Explore Specifications >Abrasive wear remains one of the costliest degradation mechanisms in heavy industries. Globally, the energy consumed to replace worn parts, along with productivity lost during shutdowns, costs industrial operators billions annually. Minimizing these losses requires materials engineered to withstand extreme mechanical stress, heat, and sliding abrasion.
Runxing Machinery specializes in ODM Machine Welding and hardfacing wear protection. By utilizing advanced chromium carbide overlays (CCO) and specialized flux-cored wires, we provide custom industrial components designed to extend service life by up to 300% compared to standard carbon steels.
This report outlines the technical principles of hardfacing cladding, local application scenarios, automated equipment design, and China's supply chain advantages that make Runxing a preferred global partner.
Founded in 2010 in Tangshan, Hebei Province—the heart of China's metallurgy and heavy manufacturing industry—Tangshan Runxing Machinery Co., Ltd. is a professional manufacturer focused on the R&D, production, and on-site construction of hardfacing wear-resistant metal products.
Our core manufacturing capabilities cover chromium carbide overlay (CCO) wear plates, custom-processed wear liners, bimetallic pipes, hardfacing flux-cored welding wires, and automated surfacing machinery. We are a trusted provider of customized industrial wear-prevention solutions for cement, steel, mining, dredging, and power generation companies globally.
Read Corporate Profile >Runxing Machinery maintains an academic and technical collaboration with Tangshan University. Key engineering members, including Dean Yuan Shaoqiang, Vice Dean Li Jing, and Professor Yang Yuehui (Metal Materials and Forming Technology team leader), inspect and support our metallurgical testing. This integration guarantees state-of-the-art wear testing and carbide orientation monitoring.
For more than six consecutive years since 2019, Runxing has been a qualified agent for VAUTID Germany, utilizing high-quality VAUTID welding materials to manufacture specialized wear plates for severe service environments.
Export Operations: To ensure compliance and streamlined international transactions, all export logistics, customs clearance, and payments are managed through our authorized trade partner, Hebei Yuwan International Trade Co., Ltd.
Explore our primary engineering systems designed to defend mechanical equipment against high-stress grinding abrasion, erosion, and impact.
Our composite wear plates consist of a structural base steel (Q235/A36) and a hardfaced cladding layer deposited using open-arc welding. Corresponding to DIN 8555 standards, the cladding layer features dense primary chromium carbides (M7C3) oriented perpendicular to the wear surface, yielding a surface hardness of 58 to 62 HRC.
Technical Datasheets >
Engineered for high-stress grinding abrasion with low impact, our self-shielded open-arc flux-cored wires deposit a rich chromium-carbide alloy. The wire chemistry is balanced with deoxidizers to eliminate the need for external shielding gas during field repairs or factory production, guaranteeing low-porosity, crack-controlled deposits.
Wire Chemistry Catalog >
Plasma Transferred Arc (PTA) cladding delivers precise overlay coatings with minimal dilution of the base material. This process is ideal for thin-layer surfacing applications where dimensional accuracy and minimal distortion are critical, such as high-temperature fan blades and complex valve assemblies.
Process Parameters >
Designed for large-scale fabrication, our automated hardfacing welding machines feature four-gun multi-arc setups working independently or in unison. Controlled via a 10.2-inch industrial PLC touchscreen, the system supports oscillated, uniform swing-arc welding with adjustable path spacing, accommodating solid, flux-cored, and open-arc wires.
Machinery Specifications >
Runxing handles the complete fabrication cycle, including structural plasma cutting, roll forming, bimetallic pipe welding, and custom-liner assembly. We build industrial components directly to OEM/ODM specifications, providing plug-and-play installation for chutes, hopper liners, and cyclone separators.
Engineering Portfolio >
Heavy machinery rollers (vertical cement mills, coal pulverizers, continuous steel casting rolls) operate under high compressive load. Our specialized roller repair service utilizes custom alloy rebuilds and hardfacing layer claddings to restore worn roll profiles on-site or in-shop, significantly reducing replacement capital costs.
Roll Repair Case Studies >How Runxing's hardfacing technology mitigates material wear, operational downtime, and capital expenditures across global sectors.
Cement plants require long system availability under high dust, thermal, and mechanical stress. Our CCO wear plates are utilized for raw material hopper liners, chute surfaces, cyclone separators, and vertical mill casing liners, protecting systems from abrasive clinker and raw stone impact.
See Cement Cases >
Mine operators demand equipment reliability under severe impact and sliding abrasion. We provide wear-resistant liner kits, loader bucket shroud protections, dump-truck bed liners, and high-hardness chute liners designed to withstand copper, iron ore, and oil sands processing.
See Mining Cases >
Operating conditions in blast furnaces and sinter plants involve high temperatures and aggressive mineral abrasion. We supply heat-resistant bimetallic plates and automated hardfacing wires for coke screen plates, sinter breaker beams, and blast furnace receiving hoppers.
See Steel Cases >
Pulverized coal transport causes severe erosion on fan blades, transport elbows, and burner nozzles. Runxing manufactures custom thin-overlay clad plates and bimetallic piping systems that maintain thermal stability while resisting high-velocity particulate erosion.
See Power Cases >
Bulk cargo loading systems process tons of coal, gravel, and grain daily, inducing high-frequency surface friction. We manufacture drop chutes, hopper linings, and grab-bucket edges using high-strength structural base plates cladded with carbide overlays.
See Port Cases >
For applications where metallic alloys face chemical corrosion or high-frequency impact at vertical angles, our wear-resistant alumina ceramic panels—sintered from high-purity ultrafine alumina powder—provide an alternative wear-protection solution.
See Alumina Cases >Tangshan, located in Hebei Province, is China's largest steel manufacturing hub. This location provides Runxing Machinery with direct access to high-grade base structural steels, alloy elements, and metallurgical research. This proximity reduces material transport costs and enables us to source raw inputs efficiently.
Additionally, our export trading partner, Hebei Yuwan International Trade Co., Ltd., manages global shipping operations. They handle export documentation, customs clearance, sea-freight logistics, and international payment transactions, allowing our manufacturing team to focus entirely on quality control and technical development.

How we are evolving our hardfacing alloys and automated machinery to meet the next generation of industrial requirements.
Runxing is testing chromium-carbide alloys modified with titanium (Ti) and niobium (Nb). These elements refine the carbide microstructure, creating smaller, more evenly distributed carbide precipitates. This structure improves impact resistance while maintaining high hardness (up to 65 HRC).
We are integrating real-time optical tracking cameras into our automated welding machines. These sensors monitor the weld pool, adjusting travel speed, oscillation width, and current in real time to compensate for base plate distortion and heat buildup.
Our R&D team is developing self-shielded flux-cored wires that produce fewer airborne particulates and low hexavalent chromium emissions. This development aims to align field-repair activities with stricter workplace safety and environmental regulations.
