Stainless Steel 310/310S is an austenitic alloy made of mostly chromium and nickel and provides excellent high-temperature oxidation and corrosion resistance. Stainless Steel 310 has more chromium and nickel content, which gives it better oxidation resistance, whereas 310S is a low carbon variant that reduces carbide precipitation when the material is welded, making it suitable for welded applications. The material has tensile strength of 520 MPa (75 ksi) and yield strength of 205 MPa (30 ksi) and is strong and resistant to high-temperature conditions. Its characteristic attributes make it especially useful in applications where heat and hostile chemical atmosphere resistance is needed.
