Bulk 2013

A diverse selection of materials & hardness values are available to fight against the wear phenomena

Hardness HB HV HRC

Ceramic frit - 1600 / 2500 -

Nitriding steel - 850 / 950 67

Case hardened steel - 780 62 / 64

Overlay (Cr cast iron) - 760 60 / 62

Cr (20 / 25 %) cast iron - 840 60 / 65

White cast iron 570 600 55

Wear resistant steel 500 / 540 570 54

When you have to process these options, it’s another game

Ability to:

2Flame cut?

2Weld?

2Roll & bend?

2Drill, machine & tap?

2Install and repair?

What is a water quenched steel?

Brands include:

ABRO

ABRAZO

DILLIDUR

RAEX

DURASTAT

XAR

HARDOX

Our proposal is to offer alternative grades widely used across Europe & ROW:Low carbon alloy with Mn, Si, Cr, Mo, Ni, Ti

2 Hardness intentionally limited at delivery stage

2 Hardening effect occurring under impact and/or pressure

2 Can be profiled using all standard processes

2 Can be rolled & bent

2 Easier to drill, machine, countersink…

2 Possible to fix

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 hWQ 450 HB 454 h(549 - 454) / 454 = % 21 + life time

Wheel Loader N°2 Ferrochrome stock area

CREUSABRO 8000 605 hWQ 450 HB 315 h(605 - 315) / 315 = % 92 + life time

ChromiteDensity: 4.1 - 4.9 Hardness: 5.5 mohsGrain size: 15 / 60 mm

FerrochromeDensity: 7.2 Hardness: 7 - 8 mohsGrain 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:

2Material density (Stone & Alloy), which has a strong influence on the impact energy level

2Grain size, which offers a significant increase in impact energy

Case Study N°2 Coal fired power station

2 Reduction from square to round

2 Square pipe to handle coal powder

Elbows to handle coal powder just upstream burner
