Stainless Steel 310 Fasteners are crafted from a high-chromium (24–26%) and high-nickel (19–22%) austenitic stainless steel alloy, specifically designed for high-temperature applications. This alloy also includes carbon up to 0.25%, which boosts creep resistance and strength at elevated temperatures. The mechanical properties feature a tensile strength of around 515 MPa, yield strength of 205 MPa, and an elongation of 40%. SS 310 fasteners provide outstanding oxidation resistance up to 1150°C, along with impressive ductility and toughness. These fasteners come in various sizes and configurations to meet the needs of different industrial applications and operating conditions.
