SUS303Se
Austenitic stainless steel SUS303Se
Overview and features of SUS303Se:
SUS303Se is a type of austenitic stainless steel. It is also known as a free-machining stainless steel, wear resistant steel as well as ablation resistant steel. Its ablation resistance, machining and corrosion resistance can be improved greatly by adding an appropriate amount of molybdenum.Chemical composition of SUS303Se (%):
