Stainless steel is a kind of good corrosion resistance and mechanical properties of iron-based alloy material, is short for acid-proof stainless steel, resistant to weak corrosive medium such as air, steam, water, or with a stainless steel called stainless steel.
Easy to plastic processing, high smoothness, simple maintenance, can be used without being limited by the geometric shape of manufacturing of complex parts, widely used in functional components, abnormity stand, mechanical components, heat exchanger, injection mould, jewelry and art, etc.
At present, used in 3 d printing of metal stainless steel mainly has three kinds: 316 l austenitic stainless steel, martensite stainless steel 15-5 17-4 ph ph, martensite stainless steel.
