What is the sexual classification of welded wear-resistant steel?
The material of wear-resistant steel plate is divided into domestic wear-resistant steel plate and imported welded wear-resistant steel plate.
Among them, NM wear-resistant steel plate is divided into: NM400 wear-resistant steel plate, NM450 wear-resistant steel plate, NM500 wear-resistant steel plate, NM600 wear-resistant steel plate.
NM400 wear resistant steel plate NMness is 400HBW, with excellent weldability, impact strength and bending performance.
The NMness of NM450 wear resistant steel plate is 450HBW, the outstanding feature is both high NMness and high toughness, although the NMness is high but as easy to process as NM400.
The NM500 wear resistant steel plate has a NMness of 500HBW, and can withstand severe wear and tear, suitable for working in high-strength ores and corrosive material environments.
NM600 is a very NM wear resistant steel plate with a NMness of 600HBW, typically used for extremely severe wear and used as a replacement for imitation and chrome alloy steels.
