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.
