Product Attributes
Material Category: Low-carbon steel, with carbon content strictly controlled between 0.18% and 0.24%. Extremely low levels of harmful elements such as phosphorus and sulfur effectively reduce steel brittleness.
Compliance Standard: Must meet ASTM A516/A516M specifications. This standard explicitly defines core metrics including chemical composition, mechanical properties, dimensional tolerances, and testing methods. It serves as the basis for product qualification.
Common Specifications: Thickness range: 6mm–300mm. Width is customizable. Lengths can be cut to customer specifications based on equipment dimensions, minimizing subsequent processing waste.
ASME certified, 6mm-300mm thickness.
Trusted A516 GR70 supplier with global delivery.

Carbon Steel Plate A516 Gr 70 Features
Carbon Steel Plate A516 Gr 70 is a widely used pressure vessel steel plate designed for moderate and lower temperature service. It offers an excellent balance of strength, toughness, and fabrication performance, making it a preferred material for boilers, pressure vessels, and industrial equipment.
- High Strength for Pressure Vessel Applications
A516 Gr 70 provides higher tensile and yield strength compared to lower-grade carbon steel plates. Its strength level allows the plate to withstand higher internal pressure, enabling safer and more efficient structural design in pressure vessels and boilers.
- Excellent Toughness at Moderate and Low Temperatures
The plate demonstrates good notch toughness and impact resistance, which is essential for equipment operating under pressure and fluctuating temperatures. This performance helps reduce the risk of brittle fracture in critical applications.
- Good Weldability and Fabrication Performance
Despite its higher strength, A516 Gr 70 maintains good weldability. It performs well in cutting, forming, bending, and welding processes when proper procedures are followed, making it suitable for medium and thick plate fabrication.
- Stable Performance in Medium and Thick Plates
Carbon Steel Plate A516 Gr 70 is commonly supplied in medium and thick plate forms, ensuring consistent mechanical properties across different thicknesses. This stability is especially important for large-scale pressure vessel and boiler manufacturing.
- Wide Industrial Application Acceptance
A516 Gr 70 is widely accepted and specified in industries such as power generation, petrochemical, oil and gas, and chemical processing, meeting the requirements of various international pressure vessel standards.
Our Factory
Product Inspection
Chemical Composition Testing
Each batch of steel plates undergoes sampling for spectral analysis or chemical titration to verify that elemental content-including carbon, manganese, and silicon-falls within standard ranges. Products are accompanied by inspection reports.
Mechanical Properties Testing
Tensile, impact, and bending tests validate compliance with standards for tensile strength, yield strength, impact energy, and ductility.
Non-Destructive Testing
Additional inspections can be provided per customer requirements to detect internal defects such as laminations or cracks.
Dimension and Appearance Inspection
Verifies plate thickness, width, and length against order specifications. Ensures surfaces are free of visible defects like cracks or pitting, and edges are free of burrs.
