Advantages of nm500 wear-resistant steel plate

Steel plate has high hardness, strength and toughness, good impact toughness and fatigue strength, good low temperature performance, certain welding performance and the ability to withstand repeated impact and pressure. Therefore, it is widely used as a structural material for various important machinery (such as gears, shafts, worm gears, etc.), and is also used to manufacture some important engineering structural parts.

Advantages of nm500 wear-resistant steel plate:

1. High wear resistance: Because the carbide particles in nm500 wear-resistant steel plate are small and evenly distributed on the entire matrix, it makes Its surface hardness reaches HRC56~57-58; at the same time, due to the strengthening effect of the matrix, the surface layer is strengthened to a certain extent, thus improving its wear resistance.

2. Good machinability: During the cold deformation process, due to the hardening effect of the base metal, the internal stress is reduced. When the processing amount is reduced, it can still maintain its original good machinability.

3. Good corrosion resistance and high temperature oxidation resistance: Under conditions with low sulfur content, it has good corrosion resistance, and as the ambient temperature increases, Its corrosion resistance is significantly improved and it can work above 600°C for a long time;

4. Excellent tempering stability: quenched and tempered steel has high strength, hardness and shaping ability , good hardenability, easy to carry out secondary hardening treatment after water quenching, and not easy to crack;

5. Excellent comprehensive mechanical properties: the ratio of yield value to strength is generally around 1.5, and the yield-strength ratio is average It is greater than 3, therefore, it is beneficial to the load-bearing capacity and cross-sectional characteristics under strong dynamic loads.
