SA387 Grade 9 Steel Plate – weldable carbon steel plates for pressure vessels and boilers used in elevated temperatures. The material benefits from added chromium and molybdenum which gives the steel greater corrosion resistance and resistance to heat. SA387 Grade 9 is used by fabricators who serve the oil, gas and petrochemical industry.
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.
ASME SA387 Grade 9 standard plates are used by the world’s leading fabricators who in turn, supply primarily to the oil and petrochemical industry. Applications for ASME SA387 include pressurized vessels, industrial boilers, heat exchangers and Pipe work.
