ASME SA 387 GRADE 91 Class 2

ASME SA 387 GRADE 91 Class 2

Where resistance to high temperature and good anti-corrosion characteristics are required, is a carbon alloy 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, ASME SA 387 GRADE 91 Class 2 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.
