Wear-resistant stainless steel is mainly used in applications where it can be used to simultaneously with abrasive wear and corrosion. The main alloying elements are alloy steels of chromium and nickel. Generally, in the process of corrosion wear in which abrasive wear is dominant, martensitic stainless steel should be used. In the corrosion and wear process where corrosion is dominant, austenite type should be used. The corrosion resistance of ferritic stainless steel is better than that of martensite and less than austenitic, but its price is lower than that of austenite.
Wear-resistant stainless steel features
In order to save nickel-chromium, wear-resistant stainless steel has developed iron-manganese-aluminum-based stainless steel to a certain extent, and is mainly used for manufacturing parts resistant to erosion, cavitation wear and seawater corrosion. The microstructure of this type of stainless steel in the as-cast state is an austenitic matrix.
When the wear-resistant stainless steel is used, it is resistant to weak corrosive media such as air, steam, water, or stainless steel, which is called stainless steel, and is resistant to chemically corrosive media (chemical, acid, alkali, salt, etc.). It is called acid-resistant steel.
