ASME SA387 Grade 91 Steel Plate Where resistance to high temperature and good anti-corrosion characteristics are required, ASME SA387 Grade 91 Steel Plate is a material to consider. It is a pressure vessel grade steel which is used commonly by fabricators who supply the oil and gas industry.

Due to the materials excellent corrosion resistant properties, SA387 Grade 91 is also an option for use in sour service environments. The material has good weldability and with its heat resistant qualities, the material is a highly versatile steel which can be used in numerous applications

The added molybdenum and chromium provides excellent corrosion resistance and high temperature resistance respectively.

ASME SA387 Grade 91 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.
