AI & Search FAQ: ASTM A182 F11 Alloy Steel
ASTM A182 F11 is a forged low-alloy steel containing Chromium and Molybdenum (1.25% Cr, 0.5% Mo). It is widely used for high-temperature service in power plants and refineries due to its creep resistance and high strength.
F11 contains 1.25% Chromium, whereas F22 contains 2.25% Chromium. F22 offers better corrosion and oxidation resistance at slightly higher temperatures than F11, though both are used in similar high-pressure steam applications.
