ASTM A182 F5 also known as X 12 CrMo 91 (1.7386) is a high-performance alloy steel known for its exceptional high-temperature strength, excellent toughness, and good wear resistance. This material is particularly suitable for demanding applications in the power generation, petrochemical, and machinery manufacturing industries, where components are exposed to extreme temperatures and significant mechanical stress. The alloy’s composition, which includes chromium and molybdenum, enhances its mechanical properties and resistance to heat and oxidation, making it ideal for producing boilers, pressure vessels, and high-temperature piping systems.
we utilize advanced open-die forging and precise machining techniques to process A182 F5, X 12 CrMo 91 (1.7386), ensuring components of the highest quality and performance. The combination of high strength, toughness, and heat resistance makes X 12 CrMo 91 (1.7386) a preferred choice for industrial applications requiring robust and long-lasting materials.
Also ASTM A182 F5 is the euivalent grade of 15X5M of Gost standard material
