RAEX300/400/450/500 Wear Resistance Steel Sheet
Raex is a high-strength, wear-resistant steel with favorable hardness and impact toughness. It can help extend the lifespan of machinery, decrease wear in structural components and save costs. It also enables innovative design and lightweight products improving energy efficiency. Applications include buckets and containers, cutting edges for earthmoving machines, wearing parts for mining machines, wearing parts for concrete mixing plants and wood processing machines, platform structures, and feeders and funnels. The most common grade of Raex wear-resistant is Raex 300, Raex400, Raex 450, Raex 500

- Maximum width of a cut length and heavy plate depends on the thickness and steel grade.
- Cut lengths with lengths 12-13 metres and plates with lengths 12-16 metres are available subject to special agreement.
- In thicknesses of 40.01 – 80 mm the maximum plate weight is 10 tons instead of 11 tons which is possible for thicknesses < 40 mm.
- In case of 2000 – <4000 mm of minimum length, two plates is the minimum amount to be ordered.
