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/
