A516 Grade 65 Steel Plates Features

High-strength carbon steel plate engineered for pressure-vessel and boiler fabrication in moderate- and lower-temperature service. Supplied to the ASTM A516 specification, Grade 65 offers a balance of toughness, weldability and resistance to brittle fracture for welded pressure vessels, storage tanks and similar welded fabrications.

Key features

• Conforms to ASTM A516 standard for pressure vessel plate
• Grade options available: A516 Grade 55, Grade 65, Grade 70
• Good low-temperature impact resistance and controlled toughness
• Low carbon, micro-alloyed chemical makeup for improved weldability and reduced hydrogen cracking risk
• Good fatigue resistance and anti-cracking performance
• Tight dimensional tolerances and commercially prepared surfaces suitable for fabrication and welding
