Where resistance to high temperature and good anti-corrosion characteristics are required, ASME SA387 Grade 91 Class 2 carbon alloy steel plate is a material to consider. It is a pressure vessel-grade steel that is used commonly by fabricators who supply the oil and gas industry.

Due to the material’s 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 that can be used in numerous applications.

VINAY METALS can supply SA387 Grade 91 steel plates from stock to global destinations with mill certification and stampings. Certain applications with the Refining and Power Industries along with specific environments within Chemical Plants require grades that address limited corrosion and elevated temperature concerns.

SA 387 Gr 12 is utilized to address low to moderate-temperature challenges. For conditions with higher elevated operating temperatures, our SA 387 Gr 5, SA 387 Gr 9, and SA 387 Gr 91 are often used. The minimum tempering temperatures for these cr / mo grades are:

• SA 387 Gr 12 (1150 °F)
• SA 387 Gr 9 (1250 °F)
• SA 387 Gr 5 (1300 °F)
• SA 387 Gr 91 (1350 °F)
