Standard Custom Length Wholesale nm500 steel

NM500 wear-resistant plate for use: mainly in the need for wear-resistant occasions or parts to provide protection, so that the equipment life is longer, reduce the maintenance and downtime brought by maintenance, the corresponding reduction of capital investment.

Wear-resistant steel plate processing
1, the steel plate cutting method is suitable for cold cutting and hot cutting. Cold cutting includes water jet cutting, shearing, sawing or abrasive cutting; Thermal cutting includes oxygen fuel flame cutting (hereinafter referred to as "flame cutting"), plasma cutting and laser cutting.

2, cutting method: Through the relevant process test, master the general characteristics of various cutting methods and cutting thickness range of steel plate.

3, the flame cutting method of wear-resistant steel is as simple as the cutting of ordinary low carbon and low alloy steel. When cutting wear-resistant steel thick plate, you need to pay attention!! As the thickness and hardness of the steel plate increase, cracks appear on the cutting edge. In order to prevent the generation of steel plate cutting cracks, the following recommendations should be followed when cutting:

Cutting cracks: steel plate cutting cracks are similar to hydrogen caused cracks during welding, if the cutting edge of the steel plate cracks, it will appear within 48 hours and several weeks of cutting thickness. The greater the thickness and hardness of the steel plate, the greater the cutting cracks.

Preheat cutting: The most effective way to prevent steel plate cutting cracks is to preheat before cutting. Before flame cutting, the steel plate is usually preheated, and the preheating temperature mainly depends on the quality grade and plate thickness of the steel plate, as shown in Table 2. The preheating method can be carried out by flame burner, electronic heating pad, or heating furnace. In order to determine the preheating effect of the steel plate, the required temperature should be tested on the surface of the hot spot.

Note: Special attention should be paid to preheating, so that the interface of the steel plate should be evenly heated, so as to avoid local overheating in the area in contact with the heat source.

Low-speed cutting: Another way to avoid cutting cracks is to reduce the cutting speed. If full plate preheating is not possible, local preheating can be used instead. The use of low speed cutting methods to prevent cutting cracks, its reliability is not as good as preheating. We recommend cutting
