SS303 is Japanese stainless steel grade SUS303.
SUS303 is austenitic type easy-to-cut stainless wear-resistant burnished steel, in order to improve the performance of the steel, can be added to the steel of not more than 0.60% of molybdenum, can be resistant to ablative corrosion, the product of good machinability and burnished, corrosion-resistant.
SUS303SESe is an improved version of SUS303!
