Common alloy steel forged fittings are made up of chromium (1–5%), molybdenum (0.5–1.5%), nickel, and other strengthening agents. They offer tensile strength between 500–800 MPa, yield strength of 300–550 MPa, and superior fatigue, creep, and oxidation resistance. The fittings are heat treated (quenched, tempered) to fulfill critical performance specifications, providing long-term service reliability even in cyclic loads and severe temperature conditions.
