- Stainless Steel 303 Round Bar
Neeka Tubes is a trusted producer of Stainless Steel 303 Round Bars. We offer these bars in Hex, Square, Round, Forged, and Flat types. With thicknesses from 2 to 150 mm. Stainless Steel 303 is a free-machining grade with added sulfur for better machinability while maintaining strength and corrosion resistance. It is widely used in precision parts and fittings due to its durability, smooth finish and excellent wear resistance making it ideal for machining applications.
SS 303 Round Bar contains 17-19% Chromium and 8-10% Nickel which provides corrosion resistance and strength to it. It has tensile strength of 85000 Psi and yield strength of 45000 Psi. With 50% elongation. Its 8.0 g/cm³ density provides durability. Also 112 BTU-in/hr-ft²-°F thermal conductivity is used to determine the rate at which heat is transferred. Machinability is enhanced when sulfur is added making it suitable for manufacturing of precision parts. It has a shiny surface and it is hard, which makes it suitable for use in the manufacturing process and in industries.
