For wear and tear which is not only caused by impact and friction, we provide CREUSABRO 4800 and CREUSABRO 8000. These products have TRIP (Transformation Induced by Plasticity) character and micro carbides that make this product have an active surface resistance, so that this material can last better if there is an impact. This product o can also be used in medium temperature 250–450 C, where other resistance product which generates from water quenched process usually will not be functioning optimally.
The new Creusabro concept-excellent ability to work harden and contribution of micro carbides-gives Creusabro 4000 high wear resistance, on average 4 times higher than ordinary mild steel and 30 % higher than conventional 4000 BHN water quenched steel.
To ease in fabricating, Creusabro 4000 is supplied by approximately 360 HB hardness. After the fabrication, the hardness of Creusabro 4000 can be reach 420 HB.

The Creusabro concept-excellent ability to work harden and the supplementary contribution of microcarbides, already used in Creusabro 4000 has been improved in the Creusabro 8000. this grade takes advantage of an additional metal working process: the TRIP effect (Transformation Induce by Plasticity). The combination of this properties give to the Creusabro 8000 an exceptional wear resistance in heavy plates with uniform properties throughout the thickness around 8 times that of the standard mild steel (A572 G65 grade). The properties in extreme conditions are 50% superior to standard water quenched steel (hardness 500HB).
Creusabro 8000 is supplied with the hardness of 420 HB in order to easy the fabrication. After fabrication, the hardness of Creusabro 8000 can reach 540 HB.
