The company caters to a variety of sectors, including automotive, chemical, aerospace, and food processing, offering bars and rods that boast excellent machinability, corrosion resistance, and durability. With a strong commitment to innovation and customer satisfaction, Starc Metals has built a reputation as a trusted source for stainless steel solutions, guaranteeing long-lasting performance around the globe.
Stainless Steel 303 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 addition improves machinability while maintaining corrosion resistance. In terms of mechanical properties, they have a tensile strength ranging from 515 to 750 MPa, a yield strength of 205 to 275 MPa, and an elongation of 20 to 30%. This alloy is known for its excellent toughness, moderate hardness, and good corrosion resistance, making it perfect for components that need easy machining along with structural reliability.
