Stainless Steel 321 and 321H are austenitic stainless steels that are stabilized with titanium. This titanium helps prevent chromium carbide precipitation, boosting resistance to intergranular corrosion at high temperatures. The 321H grade features a higher carbon content, which enhances its creep strength. These stud bolts are known for their high tensile strength, impressive toughness, good oxidation resistance, and stable mechanical properties even at elevated temperatures. They also boast excellent weldability and durability, making them perfect for demanding thermal and pressure applications.
