Stainless Steel 308 Bolts

The chemical composition of 308 stainless steel bolts usually contains iron, chromium, and nickel in varying amounts. In addition, molybdenum may also be added to increase corrosion resistance further. The typical chemical composition for the bolts is as follows: Iron (Fe) ~75%, Chromium (Cr) ~17-20%, Nickel (Ni) ~10-14%, and Molybdenum (Mo) ~2-3%.

SS 308 bolts offer excellent resistance to general corrosion, pitting, and crevice corrosion due to their high chromium and nickel content. In addition, adding molybdenum increases the material's overall corrosion resistance. This makes them ideal for use in corrosive environments, such as food processing equipment, marine components, and medical equipment. The bolts also provide good strength at elevated temperatures and excellent ductility.
