AR400 is an abrasion‑resistant steel plate tailored for working scenarios where steel parts keep coming into contact with abrasive substances.
Against ordinary structural steel grades, AR400 delivers much stronger surface wear performance. That is why it is widely adopted for parts processing rock, ore, sand, gravel, coal and other abrasive bulk materials.
The figure “400” in its grade name stands for its typical Brinell hardness of around 400 HBW.
For purchasers, the core benefit lies in extended part service life and fewer part replacements under tough operating conditions.
Click the Button on The Right
1. Superior Abrasion Resistance
AR400 wear resistant steel is purpose-built to endure constant friction and scouring caused by hard, abrasive raw materials. It is a preferred material for manufacturing wear liners, truck dump bodies, chutes, hoppers and various custom mining equipment that faces long-term material abrasion.
2. Reliable High Hardness
Featuring a standard Brinell hardness of 400 HBW, AR400 steel delivers outstanding resistance to surface scratching, denting and material thinning, effectively coping with harsh wear working conditions.
3. Longer Equipment Service Lifespan
Adopting AR400 steel for high-wear vulnerable parts greatly cuts down routine maintenance and part replacement frequency. It significantly prolongs the overall service life of industrial and mining equipment, reducing long-term operational downtime.
4. Optimized Strength-to-Weight Ratio
Thanks to its premium hardness and structural strength, AR400 enables manufacturers to adopt thinner plate designs for eligible working scenarios. This design solution maintains stable wear resistance and structural performance while lowering overall equipment weight and production costs.
5. Flexible Processing & Fabrication Performance
AR400 steel plate boasts excellent processability. In accordance with plate thickness, processing equipment and actual project demands, it can be freely cut, drilled, welded and cold-formed with standard professional construction procedures, supporting diverse custom fabrication needs.
| Feature | AR400 Wear Plate | Conventional Carbon Steel |
| Wear Resistance | Excellent | Moderate |
| Hardness | Approx. 400 HBW | Generally lower |
| Abrasion Resistance | High | Limited |
| Service Life in Abrasive Conditions | Long | Relatively short |
| Typical Use | Mining, quarrying, heavy equipment | General structures and fabrication |
| Replacement Frequency | Lower in wear applications | Higher in severe abrasion |
| Main Advantage | Resistance to abrasion | General fabrication and structural use |
AR400 steel sees extensive use across heavy‑duty operations, where abrasive wear poses one of the biggest operational challenges.

1. Is AR400 the same as ASTM A606 Type 4?
Not exactly. AR400 is a widely‑recognized grade for abrasion‑resistant steel. ASTM A606 Type 4, by contrast, covers high‑strength low‑alloy steel designed for atmospheric corrosion resistance. These two materials cannot be treated as interchangeable unless supported by official material test reports.
2. What does AR400 stand for?
AR400 refers to abrasion‑resistant steel featuring a typical Brinell hardness of around 400 HBW. Its precise chemical makeup and mechanical properties follow each producer’s technical data or relevant material standards.
3. What are typical applications for AR400 steel?
AR400 steel finds broad use across heavy‑duty wear‑prone parts: mining machinery, crusher components, excavator buckets, dump truck beds, hoppers, chutes, conveyor systems and quarry processing equipment.
4. Is AR400 weldable?
AR400 is weldable in most cases. However, its high hardness and carbon equivalent demand careful welding practice. Preheat temperature, interpass temperature, filler metal selection and heat input shall be adjusted according to actual plate grade and thickness.
5. Can you cut and drill AR400 steel?
Yes. Plasma cutting, flame cutting and other qualified cutting processes work for AR400. For drilling operations, tooling and operating parameters need to be selected specifically for hard wear‑resistant steel.
