What is ASTM A182 Alloy Steel F91?
ASTM A182 F91is a Chrome Moly (Cr-Mo) alloy steel grade developed for high- temperature service. The addition of chromium and molybdenum enhances oxidation resistance, hardness, and tensile strength, making it ideal for power plants, heat exchangers, pressure vessels, and petrochemical applications.
The steel’s microstructure maintains its strength even under continuous heat exposure, which is why F91 Alloy Steel Forged Fittings are widely used in boilers, superheaters, and steam lines.
