Abrasion Resistant Steel Plate Grades NM450

Abrasion Resistant Steel Plate Grades NM450

NM450 wear-resistant steel plate processing properties:

During processing, it should be ensured that the calculation, design and processing methods meet the requirements of the material itself, meet the requirements of the latest processing technology, and meet the requirements of the actual use of the product in the future. The appropriate material should be selected, taking into account high strength and hardening while referring to the recommendations of EN1011.

Despite its high hardness, the NM450 can still be cold-formed. However, it should be noted that with the increase of yield strength, the deformation force and resilience required for steel plates of the same thickness should also be increased. It is recommended to sand the flame cutting edge or cut edge of the cold bending area to prevent cracking.

NM450 wear-resistant steel plate heat treatment:

The hardness is obtained by accelerated cooling from the austenitizing temperature. After thermoforming, only re-quenching can restore the hardness. The hardness obtained by re-quenching will be different from the hardness measured at the factory, because of the difference in capacity between the quenching equipment used in the production of steel plates and the quenching equipment owned by the processing plant. The hardness of the steel plate will not decrease significantly when heated to about 200℃.
