Dhruv Metals, based in Hyderabad, India, is a trusted manufacturer and supplier of **Stainless Steel 303 Bars and Rods**. They’re known for their outstanding machinability, corrosion resistance, and mechanical strength. Stainless Steel 303 is an austenitic stainless steel that’s been specially formulated for better machinability by adding sulfur. At Dhruv Metals, we produce SS 303 bars and rods that meet international standards, ensuring consistent quality and performance for various industries, including automotive, instrumentation, fasteners, and precision machining.
Typically, Stainless Steel 303 Bars and Rods consist of chromium (17.0–19.0%), nickel (8.0–10.0%), sulfur (at least 0.15%), and carbon (≤0.15%), along with small amounts of manganese, silicon, phosphorus, and iron as the base. These bars boast a tensile strength of about 585 MPa, a yield strength of 240 MPa, an elongation of 35%, and a Brinell hardness of up to 230 HB. The sulfur addition helps with chip-breaking during machining while still maintaining good corrosion resistance and strength.

Stainless Steel 303 Bars and Rods are commonly used in industries such as aerospace, automotive, medical, and manufacturing. They are perfect for producing components like fasteners, surgical instruments, fuel lines, and machinery parts.
Yes, Stainless Steel 303 Bars and Rods offer excellent corrosion resistance, particularly against a range of acids, chemicals, and weathering, making them suitable for use in both industrial and outdoor environments.
Stainless Steel 303 Bars and Rods are specifically designed for excellent machinability due to the addition of sulfur and phosphorus, which improve cutting and machining performance. This makes them ideal for high-precision applications like fasteners, shafts, and gears.
You’ll find Stainless Steel 303 Bars and Rods in a variety of applications that require excellent machinability and moderate corrosion resistance. Common uses include shafts, gears, screws, nuts, bolts, bushings, valve components, and precision parts in electronic, aerospace, and mechanical systems. SS 303 is particularly well-suited for automated CNC machining and screw machines, providing smooth finishes and minimizing tool wear. While it’s not the best choice for marine or highly corrosive environments due to its sulfur content, SS 303 remains a top pick for high-speed manufacturing and high-volume precision parts.
We provide products that come with both mill test certificates and third-party test certificates, ensuring the highest standards of quality and compliance.
