Stainless steel type 1.4305 is popularly known as grade 303 stainless steel.<\/p>

Grade 303 is the most readily machineable of all the austenitic grades of stainless steel.<\/p>

303 stainless steel<\/strong> <\/a>is an austenitic stainless steel<\/strong> specifically engineered for improved machinability<\/strong> while maintaining good corrosion resistance. It is widely used in precision-machined components<\/strong> where ease of machining is critical.<\/p>

The machineable nature of grade 303 is due to the presence of sulphur in the steel composition. Whilst the sulphur improves machining, it also causes a decrease in the corrosion resistance and a slight lowering of the toughness. The corrosion resistance of type 303 is lower than that for 304<\/a>. The toughness is still excellent as with other austenitic grades.<\/p>

Property data given in this document is typical for bar products covered by EN Standards. ASTM, or other standards may cover products sold. It is reasonable to expect specifications in these standards to be similar but not necessarily identical to those given in this datasheet.<\/p>\t\t\t\t\t\t\t\t<\/div>\n\t\t
