Stainless Steel 309S Bolts

The chemical composition of 309S stainless steel bolts is as follows: Carbon (C) 0.30%, Manganese (Mn) 2.00%, Phosphorus (P) 0.045%, Sulfur (S) 0.030%, Silicon (Si) 1.00%, Chromium (Cr) 22-24%, Nickel (Ni ) 13-15%. This grade of stainless steel has great resistance to both corrosion and temperature, making it suitable for various applications such as food processing equipment, chemical process vessels, and petrochemical equipment.

309S SS bolts are widely used in various industrial applications due to their superior properties. Its high-temperature oxidation resistance, heat resistance, and weldability make it the perfect choice for applications such as petrochemical equipment, food processing equipment, and chemical process vessels. Ductility and mechanical strength make it suitable for structural applications such as bridges and buildings. Other properties include corrosion resistance to various acids, chemicals, atmospheric conditions, and saltwater making it suitable for marine and other outdoor environments. Finally, stainless steel 309S bolts offer excellent machinability so that they can be produced in exact sizes with tight tolerances.
