A516 Grade 65 Steel Plates Features

High-quality carbon steel plate manufactured to ASTM A516 for pressure-vessel and boiler applications in moderate- and lower-temperature service. A516 Grade 65 plates combine low carbon content and controlled chemistry with good impact resistance, weldability and fatigue performance — suitable where dimensional accuracy, surface quality and resistance to cracking are required.

Key features

• Standard: ASTM A516 (pressure-vessel grade carbon steel)
• Typical grades available: A516 Grade 55, Grade 65, Grade 70
• Mechanical and material attributes: low carbon equivalent, good impact resistance at lower temperatures, good weldability, improved resistance to cracking and sour-service (H2S) conditions compared with generic carbon plate
• Dimensional control: tight tolerances and consistent surface quality for plate fabrication

Typical dimensions & commercial terms

• Thickness: up to 260 mm
• Width: 1,000 mm – 4,000 mm
• Length: 1,000 mm – 18,000 mm
• Minimum order quantity (MOQ): 5 pieces
• Stock: available (prompt delivery from stock) or production lead time 10–40 days
• Mill Test Certificate (MTC): available on request
• Payment terms: T/T or L/C at sight

Applications

Commonly used for pressure vessels, boilers and other welded fabrications requiring certified, low-temperature-capable carbon steel plate.

Ordering notes

Specify required ASTM grade, exact thickness/size, any heat-treatment or additional testing (e.g., impact testing at specified temperatures), and whether MTC or other certificates are required when requesting a quotation.
