Stainless Steel 316H is a high-carbon variant of 316, featuring about 16–18% chromium, 10–14% nickel, 2–3% molybdenum, and 0.04–0.10% carbon. The added carbon boosts its high-temperature strength and creep resistance. SS 316H bolts showcase a tensile strength ranging from 515–700 MPa, a yield strength of around 205–290 MPa, an elongation of 40–50%, and a hardness between 80–90 HRB. These bolts maintain their mechanical integrity under thermal stress, providing excellent corrosion resistance in acidic and chloride-rich environments. Their strength and durability make them perfect for high-temperature applications where long-term stability is key.
