With a strong commitment to innovation and customer satisfaction, Starc Metals has earned a stellar reputation for excellence, providing stainless steel solutions that promise long-lasting performance across the globe.
Stainless Steel 303 Hex Bars and Rods are made from an austenitic stainless steel alloy that includes chromium (17–19%), nickel (8–10%), manganese, sulfur (0.15–0.35%), and the balance being iron. The sulfur content boosts machinability while still maintaining corrosion resistance. In terms of mechanical properties, they boast a tensile strength of 515–750 MPa, yield strength of 205–275 MPa, and an elongation of 20–30%. This alloy is known for its excellent toughness, moderate hardness, and high machinability, making it perfect for hex bars and rods that require precise machining and structural reliability.

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.
These Stainless Steel 303 Hex Bars and Rods are commonly used in applications that demand high machinability, corrosion resistance, and strength. They are particularly well-suited for creating fasteners, gears, shafts, bushings, and precision components in the automotive, aerospace, and chemical industries. Additionally, they find their place in food processing machinery, instrumentation, and decorative hardware. The unique combination of machinability, strength, and corrosion resistance makes 303 hex bars and rods ideal for components that need precision fabrication, durability, and reliable performance in moderately corrosive environments, ensuring dependable service in industrial, commercial, and structural applications.
We provide products that come with both mill test certificates and third-party test certificates, ensuring the highest standards of quality and compliance.
