Wear resistant steel plate is a kind of special plate product specially used under the condition of large area wear. At present, the commonly Steel NM450 hot rolled carbon plate used wear-resistant steel plate is a plate product made by overlaying a certain thickness of hard and wear-resistant alloy wear-resistant layer on the surface of ordinary low carbon steel or low alloy steel with good toughness and plasticity. The wear-resistant steel plate Steel NM450 hot rolled carbon plate consists of two parts: carbon steel plate and alloy wear-resistant layer.

The quality grade symbols of Q235 steel plate are A, B, C and D respectively. Different grades represent different impact temperatures. Steel NM450 hot rolled carbon plate, Q235A is not required for impact toughness test; Q235B is required for impact toughness test at room temperature (20 ℃); Q235C is required for impact toughness test at 0 ℃; Q235D is required for impact toughness test at - 20 ℃. For the above-mentioned B, C and D grade steels, Akv ≥27J is required under different temperature requirements. At different impact temperature, the impact value is also different.

Wear resistant steel plate has high wear resistance and good impact performance. It can be cut, bent, welded, etc. Wear resistant steel plate can be connected with other structures by welding, plug welding, bolt connection, etc.. It is time-saving and convenient in the process of maintenance site. Wear resistant steel plate Steel NM450 hot rolled carbon plate is widely used in metallurgy, coal, cement, power, glass, mining, building materials, brick and tile industries. Compared with other materials, it has a high cost performance and has been favored by more and more industries and manufacturers.
