ASTM A387 Grade 12 Alloy Steel Sheets & Plates

ASTM A387 Grade 12 alloy steel sheets and plates are engineered for superior performance in high-temperature and high-pressure environments. This specific grade, often referred to as 1-1/4 Cr - 1/2 Mo, offers excellent resistance to oxidation and scaling, making it a critical material for demanding industrial processes. The material is supplied in both sheet and plate forms, allowing for versatile fabrication in pressure vessel manufacturing, heat exchangers, and structural components exposed to heat.

Unlike standard carbon steel, A387 Grade 12 maintains its mechanical strength at elevated temperatures, reducing the risk of creep and deformation over time. It is typically supplied in normalized or quenched and tempered conditions to ensure optimal toughness and weldability. This alloy steel is widely trusted in the petrochemical, power generation, and chemical processing sectors for its consistent quality and adherence to international standards.
