Chromium (1–1.5%), molybdenum (0.44–0.65%), carbon (0.05–0.15%), manganese, silicon, phosphorus, sulphur, and iron make up alloy steel F12 flanges. Strength, hardness, and heat resistance are all balanced in this composition. Mechanically, F12 flanges have a tensile strength of 485–620 MPa, a yield strength of 275–380 MPa, and an elongation of roughly 20–30%. They function dependably in high-temperature and moderate-pressure environments, guaranteeing durability and structural integrity in crucial applications. Their typical hardness range is 143–197 HB.
