Scope
RAEX™ is a high strength and wear resistant steel with favourable hardness and impact toughness. With RAEX you can extend the lifespan of machinery, decrease wear in structural components and save costs. It also enables innovative design and lightweight products improving energy efficiency.
Application
Buckets and containers, cutting edges for earth moving machines, wearing parts for mining machines, wearing parts for concrete mixing plants and wood processing machines, platform structures, feeders and funnels.
Tolerances

In addition, aluminium (Al), niobium (Nb), vanadium (V) and/or titanium (Ti) can be used as micro-alloy material.
Supply Condition:
Hardened.
Abrasion Resistance & Hardness:
The microstructure of abrasion resistant steel is martensitic, which guarantees high hardness and tensile strength. High hardness and tensile strength give a steel high resistance to abrasion.
