Industry White Paper & Technical Analysis
In heavy-duty manufacturing and raw material processing, material degradation represents one of the largest drains on global industrial profitability. Traditional carbon steel and simple low-alloy matrices deteriorate rapidly under the constant mechanical action of sliding friction, high-stress grinding, and impact abrasion. Under the categorization of Cemented Carbide systems, advanced wear-resistant coatings, structural overlays, and customized chromium carbide bimetallic materials have emerged as the standard approach for longevity.
According to global industrial studies, wear-related downtime accounts for billions of dollars of lost production capacity annually. To counter these challenges, operators in key sectors—such as cement production, open-cast mining, iron and steel smelting, waste-to-energy power plants, and bulk cargo ports—are transitioning from standard structural steel plates to engineered Chromium Carbide Overlays (CCO). These composite materials combine a ductile backing plate (typically standard structural steel) with an extremely hard, carbide-rich overlay, delivering optimal toughness and wear resilience.
The performance of hardfaced wear assemblies depends on their microstructural layout. The primary wear resistance in Runxing CCO plates and bimetallic components is provided by M7C3 primary chromium carbides. During the weld deposition process, chromium and carbon precipitate from the molten pool to form hexagonal-shaped chromium carbides embedded within a tough, hard matrix of martensite and austenite.
Key metallurgical factors that dictate performance include:
