Better than only hardness, CREUSABRO ® 4800 ℗ offer an exceptional upper wear resistance from + 40 up to 45 % compared with 400 HB, water quenched steel, maintaining in the same time an easier processing aptitude. Thanks to different chemical composition dedicated to each thickness range CREUSABRO ® 4800 ℗implements several metallurgical concepts which are more efficient than simple hardness:
The intentionally limited hardness of CREUSABRO ® 4800 ℗ at delivery condition facilitates in a significant proportion the different processing operations such as: cutting, machining and transformation (bending & rolling).
CREUSABRO ® 4800 ℗ is suitable against all types of abrasion phenomenon like sliding, impact, dry or wet environment, including high temperature (< 450℃ th < 20 mm) and (< 350 ℃ th > 20 mm) in continuous operating condition.

Other cutting parameters
CREUSABRO ® 4800 ℗ plasma cutting process is more advantageous than oxygen cutting considering the following points:
As with flame cutting, a preheating at 150 ℃ is required to cut plate thicknesses higher than 60 mm.
This solution is particularly adapted for cutting plate.
Operational capacities of current machines allow plates up to 20 mm to be cut.
Punching of CREUSABRO ® 4800 ℗ is possible for plate thickness up to about 12 mm max.
