NM550 Wear Resistant Plate Cutting Processing

NM550 wear resistant plate cutting processing

What material is nm550 steel plate made of

1, the raw material used in nm550 steel plate is steel, after some special smelting and pressing into a process, it changes the internal organizational structure and some element changes, as well as the element content formed a special nature of steel.

What are the technical processing characteristics of nm550 wear-resistant steel plate

1, dimensional stability for high-precision ml550 wear-resistant steel plate, the required accuracy is very high, must maintain dimensional stability, because the cooling speed in the air is very slow, so austenite has some stabilizing effect, will increase some of the remaining austenite in the tissue, nm500 wear-resistant plate number needs to be cold treatment.

2, reduce some quenching deformation, because the nm550 wear-resistant steel plate is relatively slender, and then in the hardening process, there will be deformation, and it must be strictly controlled. Therefore, it is a more critical process in the heat treatment. In the quenching process, the plasticity of cold austenite is used to adjust the value in time, which is a key step to ensure that its qualification rate is improved.

3, in the heating, will reduce the phenomenon of quenching deformation, the need for some gas nitriding or ion nitriding. nm500 wear-resistant steel plate is mainly used to withstand or contact fatigue load, so it needs to have relatively high hardness, and then quenching or surface quenching and chemical heat treatment, it must be followed by low temperature tempering treatment.
