Learn More >Founded in 2010 in the heavy industrial heartland of Tangshan, Hebei Province, Tangshan Runxing Machinery Co., Ltd. has grown to become a premier designer and manufacturer of hardfacing wear-resistant metal products. Our operations focus heavily on the research, development, and on-site integration of heavy industrial surfacing technologies.
Our core product line is engineered to address the destructive forces of abrasion, impact, heat, and corrosion. We specialize in producing premium Chromium Carbide Overlay (CCO) wear plates, customized wear liners, hardfacing flux-cored welding wires, automated overlay cladding machines, and professional roll rebuilding services. Grounded in our operating principle of “Integrity, Superior Quality, Innovation & Sustainable Development,” we utilize mature, advanced metallurgical cladding processes to optimize the operating lifespan of key processing systems globally.
To ensure global compliance, Hebei Yuwan International Trade Co., Ltd. is the fully authorized trading partner handling all international operations. From customs clearance, shipment preparation, and export documentation to financial collections, this structure allows our manufacturing team in Tangshan to focus entirely on quality control, structural integrity, and punctual delivery.
In high-throughput industries like mining, cement manufacturing, steel production, and electrical power generation, structural material failure due to extreme abrasion accounts for significant downtime and maintenance costs. The selection of wear-resistant cladding materials and flux-cored wire formulations directly impacts equipment availability. As a leading OEM Easy Flux Welder Manufacturer & Factory, Tangshan Runxing Machinery presents this technical whitepaper detailing the metallurgical mechanics, supply chain advantages, and application strategies that enable global enterprises to achieve longer equipment operational cycles.
Hardfacing overlays rely on the deposit of high-hardness alloys onto structural steel backings (typically ASTM A36 or Q235B). Our cladding process is engineered to synthesize a hypereutectic microstructure containing a high volume fraction of primary Cr7C3 chromium carbides. These carbides, with microhardness values reaching up to 1500 HV, are embedded securely within a tough, wear-resistant austenitic matrix.
The performance of bimetallic chromium carbide surfacing wear plates is determined by the carbide volume fraction (CVF) and orientation. By controlling heat input and cooling rates using our proprietary automated surfacing equipment, we orient the primary carbides perpendicular to the wear surface. This microstructural orientation yields superior wear resistance compared to conventional quench-and-temper alloy steels.
The transition from gas-shielded solid wires to advanced self-shielded flux-cored wires (FCAW-S) represents a major advancement in maintenance and repair welding. Our technical roadmap focuses on the following key areas:
Different industrial processes present unique wear challenges. A single-alloy solution is rarely sufficient. Our specialized engineering teams customize chromium carbide overlays for key heavy industries:
Our modern manufacturing facility in Tangshan, Hebei, integrates advanced automation and process controls. By manufacturing our own hardfacing wires and CNC multi-wire welding cladding machines, we control the entire production cycle. This vertical integration protects our clients from supply chain disruptions, stabilizes manufacturing costs, and ensures uniform quality across large product batches.
Through our exclusive export partnership with Hebei Yuwan International Trade Co., Ltd., we handle all international trade compliance, customs documentation, and logistics management. We maintain close engineering partnerships globally, including a 6-year history as a qualified agent for German brand VAUTID, ensuring our products meet high European and American quality standards.

Our standard CCO plates feature a high-carbon, high-chromium wear layer deposited on a mild steel backing. The overlay composition generally consists of 3.5% to 5.5% Carbon and 25% to 40% Chromium, producing primary M7C3 chromium carbides with a bulk hardness range of HRC 58 to 62+.
All international trade, customs clearance, shipping arrangements, and payment collection are handled by Hebei Yuwan International Trade Co., Ltd. This specialized trading structure ensures smooth export processes, while our Tangshan factory focuses entirely on production quality and meeting delivery timelines.
Self-shielded flux-cored wire (FCAW-S) contains core ingredients that generate their own shielding gas during welding. This allows for reliable outdoor repairs without wind disrupting gas coverage. It is an ideal solution for on-site maintenance of mining equipment and heavy processing plant machinery.
Yes. Runxing wear plates are designed for easy integration. The structural steel backing allows the plates to be welded directly to existing structures, while the chromium carbide overlay provides premium wear protection. The plates can be plasma cut, bent to specific radii, or counter-bored for bolt-on installation.
