Corrosion resistance
Corrosion resistance
Although stainless steel is excellent in corrosion resistance, it is poor in wear resistance. It is difficult to obtain corrosion resistance and wear resistance at the same time.
There are many kinds of stainless steel, please choose the right material.
Corrosion resistance and wear resistance
※ If corrosion resistance and wear resistance are required, see 15MH.
The above figure is an image of corrosion resistance and wear resistance.
