Abrasion Resistant Steel Plate NM300
1. High strength and hardness
2. Excellent wear resistance
3. Good toughness and impact resistance
4. Ability to withstand high stress and abrasive environments
5. Easy to machine and weld
6. Long service life
Abrasion resistant steel plate NM300 is a high-strength wear resistant steel plate with high wear resistance. It has good weldability, bending and impact resistance. It has high toughness and excellent resistance to sliding wear, impact wear and wear-reducing effect. It can be used in high wear areas such as mining equipment, cement plants and earthmoving equipment. The hardness of this steel plate ranges from 300-350HBW, making it very durable and effective in high wear situations. NM300 steel plate is typically used in mining, construction and manufacturing applications where heavy wear and tear are common.
