High-strength chromium-molybdenum alloy plates produced to ASTM A387/A387M for pressure-vessel and high-temperature applications. Available grades: Grade 11, Class 1 (CL1) and Grade 11, Class 2 (CL2). These plates are alloy steel (Cr-Mo) designed for elevated-temperature service where improved creep and rupture strength are required.

Key features and benefits:

  • Conforms to ASTM A387/A387M specification for pressure-vessel steel plates (alloy steel, chromium-molybdenum)
  • Grades: A387 Gr.11 CL1 and A387 Gr.11 CL2 to suit different fabrication and performance needs
  • Supplied as plate form, kept in stock with clean, clear surface condition and ready for shipment
  • Suitable for boilers, pressure vessels, petrochemical equipment, heat exchangers and other high-temperature, high-pressure fabrications
  • Good weldability and machinability when processed by appropriate procedures for alloy steels

Supply and services:

  • Stocked inventory for immediate or short-lead deliveries
  • Quality documentation and test reports can be provided on request to support traceability and inspection requirements
  • Plates are inspected and prepared for export or domestic shipment according to customer specifications

If you require specific sizes, thicknesses, heat numbers, or certification formats (MTC / third-party inspection), provide your technical requirements and quantity to confirm availability and lead time.
