Chromium Carbide Overlay (CCO) wear plates, such as the RX®wp 7600, are composite materials. The process involves cladding a base structural steel sheet (e.g. low-carbon steel Q235B or ASTM A36) with a hypereutectic chromium alloy using open-arc or submerged arc cladding technology. During this process, carbon and chromium bond in the weld puddle to form primary M7C3 carbides, which reach a hardness of 1500 to 2000 HV (Vickers scale).
The wear resistance is dictated by the volume fraction of these primary carbides. In high-quality CCO sheets, the carbide volume fraction exceeds 30%, evenly distributed in a tough eutectic matrix. The soft backing steel absorbs impact loads and allows structural welding and forming, while the overlay handles aggressive, abrasive wear profiles.
The wear plate industry is shifting from standard binary alloys to complex alloy systems. In modern industrial operations, pure abrasion is often paired with mechanical impact and extreme heat. Tangshan Runxing Machinery Co., Ltd. is continually expanding material capabilities in several key areas:
Adding Nb forms tiny, tough niobium carbides (NbC) alongside M7C3. This refines grain boundaries and increases impact resistance without lowering bulk hardness.
By adjusting chromium, manganese, and silicon balances, these plates maintain their hardness at temperatures up to 600°C (1112°F)—ideal for sintering and cement kiln outlets.
Using Plasma Transferred Arc (PTA) technologies to apply thinner overlays with minimal dilution, reducing overall weight while maintaining extreme surface protection.
Founded in 2010, Tangshan Runxing Machinery Co., Ltd. operates a high-capacity manufacturing base in Tangshan, Hebei Province—the heart of China's metallurgy and raw materials hub. Integrating CNC automated cladding setups, Runxing provides consistent quality with rapid delivery timelines. Standard sheets are produced using 4-gun automated systems that monitor weld overlays to limit thermal warping and keep dilutions low.

Tangshan Runxing Machinery Co., Ltd., a professional manufacturer located in Tangshan, Hebei Province that focuses on R&D, production and on-site construction service of hardfacing wear-resistant metal products, was founded in 2010.
Our main products include chromium carbide overlay (CCO) wear plates, custom processed wear liners, wear-resistant pipes and pipe fittings, hardfacing flux-cored welding wires, automatic hardfacing welding machines, and professional roller surfacing repair service. We follow the business idea of “Integrity, Superior Quality, Innovation & Sustainable Development” and own mature advanced metal surface hardfacing technology.
We provide customized wear-resistant solutions for cement, steel, mining, port and dredging industries around the world, and have gained good market reputation in Russia and Central Asia. All export business is fully authorized and handled by Hebei Yuwan International Trade Co., Ltd. This trading company completes all export work including customs clearance, shipment, documents and payment collection. Our factory focuses on product development and production to ensure stable product quality and on-time delivery.

The www.runxing-machinery.com website has officially entered its trial operation phase. Built by Tangshan Runxing Machinery Co., Ltd., it serves as a platform offering one-stop procurement and support for the global wear-resistant industry.
From September 2 to 6, 2024, the South Africa International Construction Machinery, Mining Machinery, and Power & Energy Equipment Exhibition opened in Johannesburg, where Runxing showcased its latest CCO solutions.
In 2023, Yuan Shaoqiang (Dean of Tangshan University), Li Jing (Vice Dean), and Professor Yang Yuehui (Team Leader of Metal Materials) visited Runxing for cooperative research on metal forming technologies.
Since its establishment, Tangshan Runxing has used VAUTID welding materials to build high-performance overlay structures. Runxing has been a qualified agent for VAUTID since 2019.
From April 24 to 27, 2023, Runxing Machinery participated in EXPOMIN 2023 in Chile, the world's second-largest professional mining exhibition, displaying wear liners, pipes, and weld components.
Runxing CCO plates utilize hypereutectic alloys rich in primary M7C3 chromium carbides. These carbides are oriented perpendicular to the wear surface, offering exceptional resistance to sliding abrasion. The carbon steel backing absorbs impact, allowing the plate to be bolted, welded, or formed.
Yes. The structural backing plate (usually carbon steel) can be welded to existing structures using conventional low-hydrogen electrodes. Additionally, CCO plates can be cold-formed or rolled into curves (with the overlay on the inside or outside) to line cylindrical surfaces.
To ensure efficiency, Hebei Yuwan International Trade Co., Ltd. handles all export business for Runxing. They manage customs clearance, ocean shipping, banking transactions, and export documentation, while our Tangshan factory focuses on product quality, raw materials, and custom fabrication.
