SS 303 Round Bar

SS 303 Round BarsSvamitva steel is a renowned supplier and distributor of  SS  303 Round Bars, which represents the optimum in machinability among the austenitic stainless steels. ASTM A276 SS 303 Rods is a non-magnetic, austenitic stainless steel that is not hard enable by heat treatment. AISI  303 Bars is austenitic stainless steel and is similar to AISI 302 but with high sulphur to facilitate machining. Also, ASME SA479 Stainless Steel 303 Rods is the most readily machine able of all the austenitic grades of stainless steel. However, the machine able nature of 303 SS Round Bars is due to the presence of Sulphur in the steels composition.
