CHROMAX Plate is manufactured by a unique process developed indigenously by which a heavy layer of highly wear resistant carbide is deposited on to a mild steel base. Very hard carbides are suspended in a tough wear resistant matrix. It is the concentration of the carbide structure that gives CHROMAX Plate its unique wear characteristics.

DESCRIPTION:

The bond between the mild steel base and the overlay is of a very high strength. It will resist repeated and prolonged impact loads and the overlay deposit offers unequalled resistance to low or high stress abrasion and elevated temperatures upto 700 ºC. Cold Abrasion tests carried out on CHROMAX Wear Resist Plate have shown a 30 to 1 improvement in wear resistance over mild steel. Hot abrasion tests have shown a 20 to 1 improvement over mild steel at 600 ºC in applications much as ore chutes in steel mills and 3 to 1 improvement over traditional hard facing and alloys such as innards, etc.

APPEARANCE:

The wear resisting side of CHROMAX Plate appears as about 35 mm smooth weld bands. These bands are fused together to form an essentially flat even continuous surface. Due to hard characteristics of the carbide layer and the contraction stresses during the manufacturing process, cracks develop at right angles to the surface but do not penetrate beyond the carbide layer. These cracks are essential to the stress relieving process.
