Engineered for use in elevated temperature service, ASME SA387 Grade 12 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.

VINAY METALS stocks SA387 Grade 12 Class 2 and can dispatch to any destination, worldwide. All our plates come 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 temperature 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)
  

Thickness’ from 3/16″ – 6″
Supplemental testing available to simulate application and environmental conditions
These grades can be specified in either Class 1 or Class 2
Computer-controlled processing per customer specifications
