Quenched and Tempered (Q&T) Alloy Steel Plate
Quenched and tempered (Q&T) alloy steel plates are manufactured to provide an optimal combination of hardness and strength, essential qualities for applications where strong impacts and significant wear are expected.
AR500 Q&T Wear-Resistant Steel Plate
AR500 Q&T (Quenched & Tempered) steel is a heat-treated wear-resistant steel plate with hardness above 500 HB (Brinell hardness). It is ideal for applications that require extreme resistance to wear, abrasion, and impact, while maintaining excellent toughness and performance under dynamic loads.
- High wear-resistant steel plate, heat-treated through quenching and tempering to optimize hardness and toughness.
- Hardness in the 500 HB (Brinell hardness) range.
- High resistance to wear, friction, and dynamic loads—ideal for severe operating conditions.
- Excellent balance between surface hardness and internal strength for durability and long service life.
- Despite its high hardness, it can be processed by cutting, welding, and forming without compromising mechanical properties.
- Ideal for industrial equipment exposed to extreme abrasion and intense working conditions.
- Extreme wear resistance: hardness above 500 HB helps withstand severe abrasion and wear, extending service life.
- High impact resistance: maintains excellent performance under dynamic loads and impacts.
- Longer component life: improves durability, reduces downtime, and lowers operating costs.
- Processing versatility: suitable for cutting, welding, and forming for many industrial applications.
- Mining: liners and components exposed to severe wear (crushers, mills, drilling/excavation wear parts).
- Construction: heavy equipment parts requiring extreme wear resistance (buckets, excavator teeth, shovels, material-handling tools).
- Bulk material handling: conveyors, augers/screws, loaders, and abrasive bulk handling systems.
- Agriculture: cutting blades, planter teeth, and tools exposed to severe abrasion.
- Energy: parts for power generation equipment and turbines requiring high wear resistance under extreme operation.
