SA516 Grade 70 (also listed as SA516 Grade 485 in some references) is an ASME-specification carbon steel plate produced for welded pressure-vessel service at moderate and lower temperatures. It combines good weldability with improved notch toughness, making it suitable for stationary pressure vessels, boilers and other pressurized equipment.
Key specifications
- Standard: ASME SA516
- Grade: 70 (SA516 Gr 70 / SA516 Gr 485)
- Typical thickness range: 5 mm – 205 mm
- Typical widths: 1,500 mm – 2,500 mm
- Typical lengths: 6,000 mm – 12,000 mm
- Manufacturing process: Hot-rolled (HR)
- Heat treatment options: rolled, controlled-rolled, normalized, normalized + tempered (N+T) or quenched + tempered (QT) as required
- Common delivery conditions: hot-rolled, controlled-rolled, normalized (confirm delivery condition for thicknesses > 40 mm)
Applications
- Welded pressure vessels and storage tanks
- Boilers and heat exchangers
- Petrochemical and chemical processing equipment
- Power generation equipment (including hydropower penstocks and high‑pressure pipes)
- Components requiring good notch toughness at moderate / low temperatures
Quality & testing
Plates are produced to meet ASME SA516 requirements. Typical commercial offerings can include mill test certificates (MTC), ultrasonic or radiographic testing, mechanical test reports and surface/edge treatments on request. Buyers should confirm required delivery condition, heat treatment, testing and certifications at time of enquiry.
Ordering & customization
Available to order in multiple thicknesses, widths and lengths. Common finishing, edge preparation and protective packing options can be provided for shipment. For precise tolerances, certificate types, stamping or custom processing (e.g., cutting, beveling), please specify requirements when requesting a quotation.
