SS 303 Round Bars Supplier

Om Steel is a leading in export quality SS Seamless 303 Round Bars Suppliers in India which provides a wide range of sizes from 4 mm to 100 mm (3/16 inch to 4 inches) in diameter. We provide high ductility steel to avoid failures in brittle along with ensuring a high degree of safety.

It has an improved machinability due to the increased sulphur content, however, the sulphur content slightly decreases the corrosion resistance and lowers its weldability.

Om steel Industries provides a wide range of stainless steel grades required in most of the machining equipment and structural applications. We export SS 303 Round bars worldwide. Its features include:

  • High Tensile Strength
  • Good corrosion resistance
  • Free machining
  • Not suitable for welding or forming.
