The addition of molybdenum to 316 stainless steel screws gives it a special structure that resists corrosion. Because it has better resistance to gas chemical corrosion than 304, it is also used as "marine steel". 316 stainless steel can be used under harsh conditions;

18Cr-12Ni-2.5Mo is added with Mo, so its corrosion resistance, atmospheric corrosion resistance and high temperature strength are particularly good. 

It is used in equipment used in our seawater, chemical, dye, papermaking, oxalic acid, fertilizer and other production equipment; it is used in facilities in coastal areas of the photography and food industries.
