Stainless Steel 316H is essentially a high-carbon variant of 316, featuring 16–18% chromium, 10–14% nickel, 2–3% molybdenum, and a higher carbon content (0.04–0.10%) that enhances strength at elevated temperatures. This unique composition offers outstanding resistance to both corrosion and oxidation. In terms of mechanical properties, these washers have a tensile strength of about 515 MPa, a yield strength of roughly 205 MPa, and an elongation of 40%. Typically, they have a hardness rating of around 95 HRB. These characteristics make 316H washers a reliable choice for maintaining structural integrity under thermal and corrosive stress.
