What is a water quenched steel? Brands include: DURASTAT ABRO DILLIDUR RAEX HARDOX ABRAZO XAR
Our proposal is to offer alternative grades widely used across Europe & ROW:Low carbon alloy with Mn, Si, Cr, Mo, Ni, Ti Hardness intentionally limited at delivery stage Hardening effect occurring under impact and/or pressure Can be profiled using all standard processes Can be rolled & bent Easier to drill, machine, countersink… Possible to fix
*rate of capacity to work with 1 up to 5 (5= easiest ) °grades normally impossible to classify in the anti-abrasion rang nevertheless used as the ultimate solution at high T°. If maintained for long periods at T° 650/950°C be aware of the risk of structure degradation ( sigma phase= brittleness)
OK, so they are the technical aspects of the various options to resist the wear phenomenon. How is CREUSABRO successful in real life environments?
Case study N°1 in chromium quarry, Turkey:The tested CREUSABRO8000against the industry standard water quenched grade 450 HB
The results of the two tests show a strong wear lifetime difference, which deserves a mention Wheel Loader N°1 Chromite stock area CREUSABRO8000 549 h WQ 450 HB 454 h (549 - 454) / 454 = % 21 + life time Wheel Loader N°2 Ferrochrome stock area CREUSABRO8000 605 h WQ 450 HB 315 h (605 - 315) / 315 = % 92 + life time Chromite Density:4.1 - 4.9 Hardness:5.5 mohs Grain size:15 / 60 mm Ferrochrome Density:7.2 Hardness:7 - 8 mohs Grain size: 200 / 500 mm • In both cases the lifetime differences are mainly linked to the energy of impact, • which is strongly depending on the following factors: • Material density (Stone & Alloy), which has a strong influence on the impact energy level • Grain size, which offers a significant increase in impact energy

At present we supply: • EON (Germany) • ENEL (Italy) • EDF (France) • Various in Turkey • and others across Europe • for more than 10 years • with CREUSABRO4800heat resistance < 450 °C WQ grade cannot work above 250 °C
Case Study N°3 LIEBHERR (OEM - ER 994 B – 771/ 14755)Application: kit wear parts for heavy duty buckets XXL Field test: CREUSABRO8000versus WQ 500 HB steel from North Europe
(3700 - 2540) / 2540 = + 46 % in favour of CREUSABRO 8000 — Bucket Equipped with water quenched 500 HB — Bucket Equipped with CREUSABRO8000 Inspected and cleared for use at 2600 hours Test stopped at 3700 hours with no issues Maintenance needed after 2540 hours
Original bucket equipped with WQ 500 HB maintenance needed after 2540 hoursBucket equipped with CREUSABRO 8000inspected and cleared for use at 2600 hours. Test stopped at 3700 hours with no issues (3700 - 2540) / 2540 = + 46 % in favor of CREUSABRO 8000
Test N°4 Cement plant Holcim (GY) We have succeeded with CREUSABRO8000against cast Iron (Cr alloyed)
Liners for a crusher with dynamic separator Casting pieces thickness = 50 mm CREUSABRO 8000 thickness = 50 mm
At present we supply CREUSABROto: • Cemex (UK & Germany) • LaFarge (Italy, France, US, etc) • Holcim (Germany) • Polysius (Germany) • Primarily for wear and heat resistance.
Changing to CREUSABRO 8000 the customer has increased the lifetime of the cast parts from 12 to 30 months
