Key Benefits
450 HBW nominal hardness provides excellent resistance against sliding and impact abrasion, helping extend component service life.
High yield and tensile strength allows thinner plate selection, reducing equipment weight and steel consumption.
Good weldability simplifies fabrication using standard low-hydrogen welding procedures.
Wide thickness range supports procurement for both light-duty liners and heavy structural wear components.
Typical Applications
- Dump truck bodies
- Excavator buckets
- Wheel loader buckets
- Crusher liners
- Chutes and hoppers
- Conveyor transfer liners
