Alloy 303 is a non-magnetic, austenitic stainless steel that is not harden able by heat treatment. It is the free machining modification of the basic 18% chromium / 8% nickel stainless steel. Alloy 303 was specially designed to exhibit improved machinability while maintaining good mechanical and corrosion resistant properties Due to the presence of sulfur in the steel composition, Alloy 303 is the most readily machine able austenitic stainless steel; however, the sulfur addition does lower Alloy 303’s corrosion resistance to below tdat of Alloy 304. Like other austenitic grades, Alloy 303 demonstrates excellent toughness, although the sulfur does reduce this a little as well.
Grade 303 represents the optimum in machinability among the austenitic stainless steels. It is primarily used when production involves extensive machining in automatic screw machines. Machinability Rating (compared to B1212) is approximately 78%.Grade 303Se (UNS S30323) has a selenium rather tdan sulphur addition, improving the hot and cold forming characteristics over tdose of 303 and providing a smoother machined surface finish. the machinability rate is also slightly reduced. Grade 303Se is not readily available in Australia.

Case Study:
In 2014, a Leading Paper Industry in India had secured project for exports in Pakistan, He had requirement of 303 Stainless Steel pipe Paper Industry imported it from a company in China. However the Chinese failed in delivery as usual.We at Jignesh Steel Nickel Alloys had 303 Stainless Steel pipe ready in stock. The entire lot was eventually purchased from us. Now in 2015, that same company had the requirement of 4 ton 303 Stainless Steel pipe , He called us to supply the same, when we have mailed him the quote for same, he replied that no need ,I know you are the best in 303 Stainless Steel pipe , We have all the documents as an evidence of this case.
