Features of CREUSABRO steels
CREUSABRO steels differ from low-alloy, wear-resistant steels. By adding Cr and Mo for example, the sheets feature better temperature resistance compared to water-quenched and tempered HB steels. At operating temperatures up to 500 °C there is no significant loss of hardness. Consequently, the steel is perfectly suited for hot formability. Processing at 500 °C and subsequent air cooling does therefore not cause a massive loss of hardness.
The quenching rates used in the manufacturing process result in
- special material properties
- increased wear-resistance (A distinction is made between the following types of wear: for example sliding abrasion, impact wear, roller or drum wear)
- uniformly hardened sheets with low residual stresses.
* up to max. 25mm thickness
** up to max. 25mm thickness
Particularities of CREUSABRO Steel
CREUSABRO steels are manufactured in such a way that the wear-resistant sheets ensure good further processing (for example such as bevelling) due to the moderate hardness upon delivery. Hence processing with typical tools and cold production are possible. This results in lower production costs for the processor. Wear resistance under operating conditions is not affected. The so-called TRIP effect (transformation induced plasticity) increases the wear resistance by 70 HB of the steels during application, and it does so homogeneously throughout the entire sheet thickness. This metallurgical process is referred to as transformation induced plasticity. For example, this abrasion can be caused by the impact of stones or abrasion particles. CREUSABRO thus provides the perfect combination of wear resistance (excellent surface hardening under wear-and-tear strain) and easy processing for the toughest manufacturing and operating conditions.
Results with CREUSABRO steel
Many processors around the world have had great experiences with CREUSABRO sheets. The wear-resistant steel ensures longer service life of machines in
- the mining industry (including components for chain conveyors, mining and transport equipment)
- conveyor technology/materials handling
- recycling (including screens, shredder linings and tools)
- stones and soils (including jaw and impact crushers)
- cement plants, mills, separators (including rotor blades, armouring, mill linings)
- iron metallurgy (including fire truck linings, ash grates)
- many other industrial applications.
Advantages of CREUSABRO Steel
UnionStahl is exclusively using CREUSABRO 4800, CREUSABRO 8000 and CREUSABRO Dual sheet metals and is thus a strong partner for the iron metallurgy, mining, construction machinery and mechanical engineering industries.
By marketing CREUSABRO sheets we offer our customers the following benefits:
- Higher wear resistance compared to conventional water-quenched and tempered sheets
- The service life of CREUSABRO 4800 sheets is 50% higher compared to the traditional water-quenched and tempered 400 HB series
- CREUSABRO 8000 also features a 50% higher service life expectancy compared to traditional sheets of the 500 HB series
- Compared to traditional water-quenched and tempered wear-resistant steel, CREUSABRO sheets weigh less and can handle higher payloads with the same wear life. This makes lower sheet thickness possible.
- Avoidance of cost-intensive machine downtimes leads to savings in manufacturing and maintenance costs. It also provides considerable potential to reduce operating costs.
Guarantee and performance
guarantee a toughness of at least 32 J at -20 °C. Furthermore, the wear-resistant steel stands out with good weldability. This makes the sheets suitable for use in mining and dump truck structures, excavator shovels, heavy duty shears for scrap and other applications.
Due to the quenching process during production, the wear-resistant steel does not have any residual stresses. Consequently, no deformation occurs during and after cutting. An outstanding flatness of < 3 mm/m is achieved without further cold forming. The delivery condition of the material is soft in comparison to traditional water-quenched and tempered steels, without compromising the wear resistance under operating conditions. CREUSABRO steels are this perfectly suited for the manufacture of complex components.
are distinguished by their good temperature and wear resistance. Traditional water-quenched and tempered steels lose their hardness above 250 °C. By contrast, CREUSABRO steels can be used up to an operating temperature of 450 °C. This is the result of its chemical composition and the microstructure. It also features additional advantages like the reduced heat-affected zone, for example after flame cutting or welding. It also allows for hot forming without further heat treatment. This makes wear-resistant CREUSABRO sheets the perfect choice for industrial applications requiring high temperatures, such as the energy, cement, iron and steel industries.
Therefore, with CREUSABRO, UnionStahl offers you a unique, optimal and proven solution of wear-resistant steel for higher loads, higher temperatures, exceptional performance and greater resistance!
