1. 420 stainless steel has wear resistance and high hardness, but its price is relatively low. 2. There is also 430 stainless steel, which has good corrosion resistance, but the process performance is relatively poor. 3. 304 stainless steel, commonly used to make insulation cups, has the advantages of corrosion resistance and high temperature resistance. 4. Duplex stainless steel, corrosion resistance and welding performance are outstanding.
Stainless steel can be divided into four categories: stainless steel, acid resistant stainless steel, heat resistant stainless steel, and low-temperature stainless steel.
1. Stainless steel refers to the steel that is resistant to corrosion in the atmosphere and weak corrosive medium.
2. Acid resistant stainless steel refers to the steel that can resist corrosion in various strongly corrosive media.
3. Heat resistant stainless steel refers to stainless steel with high oxidation resistance and high enough high temperature strength under high temperature.
4. Low temperature stainless steel is an alloy steel suitable for applications below 0 ℃. It is called ultra-low temperature steel if it can be used below - 196 ℃.
