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

the wear phenomenon.
How is CREUSABRO successful in real life environments?
Case study N°1 in chromium quarry, Turkey:
The tested CREUSABRO 8000 against
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
CREUSABRO 8000
549 h
WQ 450 HB
454 h
(549 - 454) / 454 = % 21 + life time
Chromite
Density: 4.1 - 4.9
Hardness: 5.5 mohs
Grain size: 15 / 60 mm
Wheel Loader N°2 Ferrochrome stock area
CREUSABRO 8000
605 h
WQ 450 HB
315 h
(605 - 315) / 315 = % 92 + life time
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
