400 Brinell Steel
China’s NM-series and BW-series wear-resistant steels provide reliable 400 Brinell hardness with excellent abrasion resistance and toughness. These materials are ideal for heavy-duty industrial equipment where wear, impact, and long-term durability are critical. Selecting the appropriate series ensures extended service life, reduced downtime, and optimized operational efficiency.
- Description
Steel with 400 Brinell hardness (HBW 400) is widely used in mining, construction, and heavy machinery industries due to its excellent wear resistance and toughness. In China, the most popular grades of wear-resistant steel at this hardness level are the NM-series and BW-series, which are engineered for severe abrasion environments.
1. NM-Series Wear-Resistant Steel
Characteristics:
High hardness: NM-series steel typically reaches 400 HB, providing excellent surface wear resistance.
Good toughness: Despite its hardness, NM steel maintains sufficient impact resistance for heavy-duty applications.
Alloy composition: Includes controlled amounts of carbon, manganese, chromium, and molybdenum to enhance wear resistance and strength.
Versatility: Can be cut, welded, and fabricated into plates, liners, or machine parts.
Applications:
Mining equipment: crusher jaws, grinding liners, hoppers, and chutes.
Material handling: conveyor belts, wear plates, and earthmoving equipment.
Construction machinery: bulldozer blades and excavator buckets.
2. BW-Series Wear-Resistant Steel
Characteristics:
Uniform hardness: BW-series steels provide a consistent 400 HB hardness throughout the thickness, ensuring long service life.
Enhanced abrasion resistance: Optimized for sliding and impact wear environments.
Good weldability: Can be fabricated with standard welding methods without significant loss of hardness.
Chemical composition: Alloyed with carbon, manganese, and chromium to provide a balance of hardness and toughness.
Applications:
Heavy mining machinery: bucket liners, crusher plates, impact hammers.
Industrial machinery: slurry pumps, mixing blades, and high-wear surfaces.
Transport equipment: hoppers, chutes, and conveyor liners handling abrasive materials.
3. Why Choose NM and BW Series for 400 Brinell Steel ApplicationsHigh abrasion resistance in extreme wear conditions.
Durable and long-lasting, reducing maintenance and replacement frequency.
Good impact toughness, suitable for moderate impact loads.
Versatile fabrication, including welding, cutting, and bending for custom applications.
Both series are engineered to meet the rigorous demands of mining, construction, cement, and material handling industries.
