400 ブリネル鋼
China’s NM-series and BW-series wear-resistant steels provide reliable 400 ブリネル硬さ with excellent abrasion resistance and toughness. These materials are ideal for heavy-duty industrial equipment where 着る, インパクト, そして長期的な耐久性 重要です. Selecting the appropriate series ensures extended service life, reduced downtime, and optimized operational efficiency.
- 説明
スチール製 400 ブリネル硬さ (HBW 400) is widely used in mining, 工事, and heavy machinery industries due to its excellent wear resistance and toughness. 中国では, the most popular grades of wear-resistant steel at this hardness level are the NM-series そして BW-series, which are engineered for severe abrasion environments.
1. NM-Series Wear-Resistant Steel
特徴:
-
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, マンガン, クロム, and molybdenum to enhance wear resistance and strength.
-
Versatility: カット可能, 溶接された, そしてプレートに加工されます, ライナー, or machine parts.
アプリケーション:
-
鉱山機械: crusher jaws, 研削ライナー, ホッパー, そしてシュート.
-
マテリアルハンドリング: conveyor belts, プレートを着用してください, and earthmoving equipment.
-
建設機械: bulldozer blades and excavator buckets.
2. BW-Series Wear-Resistant Steel
特徴:
-
均一な硬さ: 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.
-
化学組成: Alloyed with carbon, マンガン, and chromium to provide a balance of hardness and toughness.
アプリケーション:
-
Heavy mining machinery: バケットライナー, クラッシャープレート, impact hammers.
-
Industrial machinery: スラリーポンプ, mixing blades, and high-wear surfaces.
-
Transport equipment: ホッパー, 滝, and conveyor liners handling abrasive materials.
3. Why Choose NM and BW Series for 400 Brinell Steel Applications高い耐摩耗性 in extreme wear conditions.
-
Durable and long-lasting, reducing maintenance and replacement frequency.
-
Good impact toughness, suitable for moderate impact loads.
-
多用途な製造, including welding, 切断, and bending for custom applications.
Both series are engineered to meet the rigorous demands of 採掘, 工事, セメント, and material handling industries.
