ASME SA 387 GRADE 12 Class 2
Engineered for use in elevated temperature service, ASME SA387 Grade 12 Steel Plate is a chrome molybdenum carbon alloy steel for use in weldable pressure vessels and industrial boilers.
The material benefits from added chromium which provides excellent corrosion and oxidation resistance making it ideal for sour service applications in the oil and gas industry.
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. Applications for ASME SA387 include pressurized vessels, industrial boilers, heat exchangers and Pipe work.
