Hardax 400, 450, and 500 are high-performance abrasion-resistant (AR) steel plates specially designed to deliver exceptional durability, impact resistance, and extended service life in aggressive wear environments. These plates are engineered to withstand intense wear and tear, reducing maintenance costs and increasing the productivity of heavy-duty industrial machinery.
With a balance of toughness, hardness, and workability, Hardax AR plates are widely used across industries like mining, quarrying, construction, cement, earthmoving, recycling, and material handling.
Grade | Nominal Hardness (HBW) | Key Characteristics | Common Applications |
---|---|---|---|
Hardax 400 | 400 | Excellent combination of wear resistance and formability | Tipper bodies, liners, loaders, dozer blades |
Hardax 450 | 450 | Higher hardness with superior impact resistance | Excavator buckets, dump truck beds, hoppers |
Hardax 500 | 500 | Maximum wear resistance for the most demanding applications | Chutes, crushers, cutting edges, shredder components |
Consistent hardness and wear resistance
Superior impact strength, even at low temperatures
Excellent formability and weldability
Longer wear life, reducing downtime and replacement costs
High surface finish quality, suitable for precision applications
