Isis Metals, Manila, Philippines, is a company that specializes in the production and export of Stainless Steel 303 Hexagon Bars and Rods, renowned for its exceptional corrosion resistance and high machinability. These Type 303 Hex Bars are optimized to function effectively in corrosive conditions and exhibit exceptional resistance against chloride-ion stress corrosion cracking, as well as having a stable austenitic structure. Chromium and molybdenum alloyed with SS 303 Hex Bars for their improved strength, these work very effectively against the reducing and oxidizing acids like phosphoric and sulfuric acids. These make SS 303 Hex Bars a trustworthy option for chemical processing, petrochemicals, food processing, and offshore processes.
Stainless Steel 303 Hex Bars and Rods consist of 17–19% chromium, 8–10% nickel, and 0.15% sulfur for enhanced machinability, together with traces of molybdenum, phosphorus, and manganese. The specially controlled sulfur addition improves cutting performance without reducing corrosion resistance. They have a tensile strength of 500–750 MPa, yield strength of 190–450 MPa, and hardness of up to 229 HB. The alloy maintains great ductility, strength, and compressive strength under rigorous mechanical and environmental stresses and is appropriate for high-performance and high-precision engineering applications.

Stainless Steel 303 offers excellent machinability due to sulfur addition, good corrosion resistance, high toughness, and decent strength. It's ideal for precision machining, retaining mechanical properties while being easily cut.
Stainless Steel 303 has superior machinability due to added sulfur but slightly reduced corrosion resistance compared to 304 or 316. It balances easy machining with moderate corrosion resistance for non-critical environments.
Common finishes for Stainless Steel 303 hex bars/rods include polished, brushed, and matte finishes. Treatments like passivation improve corrosion resistance, while electropolishing enhances durability and appearance. Protective coatings and bead blasting offer additional surface refinement options.
Stainless Steel 303 Hex Rods and Bars are widely applied across industrial sectors requiring high machinability and corrosion resistance. They are best suited for producing precision parts like bolts, nuts, shafts, fittings, valves, and gears. Widely applied in petroleum refineries, chemical processing facilities, food processing machinery, and marine applications, SS 303 Hex Bars provide better stress and harsh condition performance. Additionally, because they are durable and resistant to oxidation, SS 303 Hex Bars can be found in aerospace, automobile, and medical industries. Offshore oil operations and waste management systems also favor SS 303 Hex Bars due to their reliability and strength.
We provide products that come with both mill test certificates and third-party test certificates, ensuring the highest standards of quality and compliance.
