Stainless Steel 310H Tubing is an austenitic stainless steel alloy that contains about 25% chromium and 20% nickel, along with a higher carbon content compared to 310S. This unique composition boosts its high-temperature strength and creep resistance. The alloy excels in oxidation resistance, enduring temperatures up to 1100°C during continuous service, while also maintaining toughness in both high and cryogenic conditions. In terms of mechanical properties, it offers a tensile strength of around 515 MPa, a yield strength of about 205 MPa, and an elongation of 40%. Its structure remains stable under thermal stress, making it perfect for prolonged exposure to extreme heat.
