400 HB鋼

400 HB鋼

Among 400 HB steels, BW400 and NM400 offer clear advantages for heavy-duty wear environments:

BW400: superior sliding wear resistance and dimensional stability
NM400: excellent impact + sliding wear balance with good weldability

その間 AR400 is suitable for general wear applications, BW400 and NM400 remain the preferred choice in high-abrasion, 採掘, および産業用途, 確保する long service life, reduced maintenance, and optimal performance.

説明

400 HB鋼 is a widely used wear-resistant material in 採掘, 工事, and heavy machinery industries. Popular grades include NM400, BW400, そしてAR400, each designed to balance 耐摩耗性, 靭性, and industrial applicability.

1. Overview of NM400, BW400, そしてAR400

学年	硬度 (HB)	主な特徴	アプリケーション
NM400	400 HB	High abrasion resistance with good toughness; ideal for impact + sliding wear	クラッシャーライナー, ホッパー, 滝, バケットライナー
BW400	400 HB	均一な硬さ, 優れた耐摩耗性, especially for heavy sliding wear; superior dimensional stability	コンベヤライナー, 鉱山機械, large abrasion surfaces
AR400	400 HB	Quenched and tempered steel with balanced hardness and impact resistance	General wear plates, earthmoving machinery, construction equipment

2. Advantages of NM400 and BW400

NM400

Optimized alloy composition (C, Cr, ん) for high abrasion and impact resistance.
Performs well in combined impact and sliding wear environments.
Good weldability allows fabrication into customized components.
一般的に使用されるのは、 mining crushers, 研削ライナー, とホッパー.

BW400

Uniform hardness throughout the plate thickness 保証します より長い耐用年数.
Excellent sliding wear resistance, suitable for heavy-duty conveyor liners and chutes.
Superior dimensional stability, reducing deformation during fabrication or installation.
Performs well under continuous abrasive conditions where NM400 may experience slight surface wear over time.

3. Comparison Summary

AR400 is versatile but slightly less specialized in high-abrasion scenarios.
NM400 excels in combined impact and sliding wear, making it ideal for crushers and hoppers.
BW400 提供します maximum sliding wear resistance and dimensional stability, making it superior for large-scale conveyor systems and heavy mining equipment.
