SS303 is one of the most widely used stainless steel grade. This grade is written as 1.4305 or X8CrNiS18-9 according to EN norm and it is written as UNS S30300 according to UNS norm. 1.4305 stainless steel has one of the best machinability in austenitic stainless steel grades. 1.4305 material is really close to 304 grade stainless steel and the
Machining • A "Ugima" improved machinability version of grade 303 is available in round bar products. • This machines significantly better even than standard 303, giving very high machining rates and lower tool wear in many operations. Annealing • Type 303 should

Grade 303 stainless steel has good resistance to oxidation when intermittently exposed to temperature up to 760°C temperatures. It also has good oxidation resistance in continuous service to 870°C. This, however, is not recommended as 303 is sensitive to carbide precipitation with continuous use at 425-860°C.
