Stainless Steel 310S Fasteners are made from an austenitic stainless steel alloy containing chromium (24–26%) and nickel (19–22%) with low carbon content for enhanced corrosion resistance. The low carbon level minimizes carbide precipitation, ensuring long-term durability, even after welding. Mechanically, these fasteners provide tensile strength of 515–690 MPa, yield strength of 205–310 MPa, and excellent toughness and ductility. Stainless Steel 310S offers outstanding resistance to oxidation, scaling, and thermal fatigue at elevated temperatures. The alloy also ensures good formability, weldability, and structural stability, making it suitable for demanding high-temperature and industrial fastening applications.
