400 Acciaio Brinell
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, impatto, and long-term durability sono critici. Selecting the appropriate series ensures extended service life, reduced downtime, and optimized operational efficiency.
- Descrizione
Steel with 400 Brinell hardness (HBW 400) is widely used in mining, costruzione, and heavy machinery industries due to its excellent wear resistance and toughness. In Cina, the most popular grades of wear-resistant steel at this hardness level are the NM-series E BW-series, which are engineered for severe abrasion environments.
1. NM-Series Wear-Resistant Steel
Caratteristiche:
-
Elevata durezza: 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.
-
Composizione della lega: Includes controlled amounts of carbon, manganese, cromo, and molybdenum to enhance wear resistance and strength.
-
Versatilità: Può essere tagliato, saldato, and fabricated into plates, fodere, or machine parts.
Applicazioni:
-
Attrezzature minerarie: crusher jaws, rivestimenti di macinazione, tramogge, e scivoli.
-
Movimentazione dei materiali: conveyor belts, piastre di usura, and earthmoving equipment.
-
Macchine edili: bulldozer blades and excavator buckets.
2. BW-Series Wear-Resistant Steel
Caratteristiche:
-
Durezza uniforme: 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.
-
Buona saldabilità: Can be fabricated with standard welding methods without significant loss of hardness.
-
Composizione chimica: Alloyed with carbon, manganese, and chromium to provide a balance of hardness and toughness.
Applicazioni:
-
Heavy mining machinery: fodera per secchi, crusher plates, martelli da impatto.
-
Industrial machinery: pompe per liquami, mixing blades, and high-wear surfaces.
-
Transport equipment: tramogge, cade, and conveyor liners handling abrasive materials.
3. Why Choose NM and BW Series for 400 Brinell Steel ApplicationsElevata resistenza all'abrasione in extreme wear conditions.
-
Durable and long-lasting, reducing maintenance and replacement frequency.
-
Good impact toughness, suitable for moderate impact loads.
-
Fabbricazione versatile, including welding, taglio, and bending for custom applications.
Both series are engineered to meet the rigorous demands of minerario, costruzione, cemento, e industrie di movimentazione dei materiali.
