400 Baja HB

400 Baja HB

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

Ketika AR400 is suitable for general wear applications, BW400 and NM400 remain the preferred choice in abrasi tinggi, pertambangan, dan aplikasi industri, memastikan umur panjang, pengurangan pemeliharaan, and optimal performance.

Keterangan

400 baja HB is a widely used wear-resistant material in pertambangan, konstruksi, and heavy machinery industries. Popular grades include NM400, BW400, dan AR400, each designed to balance ketahanan terhadap abrasi, kekerasan, and industrial applicability.

1. Overview of NM400, BW400, dan AR400

Nilai	Kekerasan (HB)	Karakteristik Utama	Aplikasi
NM400	400 HB	High abrasion resistance with good toughness; ideal for impact + keausan geser	Lapisan penghancur, hopper, air terjun, liner ember
BW400	400 HB	Kekerasan seragam, ketahanan aus yang sangat baik, especially for heavy sliding wear; superior dimensional stability	Liner konveyor, peralatan pertambangan, large abrasion surfaces
AR400	400 HB	Quenched and tempered steel with balanced hardness and impact resistance	General wear plates, earthmoving machinery, peralatan konstruksi

2. Advantages of NM400 and BW400

NM400

Optimized alloy composition (C, Kr, M N) for high ketahanan terhadap abrasi dan benturan.
Berkinerja baik di combined impact and sliding wear environments.
Kemampuan las yang baik allows fabrication into customized components.
Biasa digunakan di mining crushers, liner penggilingan, dan hopper.

BW400

Uniform hardness throughout the plate thickness memastikan masa pakai lebih lama.
Ketahanan aus geser yang sangat baik, 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 unggul dalam combined impact and sliding wear, making it ideal for crushers and hoppers.
BW400 menyediakan maximum sliding wear resistance and dimensional stability, making it superior for large-scale conveyor systems and heavy mining equipment.
