1. What role does Mn play in wear-resistant alloy steel?
1 In the low content range, it has a great strengthening effect on steel, improving strength, hardness and wear resistance.
2 reduce the critical cooling rate of steel and improve the hardenability of steel.
3 slightly improve the low temperature toughness of steel.
4 In the high content range, as the main austenitizing element.
2. What role does Si play in wear-resistant alloy steel?
1 Strengthen the iron element to increase the strength and hardness of the steel.
2 reduce the critical cooling rate of steel and improve the hardenability of steel.
3 Improve the corrosion resistance of steel in oxidative corrosion medium and improve the heat resistance of steel.
4 The main alloying elements in magnetic steel.
3. What role does Cr element (chromium) play in wear-resistant alloy steel?
1 In the low alloy range, it has a great strengthening effect on steel, improving strength, hardness and wear resistance.
2 reduce the critical cooling rate of steel and improve the hardenability of steel.
3 Improve the heat resistance of steel, which is the main alloying element of heat-resistant steel.
4 In the high alloy range, the steel has corrosion resistance to corrosive media such as strong oxidizing acids.
4. What role does Mo element (molybdenum) play in wear-resistant alloy steel?
1 Strengthen the ferrite to increase the strength and hardness of the steel.
2 reduce the critical cooling rate of steel and improve the hardenability of steel.
3 Improve the heat resistance and high temperature strength of steel, which is an important alloying element in heat strength steel.https://www.wuxiorient.com/
