing quality and justifying pricing.

Gangsteel’s ASTM A516 GR 70 plates meet ASME SA516 GR 70 standards, with rigorous testing to ensure quality.

Mechanical Properties

The mechanical properties of ASTM A516 GR 70 support its premium pricing for demanding applications. The table below summarizes its properties:

Highlights:

• Tensile Strength: The 485–620 MPa range ensures durability, supporting its cost for high-pressure vessels.
• Yield Strength: A minimum of 260 MPa ensures structural integrity.
• Impact Toughness: Performance at -46°C adds value for cryogenic applications, such as LNG storage.

Compared to ASTM A516 GR 65 and ASTM A516 GR 60, ASTM A516 GR 70 offers higher strength, often justifying a higher price for robust applications.

Applications

ASTM A516 GR 70 is widely used in:

• Pressure Vessels: For oil, gas, and chemical processing, where high strength and toughness are critical.
• Boilers: In power generation, providing thermal stability and durability.
• Cryogenic Equipment: Suitable for LNG storage due to its low-temperature performance.
• Fabrication: Its weldability supports complex assemblies in industrial equipment.

These applications, particularly in high-demand sectors like oil and gas, drive the market value of ASME SA516 GR 70 plates.

Weldability

ASTM A516 GR 70 is fully killed carbon steel, offering excellent weldability with processes like SMAW, GTAW, and SAW. Its low carbon content minimizes weld imperfections, while normalization enhances toughness, adding value for fabrication. Gangsteel supplies plates in normalized or hot-rolled conditions to meet project needs.
