Abrasive resistant weldable steel plates have an excellent combination of hardness, abrasion resistance, formability, weldability, toughness and flatness to meet fabrication demands and application requirements. Designed for through- hardness, ARCELOR 400 has relatively low carbon equivalent for superior weldability and is supplied in quenched and tempered condition. The specially designed tempering cycle renders formability with minimal effect on hardness. ARCELOR 400 is suitable for yellow goods application in mining and construction markets such as crushers, body liners for truck beds, buckets, hoppers, chutes, excavators and conveyor troughs. Concrete mixer drums, trash truck bottoms, bucket lips, street sweepers and dump trailers are among other applications.

Choosing ARCELOR 400 (Nippon Steel Make In India)
ARCELOR 400 (Nippon Steel Make In India) is in the 400 HBW hardness class. Higher hardness generally lasts longer against sliding abrasion but is harder to bend, cut and weld; where parts also take heavy impact, a tougher, lower class can last longer.
| Class | Nominal hardness | Typical use | Forming and welding |
|---|---|---|---|
| 400 (this page) | About 400 HBW | Dumper bodies, chutes, hoppers, screens | Cold bending and welding with normal care |
| 450 | About 450 HBW | Buckets, liners and heavier wear parts | Larger bending radii; preheat thicker sections |
| 500 | About 500 HBW | Cutting edges, crusher and severe-abrasion liners | Limited forming; strict cutting and welding procedures |
Other ARCELOR classes
Brands of the same class are comparable, not identical; confirm any substitution with the end user. See all brands on Wear Resistant Plates.
Applications for ARCELOR 400 (Nippon Steel Make In India)
Typical uses include crushers, truck-bed liners, buckets, hoppers, chutes and conveyor troughs. Tell us the abrasive material, impact level and the life of the current part so the right class can be quoted.
Cutting, Fabrication and Welding
Champak Industries describes full and part plate/profile supply and a plasma-cutting service. Thermal cutting softens a narrow edge zone, and thick or hard plate may need preheat before cutting. Weld with low-hydrogen consumables and the mill’s preheat and interpass limits; do not heat the plate above the mill’s tempering limit. See AR Plates for bending and drilling guidance.
Testing, Inspection Documents and Traceability
| Requirement | What to identify in the order |
|---|---|
| Mill test certificate | EN 10204 3.1 showing brand and grade, heat number, chemistry and hardness |
| Impact test | Charpy test temperature and minimum energy, if required |
| Traceability | Heat and plate number transferred to cut pieces |
