Stainless Steel 321H Tubing is a titanium-stabilized austenitic stainless steel that boasts an enhanced carbon content (0.04–0.10%) for better high-temperature strength. Its composition includes Chromium (17–19%), Nickel (9–12%), and Titanium (≥5x C min.). This grade of stainless steel is known for its excellent resistance to intergranular corrosion, even when exposed to temperatures ranging from 427 to 816°C. It provides a tensile strength of 515–730 MPa, a yield strength of 205 MPa, and a minimum elongation of 40%. These mechanical properties, along with its resistance to oxidation and creep, make 321H an ideal choice for high-temperature, high-stress environments that demand stable structural performance.
