NM450 steel plate is a high-strength wear-resistant steel plate, widely used in industrial occasions requiring wear resistance.
1. High wear resistance: NM450 steel plate has very high hardness and wear resistance, which can effectively resist wear and extend the service life of equipment.
2. High strength: Compared with ordinary steel, NM450 has higher yield strength and tensile strength, suitable for high stress and high impact applications.
3. Good processing performance: Despite its high hardness, NM450 still has good processability and can be cut, welded, bent and machined.
4. Impact resistance: In addition to high hardness and wear resistance, NM450 also has good impact resistance, suitable for harsh working environments.
NM450 steel plate is a special steel plate with high strength and high wear resistance, mainly used to manufacture wear-resistant parts and wear-resistant structural parts.
NM represents the first letter of the Chinese pinyin of the word “耐” (resistant) and “磨” (wear-resistant), and 450 represents the average Brinell hardness of this steel plate.
Performance characteristics of NM450 steel plate:
High strength: NM450 steel plate has high strength and good plasticity, can maintain stable performance under high load, and is not easy to deform or damage.
Wear resistance: Its surface hardness is high, which can effectively resist wear and scratches and extend the service life. This is one of the most prominent features of NM450 steel plate.
Impact resistance: It can absorb a lot of energy when impacted, reduce the damage to the equipment caused by the impact, and protect the normal operation of the equipment.
Fatigue resistance: It is not easy to suffer from fatigue damage during long-term use, which can ensure the long-term stable operation of the equipment.
Good processing performance: NM450 steel plate can be easily cut, bent, welded and other processing operations, which is convenient for manufacturing wear-resistant parts of various shapes.
Good welding performance: It is not easy to produce cracks or deformation during welding, which can ensure welding quality and welding strength.
Environmental protection: NM450 steel plate will not pollute the environment during production and use, and is an environmentally friendly material.
Corrosion resistance: After special anti-corrosion treatment, it can resist corrosion and oxidation in harsh environments and maintain its long service life.

Mining and mining equipment: such as buckets, mine cars, conveyors and crushers, which can effectively extend the service life of equipment.
Construction and earthmoving: used to manufacture bulldozers, excavator buckets, truck compartments, etc., to resist the wear of soil and rocks.
Waste handling and recycling equipment: such as waste bins, waste sorters and crushers, which can withstand high wear environments.
Agricultural machinery: such as plows, seeders and harvesters, wear-resistant parts, extend the service life of equipment.
Cement plants and steel plants: such as mill liners, chutes, hoppers, etc., can resist the strong wear of materials.
Shipbuilding steel plate refers to the carbon and alloy steel plate used in offshore and marine contructions, common grades are A, B, D, E, AH32/36/40,
316 stainless steel plate is a higher common use stainless steel than 304&304L, it has 2.0 to 3.0% of Molybdenum content which provides better overal
