Creusabro® Unique, best, Proven Advanced technology in wear Creusabro® 4800 is a high performance wear resistant steel, exhibiting a wear resistance 50% higher than that of conventional 400HB water quenched steel. Rather than relying exclusively on a high hardness level, properties of Creusabro® 4800 are improved as a result of the combination of an enriched alloying content (chromium, nickel, molybdenum and titanium) and specific heat treatment procedures. Creusabro® 4800 is designed to offer the best possible optimization of an exceptional wear resistance and very acceptable workability.
The specific concept with controlled quenching rates used in the mill fabrication practice: – develop a bainite-martensite mixed microstructure with retained austenite absorbing impact; – stimulate a fine dispersion of hard micro-alloyed carbides delaying cracking and surface peel off; – wear resistance in service is strongly improved by a surface hardening effect of +70 HB under the action of local plastic deformations. This is known as TRIP-effect.
Longer service life by +50 to 100% Creusabro® 4800 outlasts classical 400HB-class plates by 50 -100% Alternatively, Creusabro® steels offer substantial weight savings and increased payload potential (lower thickness is required) for the same wear life as standard water quenched plates.
Structural capacity within a wear plate Creusabro® has a guaranteed impact energy of min 32 J at -20°C. It offers the toughness and weldability necessary to perform not just as a wear liner, but potentially as a structural material.
Workshop-friendly, – no residual stresses within the plate, thus no deformation during and after cutting, thanks to soft quenching process – excellent flatness < 5 mm/m achieved without cold-deformation – softer material in the as-delivery condition facilitate smooth and easy processing of complex parts at the workshop, without compromising on the wear resistance.
Heat and wear resistance Specific chemical composition and initial microstructure result in a high resistance to softening compared to conventional water quenched, which lose their hardness above 250°C. – in-service temperature up to 450°C – reduced Heat Affected Zone, e.g. after flame cutting or welding – if required, Creusabro plates can be hot formed at without any further heat treatment.

Creusabro® Unique, best, Proven Creusabro®Dual is an advanced abrasion-resistant steel with high titanium content (0.6%). This innovative grade is mainly dedicated to severe sliding wear conditions in service for applications where conventional water quenched steels (500HB, 550HB,600HB), overlay plates or hard-cast parts are traditionally implemented. Creusabro®Dual is exclusively produced by Oil Quenching, which reduces the level of the residual stresses encountered within the plate after heat treatment. The outstanding wear resistance against severe abrasion combined with high impact cycle load is mainly due to the contribution of the following hardening phenomena: – a homogeneous precipitation of extra hard primary titanium carbides (3000HV) in the steel matrix leading to a significant improvement of the sliding wear resistance in extreme service conditions. – a surface hardening obtained by a very efficient work hardening capability in service, governed by a metallurgic phenomenon called TRIP effect (Transformation Induced by Plasticity).
Longer service life by +50 to 100% Creusabro® Dual outlast by 50 -100% classical 500HB-class plates, overlay products, hard cast irons… Alternatively, Creusabro® steels offer substantial weight savings and increased payload potential (lower thickness is required) for the same wear life as standard water quenched plates.

12-14%Mn austenitic manganese hot rolled steel plate. Creusabro® M is the genuine fine-grained 12-14%Mn austenitic manganese steel (Hadfield steel) hot-rolled plate.
The outstanding strain hardening capacity of 12-14%Mn austenitic manganese steel has been recognized for a long time. In the delivery condition, Creusabro® M exhibits a moderate hardness in the range 180 – 240 HB combined to a high ductility and absorbed impact energy. When subjected to pressure or impact loads in service, Creusabro® M steel work hardens considerably on the surface up to 600 HB, while remaining not brittle in the bulk.
As a result, Creusabro® M exhibits high resistance to abrasive wear, where external conditions cause extensive work hardening of the wear component’s surface. Creusabro® M has found many applications in crushing and earthmoving equipment, in railways and in the shot blasting industry.
The second essential property is that 12-14%Mn austenitic manganese steel is a non-magnetic steel.
