Stainless Steel 316H contains 16–18% chromium, 10–14% nickel, and 2–3% molybdenum, along with a higher carbon content (0.04–0.10%) than 316/316L. Molybdenum enhances resistance to pitting and crevice corrosion while the higher carbon content ensures better creep and tensile strength at elevated temperatures. Mechanical properties include tensile strength around 515 MPa, yield strength around 205 MPa, and elongation of at least 40%. 316H maintains its structural integrity in hot conditions and offers excellent resistance to environments with chlorides. Its combination of strength, toughness, and resistance to corrosion makes it a preferred option for buttweld fittings.
