- CHROMAX PLATE has hardness range of 55 to 65 HRC (Rockwell C Scale) depending on grade. Hardness is uniform throughout the overlay thickness.
- CHROMAX PLATE consists of up to 60% by volume of Chromium rich carbides in an Iron matrix.
- CHROMAX PLATE offers unparalleled resistance to high stress abrasion and prolonged impact loading at a high temperature up to 700ºC.
- Cold abrasion tests have shown an improvement in wear resistance at 30 times that of mild steel. 3 to 1 improvement over traditional wear resistant materials such as Ni-Hard. Normal conditions show 12 to 1 improvement over heat treated Manganese Steel Hot abrasion tests have shown 20 to 1 improvement over mild steel.
CHROMAX wear plate by DEMECH is a composite plate, manufactured by a unique process in which a uniform layer of highly wear resistant carbides is deposited on a carbon steel base. Very hard carbides are suspended in a tough wear resistant matrix. It is the concentration and uniform distribution of carbide structure that gives CHROMAX wear plate its unique wear resistant and life prolonging characteristics.
The process involves applying specially and accurately blended powders to the area to be overlaid by forming an arc, and covering the arc by flux which avoids the oxidation of the deposits.
The bond between the mild steel base and the overlay is of very high strength and resists repeated and prolonged impact loads and the overlaid deposit offers inequable resistance to low and high stress abrasion.
CHROMAX wear plate is very cost effective giving extremely long life reducing maintenance, downtime, increasing productivity and efficiency, hence extensively used for sinter screens, chute liners, hoppers, mill liners etc.
