Request Alloy MetallurgyIn modern global manufacturing ecosystems, wear and tear accounts for billions of dollars in lost operating efficiency, mechanical failures, and forced shutdown intervals. Hardfacing technology—using specialized alloy-cored wire to deposit highly resistant metallurgical coatings on structural parts—has transitioned from a maintenance procedure to a key design requirement.
Industrial operations in raw mining, steel production, thermal power generation, and marine port cargo handling require hardfacing alloys that can withstand extreme environments. Runxing Machinery bridges this gap by manufacturing premium self-shielded flux-cored wires and bimetallic wear plates.
"Through structural optimization and academic research alongside Tangshan University, we customize wear compounds to maximize operating lifespan under abrasive stress."
Typical joining wires struggle with complex abrasion environments. Our specialized high-chromium hardfacing flux-cored wires focus on creating dense microstructures where primary M7C3 eutectic carbides are oriented perpendicular to the wear surface. This configuration ensures:
How Tangshan Runxing engineers microalloyed solutions for severe mechanical tribological systems.
By introducing trace quantities of niobium (Nb), boron (B), and vanadium (V) into the wire core, we refine grain boundary networks. This ensures structural strength and prevents stress crack propagation under variable loads.
Our advanced flux powder filling and drawing line maintains consistent fill ratios. This guarantees uniform deposition rates and chemical profiles across every roll of wire.
By removing the need for external shielding gas, our self-shielded open arc welding wires allow field teams to repair parts on-site, even in windy conditions.
Founded in 2010 in Tangshan, Hebei Province—a premier heavy industrial hub in China—Tangshan Runxing Machinery Co., Ltd. has grown into an international leader in the R&D, manufacturing, and on-site engineering of wear-resistant surface cladding.
Our manufacturing center covers all aspects of surface wear protection, specializing in Chromium Carbide Overlay (CCO) wear plates, wear-resistant pipes, flux-cored welding consumables, and automated rebuilding machinery.
We operate in partnership with Hebei Yuwan International Trade Co., Ltd., which handles export customs clearance, maritime shipping, and documentation. This allows our factory teams to focus on manufacturing consistency and technical development.
Additionally, we serve as an authorized agent for the German brand VAUTID, which highlights our commitment to international quality standards.
Our customized solutions protect industrial machinery from wear under complex operational stresses.
Protects critical equipment from raw meal abrasive wear. Our CCO overlay plates extend the service life of feed chutes, separator vanes, and cyclones, helping cement plants run continuously.
Increases productivity and reduces operating costs in iron, copper, and coal mining. Built for extreme impact abrasion on hopper liners, dump truck beds, and bucket wheel excavators.
Protects parts from high temperatures and abrasive iron ore sinter. Used on blast furnace bell tops, coke screens, guide plates, and transfer chutes to keep lines running.
Reduces wear in thermal coal-pulverizer systems. Our hardfacing wire extends the service life of coal pipes, mill liners, classifier cones, and exhaust fan blades.
Protects handling equipment and dredge lines from wet sand abrasion. Used on suction hopper dredgers, sand discharge pipes, and bulk grab buckets to prevent slurry erosion.
Uses high-purity alumina ceramics sintered at high temperatures to provide erosion protection for high-velocity particle conveying lines.
Ongoing development of custom cladding formulations designed to operate at temperatures exceeding 800°C in waste-to-energy recovery plants.
Developing specialized wear protection for shield tunneling cutter heads and tunnel boring machine components used in urban utility installations.
Our RX® Surfacing Equipment features an advanced numerical control system with a 10.2-inch industrial touch screen. The unit supports adjustable wide or narrow welding paths, maintaining uniform swing speeds to guarantee smooth weld runs and consistent penetration depths.
The welding mechanism utilizes four independent guns, which can operate simultaneously or independently. This design allows operators to quickly adjust weld profiles to match specific material requirements.
The system works with solid, flux-cored, and self-shielded wires under open-arc, metal-cored, or submerged-arc configurations. It is designed to manufacture composite wear plates, rebuild grinding rolls, and repair vertical mill components.
Industrial grinding rolls operate under continuous load. In steel, cement, and power generation mills, roller wear directly affects overall grinding output and increases fuel consumption.
Runxing Machinery provides customized roll rebuilding services, utilizing specialized high-alloy flux-cored wires to restore worn rollers. Rebuilding worn assemblies reduces replacement costs and extends part life, helping plants maintain operational efficiency.

Expert technical responses to common questions about hardfacing, welding wire composition, and mechanical maintenance.
Self-shielded flux-cored wire contains gas-forming agents within its core ingredients. This eliminates the need for high-pressure gas cylinders and shielding accessories, allowing repair crews to operate directly outdoors in windy environments. It also simplifies logistical requirements for remote industrial sites.
DIN 8555 defines classifications for welding consumables based on chemical composition, wear mechanism resistance, and alloy structures. Our composite plates and welding wires are categorized under DIN 8555 to help engineers select the correct hardness and wear performance for specific applications.
The hexagonal crystal structure of M7C3 primary carbides exhibits a microhardness exceeding 1500 HV. In our overlay plates, these carbides are oriented perpendicular to the wear surface, forming a barrier that prevents abrasive particles from cutting into the base metal.
Tangshan Runxing focuses on production, metallurgical R&D, and quality control. All export logistics, customs declarations, shipping arrangements, and financial transactions are handled by Hebei Yuwan International Trade Co., Ltd., ensuring compliance with global import and export requirements.
Depending on the composition and layer thickness, our overlays typically range from 58 to 65 HRC (equivalent to 650–850 HV). This provides a balance of abrasion resistance and resistance to spalling under moderate impact.
