High-strength alloy steel plates supplied to the A/SA A387 specification — Grade 22, Class 1 and Class 2 — designed for welded boilers and pressure vessels operating at elevated temperatures. These plates are produced for pressure-service applications where improved creep strength and elevated-temperature performance are required.

Key features

  • Conforms to A/SA A387 Grade 22 (Class 1 & Class 2) specification for pressure-vessel use
  • Thickness range in stock: 5–150 mm
  • Supplied as full plates or cut-to-size pieces from port warehouses, ready for shipment
  • Mill test certificates (MTC) available with each shipment
  • Typical uses: welded boilers, pressure vessels, petrochemical, refinery and power-generation equipment

Benefits

  • Elevated-temperature strength and creep resistance suitable for high-temperature service
  • Wide thickness availability supports small fabrications through heavy pressure-vessel construction
  • Fast supply from port-stocked inventory reduces lead times

Available services and options

  • Mill Test Certificates (3.1/3.2) and inspection documentation
  • Cut-to-size, edge conditioning and packaging for export
