Explore ProductHard surface welding wire (often referred to as hardfacing wire) serves as the primary defense mechanism against structural deterioration in severe industrial environments. The fundamental principle governing hardfacing is the deposition of an alloy layer containing hard microstructural constituents—most notably primary chromium carbides ($M_7C_3$) and secondary complex borides/carbides—embedded in a tough matrix. Depending on the exact environmental forces (low-stress scratching abrasion, high-stress grinding abrasion, impact, erosion, or corrosion), metallurgical composition must be adjusted.
For severe sliding abrasion, Chromium Carbide Overlay (CCO) wire is the industry standard. These wires typically feature a high chromium (25-35%) and carbon (4-6%) content. During the solidifying process, primary chromium carbides precipitate out first, forming hexagonal crystals with hardness levels reaching up to 1500 HV. This matrix prevents abrasive quartz or mineral particles from cutting through the structural backing steel.
A common misconception in the hardfacing supply chain is that Rockwell C hardness (HRC) is the sole predictor of wear life. In fact, two alloys with the same HRC rating can perform vastly differently under the same working parameters. The key factor is the microstructural phase ratio. A matrix consisting of martensite with high carbide density offers exceptional wear resistance but low impact resistance. Conversely, an austenitic matrix work-hardens under impact, absorbing kinetic energy without catastrophic spalling or cracking.
Runxing Machinery specializes in the production of high-performance flux-cored wires (such as RX®wp 7600 chemistries) that balance the ratio of hard phases to tough phases, ensuring optimal performance. By modifying the wire flux with niobium (Nb), vanadium (V), or tungsten (W), we produce sub-micron complex carbides that provide extreme resistance to high-temperature degradation and fine-particle erosion.
Founded in 2010 and located in Tangshan, Hebei Province—the heartland of China's metallurgy and heavy machinery manufacturing—Tangshan Runxing Machinery Co., Ltd. has established itself as a premier research-oriented manufacturer of wear-resistant surface materials. Over the past decade, our production floor has expanded to cover advanced production lines for Chromium Carbide Overlay (CCO) wear plates, customized wear liners, wear-resistant pipe systems, automatic hardfacing machines, and a comprehensive line of flux-cored welding wires.
Driven by the business philosophy of "Integrity, Superior Quality, Innovation & Sustainable Development," we operate under strict quality management systems to guarantee reliability. To support our global clients, all export administration is managed via Hebei Yuwan International Trade Co., Ltd., ensuring seamless customs processing, logistics coordination, and cross-border financial clearances.
Our specialized hardfacing wires and composite plates are implemented in diverse, punishing operating environments worldwide. We engineer customized overlays for high impact, high temperature, and fine-particle erosion.
We mitigate severe grinding abrasion on vertical roller mill (VRM) tires, separator vanes, and raw material transport chutes.
