4mm NM450 Steel Plate
nm450 wear-resistant plate is a kind of high hardness wear-resistant steel plate, with excellent wear resistance and high strength. It is made of hot rolling process and has excellent wear resistance and impact resistance. nm450 wear-resistant plate is widely used in mining, construction, metallurgy, coal and other industries, is an ideal wear-resistant material. It can effectively resist wear and impact, improve the service life of equipment and reduce maintenance costs. The nm450 wear-resistant plate also has good weldability and machinability, and can be cut, bent and welded according to needs.
The main features of nm450 wear plate include:
High hardness: The hardness of nm450 wear-resistant plate reaches 450HB or more, which has excellent wear resistance and can effectively resist wear and scratches.
High strength: The tensile strength of nm450 wear-resistant plate reaches more than 1200MPa, which has high strength and can withstand greater pressure and impact force.
Good weldability: nm450 wear-resistant plate has good weldability and can be processed and repaired by welding and other means.
Good machinability: The nm450 wear-resistant plate can be cut, bent and stamped according to needs, and is suitable for equipment of various shapes and sizes.
High wear resistance: nm450 wear plate has very high wear resistance, can effectively resist wear and impact, extend the service life of the equipment.
