In modern high-output industrial ecosystems, mechanical wear represents one of the most critical threats to process efficiency, operational uptime, and bottom-line profitability. Heavy sectors such as cement production, mining extraction, steel manufacturing, fossil power generation, and bulk material port logistics face continuous system-wide degradation from high-stress sliding abrasion, severe impact forces, and chemical erosive mechanisms. The search for superior wear plate solutions has shifted from standard carbon steel alloys to highly engineered composite materials, notably Chromium Carbide Overlay (CCO) bimetallic plates.
As a leading wear plate manufacturer and technological pioneer, Tangshan Runxing Machinery Co., Ltd. presents this industrial blueprint to detail the chemical structures, engineering integrations, and procurement strategies necessary to extend equipment lifecycle up to ten-fold compared to conventional structural steels.
Unlike standard alloy steels that rely on through-hardening heat treatments, bimetallic CCO plates are manufactured via an arc cladding process. A structural backing plate (typically ASTM A36 or Q235B steel) is clad with a layer of chromium-rich alloy. The resulting microstructure features primary chromium carbides (M7C3) with a hardness exceeding 1500 HV dispersed in a tough, eutectic matrix. The macro hardness of the overlay layer averages 58 to 65 HRC, ensuring extreme resistance against hard mineral sliding abrasion.
From wear plates to high-precision robotic cladding systems, we provide comprehensive industrial surface solutions.
