Stainless Steel 303 is an austenitic stainless steel alloy that’s been enhanced with sulfur and phosphorus to boost machinability. It generally contains 17–19% chromium, 8–10% nickel, along with trace amounts of sulfur (~0.15%) and phosphorus (~0.04%). This alloy has a tensile strength of about 620 MPa, a yield strength of around 310 MPa, and an elongation of 30%. While it may have slightly lower corrosion resistance compared to 304, its mechanical properties and outstanding machinability make it a go-to choice for crafting precision parts with tight tolerances. Plus, it retains good weldability and strength across various environments.

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 Bars and Rods are commonly used in applications that require easy machining without compromising on strength and corrosion resistance. They’re frequently found in the manufacturing of gears, shafts, screws, and fittings, making them ideal for automotive, aerospace, and machinery components. Additionally, they’re utilized in food processing equipment, valve parts, and hydraulic systems where precise, complex shapes are essential. Their excellent machinability helps cut down on production time and costs, making them a favored option in general engineering, instrumentation, and fastener industries that demand reliable performance and durability in moderately corrosive settings.
We provide products that come with both mill test certificates and third-party test certificates, ensuring the highest standards of quality and compliance.
