Chromium Carbide Overlay Wear Resistant Bimetal Plate – Mining & Cement Grade
Product Overview
High chromium carbide (CCO) overlay wear plate is a heavy-duty bimetal composite material designed for severe abrasive wear applications. It consists of a tough carbon steel base layer for structural strength and a high-chromium white iron overlay layer for extreme abrasion resistance. Manufactured by open arc overlay welding, this grade delivers unmatched wear performance at a moderate cost, making it the standard material for mining, cement and bulk material handling equipment.
Why Choose CNB Wear Resistant Clad Plate?
Our wear resistant bimetal plates are manufactured on automated overlay welding lines with strict control over carbide distribution, hardness uniformity and overlay thickness. Every plate undergoes hardness testing and thickness verification to guarantee consistent wear performance. We offer standard flat plates and custom formed liners to match specific equipment geometries, helping customers extend equipment service life and reduce maintenance costs.
