Stainless Steel 316H Pipe Fittings are made up of iron, containing 16–18% chromium, 10–14% nickel, 2–3% molybdenum, and a higher carbon content compared to 316/316L, which boosts creep resistance and high-temperature strength. They showcase a tensile strength of around 515 MPa, a yield strength of 205 MPa, and good elongation, ensuring both toughness and durability. SS 316H is known for its superior resistance to pitting, crevice corrosion, and chloride stress cracking. Its outstanding mechanical and metallurgical stability at elevated temperatures makes it an ideal choice for high-pressure and high-heat industrial piping systems.
