Explore SpecsFounded in 2010 in Tangshan, Hebei Province—the heartland of China's heavy steel production—Tangshan Runxing Machinery Co., Ltd. is a premier professional developer and manufacturer specializing in the research, development, production, and on-site engineering of high-end hardfacing wear-resistant metal products.
Our core offerings include Chromium Carbide Overlay (CCO) wear plates, wear-resistant pipe systems, hardfacing flux-cored welding wires, automated overlay welding systems, and specialized industrial grinding roll rebuilding services. Relying on advanced metallurgical technologies and rigid quality controls, we supply heavy industrial sectors with solutions that dramatically improve operational lifetimes and reduce costly downtime.
To guarantee international transaction efficiency and compliance, all export operations are authorized and handled through our specialized global trading division, Hebei Yuwan International Trade Co., Ltd. This strategic division coordinates customs clearances, shipping documentation, and global payments, letting our production facilities focus entirely on craftsmanship, technical R&D, and on-time delivery.
As global industrial plants optimize for resource conservation and reduced carbon footprints, extending component service life through precise cladding has evolved from maintenance to a key economic strategy.
Modern mining extraction, coal power generation, cement fabrication, and steel mills expose structural metal parts to extreme combinations of mechanical stress, temperature, and sliding abrasion. Standard structural carbon steels lack the microstructure to survive these abrasive forces, failing within short operational periods.
The solution lies in depositing high-performance alloy overlays. Chromium Carbide Overlay (CCO) technology constructs a composite layer rich in hexagonal M7C3 primary carbides embedded in a tough, ductile matrix. Runxing Machinery optimizes this overlay structure, achieving a balance of high hardness (often 58–62 HRC) and structural integrity to prevent premature spalling and crack propagation under stress.
Automating this welding process is critical to ensuring consistent carbide distribution and minimizing base metal dilution. Manual weld deposition typically leads to irregular chemistry, high dilution (mixing base metal with overlay alloys), and internal thermal stress.
Our machines utilize four welding guns working in synchronization or independently. This multi-axis coordination quadruples deposition rates while balancing thermal gradients across large plates.
Incorporates a high-resolution 10.2-inch industrial touch-screen CNC panel. Allows precise path programming, oscillation swing configurations, and live current control.
Specially tuned parameter ranges for open-arc, self-shielded, and submerged-arc deposition. Enables low base-metal dilution rates (typically under 10%) to preserve alloy chemistry.

Our plates feature a hypereutectic microstructure containing primary chromium carbides (M7C3, where M = Cr, Fe, and other minor alloying elements). The volume fraction of these primary hexagonal-shaped carbides is maintained between 35% to 45%, embedded in a tough austenite matrix. This specific microstructure offers high wear protection against abrasive particulates.
Hebei Yuwan International Trade Co., Ltd. is our fully authorized global trading arm. Utilizing a dedicated trading division allows our manufacturing plant to focus on R&D, quality control, and production scheduling. Meanwhile, Yuwan handles international customs clearance, logistics, and multi-currency transactions, ensuring smooth and compliant deliveries worldwide.
Automatic cladding systems deliver precise control over parameters like travel speed, oscillation amplitude, and current. This consistency keeps the dilution rate (mixing base metal with overlay alloys) below 10%, maximizing hardness in the primary layer. It also ensures uniform carbide distribution, reduces internal stresses, and accelerates manufacturing throughput.
Our relationship as an authorized VAUTID agent since 2019 allows us to incorporate high-end German metallurgical raw materials and formulations into our custom products. Combining VAUTID's alloy designs with our cost-efficient manufacturing in Tangshan enables us to offer premium wear solutions at competitive rates.
The dilution rate refers to the percentage of base metal that melts and mixes with the deposited alloy overlay. High dilution rates dilute the concentration of critical alloying elements like chromium and carbon, lowering the density of primary wear-resistant carbides. Our automated machinery and optimized weld paths minimize dilution, ensuring the wear layer maintains its target hardness and wear properties.
Standard CCO plates operate effectively up to approximately 350°C. For extreme temperature applications (e.g., sintering systems in steel plants, hot air ducts in power stations), we design specialized high-temperature alloys enriched with elements like Niobium (Nb), Boron (B), and Tungsten (W). These plates resist temper softening, preserving their wear-resistant properties up to 800°C.
