Steelo Fabrica is involved in a large supply of Stainless Steel 303 Round Bar. We are an acclaimed manufacturer and dealer in these Bars with a large variety. We offer these bars in various fabrication and process industries with great machinability amongst all grades of stainless steel. We produce these Bars in assorted shapes and sizes and are available in cut-to-length according to application demands.
Why is Stainless Steel 303 material selected?
Stainless Steel 303 is acknowledged for its most advantageous machinability rating when used in extensive machining. It is the austenitic grade of Nickel, Chromium, Manganese, Silicon with adequate Carbon and Phosphorous. The Sulphur addition improves machinability and reduces corrosion rates. It is tough and tensile with better hardness properties.

Properties of Stainless Steel 303 Round Bar:
Stainless Steel 303 Round Bar is widely used in high machining applications such as fasteners, heavy machinery, and complex machine parts. These bars are long cylindrical structures produced with different diameters and lengths. They are sturdy structures excellent options for engineering use. Our bars are capable of handling thermal corrosion and stress cracking conditions with optimum strength.
Performance of Stainless Steel 303 Round Bar:
These Round Bars are proposed for mild corrosive surroundings with excellent resistance slightly less than 304 type steel. These bars also offer high-temperature resistance below the sensitizing temperatures. Cold Drawn Round Bars are well finished to improve corrosion resistance with a polished surface. It protects from rust and pitting. Hot Rolled Round Bars are shiny and smooth surfaces used in aircraft gears. Sulfur increase the machinability of the Round Bar but the minor reduction in corrosion-proof properties. These bars are significant functions in dry and mild corrosive surroundings, not suitable in marine ambiance.
Stainless Steel 303 Round Bar is finely resistant to oxidation at high temperatures, but carbide precipitation introduced above 14000F also tends to have irregular scaling consequences. These bars are vulnerable to sensitization due to their high carbon value. Rods are welded with after-weld annealing to reduce weld heat impact.
Applications of Stainless Steel 303 Round Bar:
Electrical switchgear components, Shafts, Bushings, Nuts and bolts, Screws, Aircraft fittings, Gears, etc.
Stainless Steel 303 Bars are a type of stainless steel that contains sulfur and carbon, making it one of the easiest stainless steels to machine. It has good corrosion resistance and good mechanical properties.
UNS S30300 Round Bars have good corrosion resistance, making them resistant to rust and other forms of corrosion. The sulfur content in stainless steel 303 improves its machinability, making it easier to cut, drill & machine than other types of stainless steel.
303 Stainless Steel Round Bars are used in the food processing industry due to their good corrosion resistance and ability to maintain their mechanical properties at high temperatures. They are also used in the Automotive industry for various components such as gears, shafts, & fasteners.
