Alloy Steel Plate SA 387/A 387 Oil Tank Boiler Steel Plate
ASTM A 387, ASME SA 387, is one of our most popular products. It is a low alloy pressure vessel quality steel for high temperatures. We have a wide range of plate sizes available and thicknesses range from 6 – 100mm.
The ASME SA387 standards 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.
