nm360 wear-resistant plate inspection standards

nm360 wear-resistant plate inspection standard: nm360 is the brand of abrasive wear-resistant steel plate. Its performance is similar to HRB400, but its toughness and hardenability are slightly lower. Used to manufacture heavy-duty or impact-resistant wear parts. Such as gears, bushings, piston pins, etc. It can also be used to manufacture other parts that require a certain strength.

Material introduction:

nm360 is a high manganese steel with good toughness and plasticity, and its strength and hardness are slightly lower than HRC4. It has good work hardening ability, and its plasticity and welding properties in the annealed state are very good. Therefore, it is mainly used to make wear-resistant parts that bear large loads and work at medium speeds. For example, gears, sprockets, sliders, etc.

Characteristics:

1. Good cold bending, hot forming, welding and cutting processability.

2. High surface hardness (HV1200-1500) and high strength at high temperatures

3. High creep strength at high temperatures

4 , good machinability and turnability

5. Good hardenability and good water toughness, suitable for use in various mechanical parts

6. The carbide particles are small and uniform, There is no looseness, good purity, and few inclusions. It is very suitable for automatic lathes.

7. After solution treatment, the difference between surface hardness and core hardness is small, and the tempering resistance and stability are good.

8. The martensite structure formed during quenching is uniform and fine, with high hardness and elasticity.

9. Higher high temperature yield point.

10. Good low temperature impact toughness.

11. Excellent comprehensive mechanical properties and performance.
