Ability to:
Flame cut?
Weld?
Roll & bend?
Drill, machine & tap?
Install and repair?

6. 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

9. OK, so they are the technical aspects of the various options to resist the wear phenomenon.
How is CREUSABRO successful in real life environments?

10. Case study N°1 in chromium quarry, Turkey: The tested CREUSABRO 8000 against the industry standard water quenched grade 450 HB

11. The results of the two tests show a strong wear lifetime difference, which deserves a mention
Wheel Loader N°1 Chromite stock area
CREUSABRO h
WQ 450 HB 454 h
( ) / 454 = % 21 + life time
Wheel Loader N°2 Ferrochrome stock area
CREUSABRO h
WQ 450 HB 315 h
( ) / 315 = % 92 + life time
Chromite
Density:
Hardness: 5.5 mohs
Grain size: 15 / 60 mm
Ferrochrome
Density: 7.2
Hardness: 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

12. Case Study N°2 Coal fired power station

15. WQ grade cannot work above 250 °C
At present we supply:
EON (Germany)
ENEL (Italy)
EDF (France)
Various in Turkey
and others across Europe

19. Test N°4 Cement plant Holcim (GY)
We have succeeded with CREUSABRO 8000 against cast Iron (Cr alloyed)

20. Liners for a crusher with dynamic separator
Casting pieces
thickness = 50 mm
CREUSABRO 8000
thickness = 50 mm

21. At present we supply CREUSABRO to:
Cemex (UK & Germany)
LaFarge (Italy, France, US, etc)
Holcim (Germany)
Polysius (Germany)
Primarily for wear and heat resistance.

22. Changing to CREUSABRO 8000
the customer has increased
the lifetime of the cast parts
from 12 to 30 months

23. CREUSABRO Concept has found inspiration from 100 % Austenitic grade
