Overlay Wear Plates

ZK series plate is available in a range of thickness and a choice of overlay material and backing palte combinations with either a single layer or a double pass overlay depending on the application and overlay thickness requirement. ZK overlays are deposited using an open arc process which is distinguished by a wide and smooth bead shape with a clearly defined and well developed pattern of superficial stress cracks.

The microstructure of the ZK plate overlay is a mixture of high volumes of hexagonal shaped Chromium Carbides in a tough matrix of austenite and martensite.

Chemical Composition & Hardness
Grade	C%	Cr%	Others	Hardness	Appliction
ZK-X	3.5	20	Mn Si Fe	650-750HV	High abrasion, moderate impact
ZK-N	3.5	20	Nb Mn Si Fe	700-800HV	Severe sliding abrasion and fine particle abrasion with low impact
ZK-H	3.5	20	Nb Mn Si V Mo W Fe	750-850HV	Severe sliding abrasion with high temperature
ZK-I	3.5	20	Nb Mn Si Fe	550-650HV	High abrasion and high impact
Other alloys may be added to enhance properities and extend performance.

ZK plates have an anti abrasion resistance of 10-15 times compared to an SS400 steel plate. It is available in the following standard sizes.
