The ASME SA387 standard covers the supply of weldable chrome molybdenum alloy steel plates for pressure vessels used in elevated temperature service.
The added molybdenum and chromium provides excellent corrosion resistance and high temperature resistance respectively.
ASME SA387 standard plates are used by the world’s leading fabricators who in turn, supply primarily to the oil and petrochemical industry.
Sourced from some of Western Europe’s & India's finest steel mills, Prosaic Steel and Alloys stock a wide range of ASME SA387 Class 2 plates which are available for shipment worldwide.
