The Stainless Steel 316H Buttweld Fittings are made up of a blend of chromium (16–18%), nickel (10–14%), molybdenum (2–3%), and a higher carbon content (0.04–0.10%) to boost their strength at high temperatures and resistance to creep. These fittings boast impressive mechanical properties, with a tensile strength of around 515 MPa and a yield strength of 205 MPa. The increased carbon content enhances their durability in high-temperature settings, while the molybdenum adds to their resistance against pitting and crevice corrosion, making them perfect for tough and high-stress environments.
