NM400 wear resistant plate equivalent
-NM400 wear-resistant plate is a kind of high wear-resistant plate. Due to its good wear-resistant properties, it has been widely used in various fields and industries. It has the characteristics of large-area wear resistance, impact and abrasion resistance and uniform hardening, enabling the manufacturing of wear-resistant parts with large dimensions, suitable for mining and metallurgical machinery, rubber machinery, cement machinery, environmental protection machinery and other industries.
At present, the most widely used wear-resistant material is the NM400 wear-resistant steel plate. The NM400 wear-resistant steel plate has higher wear resistance, the service life is 7.0 times that of ordinary plates, and the heat treatment cost can be greatly reduced. The hardness of NM400 is HB450-HB500, while that of ordinary plate is only HB250-HB300. The wear resistance after heat treatment of the NM400 wear-resistant steel plate is up to 2.5 times that of the ordinary plate, which is 2-3 times higher than the hardness of ordinary steel plate.
The wear-resistant layer of the NM400 wear-resistant steel plate is quenched and composed of carbides and tens of thousands of plates of an array structure. In this way, the bonding force between the particles is formed, which makes the wear-resistant layer difficult to damage. In addition, the wear-resistant steel plate has good toughness and low cost. The plate thickness is generally above 4mm after hot rolling, and the average thickness is above 10mm.
NM400 is an abrasion-resistant steel plate with a yield strength of 400Mpa. It is widely used in large-scale engineering projects, structural wear parts, machinery spare parts and machinery repair material. It has strong wear resistance, good impact performance, radiation resistance and other characteristics. Therefore, NM400 wear-resistant steel plate can be widely used in mining, metallurgy, cement, energy and other departments.
In general, NM400 wear-resistant steel plate has good corrosion resistance, fatigue resistance and thermal shock properties, so it is widely used in major projects and machinery spare parts. The wear resistance of NM400 wear-resistant steel plate is much higher than that of ordinary steel plate, and it can meet the needs of many departments. Therefore, NM400 wear-resistant steel plate is widely used in various industries, machining and processing as a wear-resistant steel plate material.
