Chromium Carbide Overlay Wear/Abrasion Resistant Clad Hardfacing Bimetal Cco Plates

HART Plate is manufactured by depositing chromium-rich, abrasion-resistant materials on mild steel base plate using a traditional arc welding process. This product is usually referred to as chromium carbide overlay (CCO) plate on the market.The hardfacing overlay is suitable for severe abrasive wear and impact applications.Qingdao HART
Industrial Technology Co.,Ltd was established in 2003, it had a long history of providing innovative wear solution and world class wear products.The ultimate hardfaced product for your application depends on the material--whether rock, sand, gravel or other substance--striking or sliding along the surface of your wear part. It also depends on the angle and speed of impact as well as the operating temperature.
