303 Stainless Steel Bar Description
303 grade stainless steel is also called 1.4305 stainless steel, and 303 grade is the easiest to process of all austenitic stainless steels. The machinability properties of the 303 grade are due to the presence of sulfur in the steel elements. Sulfur can improve machining, but it also reduces corrosion resistance and toughness. The corrosion resistance of the 303 type is lower than that of the 304 type, but the toughness is still as excellent as other austenitic grades.
