Learn More >In modern industrial operations, abrasive wear, impact force, and structural degradation represent a multi-billion dollar drain on profitability. Heavy sectors—such as cement production, open-pit mining, iron and steel smelting, and port logistics—rely heavily on equipment designed to operate under severe structural stress. The deployment of premium alloys like Tungsten Carbide (WC) and Chromium Carbide (Cr7C3) represents the vanguard of wear prevention engineering.
As a leading Original Design Manufacturer (ODM), our focus is not merely supplying wear components but engineering molecular-level protection. Tungsten wire, heavy duty wear plates, and customized alloy cladding offer a shielding mechanism that protects infrastructure from destructive mechanical friction. Our specialized factories configure structural materials designed to withstand over 60 HRC, allowing mining operators and heavy industries to realize continuous operational uptime and dramatic cost savings.
"Information Gain in Metallurgy: Upgrading from conventional steel components to bimetallic chromium-carbide and tungsten alloy coatings can extend equipment service life by up to 300% to 500% under extreme wear conditions."
The engineering roadmap of hardfacing wire involves carefully controlling the chemistry of the weld pool. Normal carbon steels fail quickly when subjected to quartz sand, cement clinker, or heavy minerals. Hardfacing overlays deploy high levels of chromium, carbon, and refractory metals such as tungsten, niobium, and vanadium to generate hard primary carbides within a resilient matrix.
| Material Class | Key Elements | Microstructure Matrix | Typical Applications |
|---|---|---|---|
| Chromium Carbide (CCO) | Cr (25-35%), C (4-5.5%), Fe Balance | Cr7C3 Primary Carbides in Austenite Matrix | Chute Liners, Hopper Liners, Fan Blades |
| Tungsten Carbide Hardfacing | W (40-60%), C (3-5%), Fe/Ni Matrix | WC/W2C particles dispersed in ductile binder | TBM Cutters, Drill Bits, Severe Rock Slurry |
| Bimetallic Alloys | Complex Carbides (Nb, Mo, V, Cr) | Multiphase alloy composite structure | Cement Roller Repair, High-Temperature Chutes |
By using tungsten wire and specialized tungsten carbide flux cored wires, we achieve deposits that contain extremely hard particles within a ductile nickel or iron-based matrix. The tungsten carbide phase boasts a micro-hardness exceeding 2000 HV, offering effective resistance to scratch wear that would easily score standard martensitic or austenitic alloys.
Founded in 2010, Tangshan Runxing Machinery Co., Ltd. is a professional manufacturer based in Tangshan, Hebei Province—the core steel and heavy machinery manufacturing hub of China. We focus on the research, development, production, and on-site engineering of high-end hardfacing wear-resistant metal products and surface cladding technology.
Our core product lineup includes:
To ensure smooth global operations and compliance, our export processes are fully managed by Hebei Yuwan International Trade Co., Ltd. This strategic partnership allows our engineering teams to focus purely on metallurgy and manufacturing quality, while international trade specialists handle logistics, customs clearance, and global banking transactions seamlessly.
Clinker transport chutes, vertical grinding mills, and separator blades face intense, continuous sliding abrasion. Installing CCO liners extends component lifespans by up to 5x, preventing unexpected shutdowns and stabilizing output flow.
Earthmoving buckets, dumper truck beds, and primary crushers suffer severe rock impact combined with scratch wear. Our high-hardness overlay steel plates (RX-m series) absorb energy while maintaining structural profile integrity.
Sinter screening decks, coke guide plates, and blast furnace bell housings endure a combination of dry abrasive friction and temperatures up to 600°C. Runxing's high-temperature wear alloys remain stable under extreme heat cycles.
Pulverized coal injection pipes, fan impellers, and ash disposal systems are protected with inner-clad pipe fittings and thin, high-density chromium overlay wear sheets that minimize structural weight while maximizing erosion resistance.
Unloading grab buckets, ship loader chutes, and hopper systems processing hundreds of tons of ore per hour depend on our bimetallic composite plates to prevent metal fatigue and premature structural failure.
For applications where steel overlay plates face weight limitations or chemical corrosion, we integrate specialized wear-resistant high-purity alumina ceramics, offering excellent acid-base stability and dry wear properties.
Operating from Tangshan, Hebei, our factory leverages China's core steel production ecosystem. This proximity guarantees a reliable supply of premium structural steel backings and raw materials. By localizing raw powder synthesis, wire drawing, and robotic cladding processes under a single facility, we optimize the cost-to-quality ratio, delivering superior products far faster than regional competitors.
Furthermore, Hebei Yuwan International Trade handles logistics seamlessly. Whether shipping to Russia, Central Asia, Europe, or South America, our clients receive full customs clearance documentation, secure logistics routing, and transparent financial terms.
Runxing maintains strategic partnerships to ensure our R&D is at the forefront of wear science. For six consecutive years, we have served as a qualified agent for **VAUTID Germany**, incorporating their renowned high-quality welding materials into specialized wear plates.
Additionally, we actively collaborate with academic institutions like **Tangshan University**. The research team led by Dean Yuan Shaoqiang, Vice Dean Li Jing, and Professor Yang Yuehui (Metal Materials and Forming Technology Team Leader) conducts ongoing material studies at our plant, optimizing the microstructures of our flux-cored wires to improve wear performance in the most demanding operating environments.
We showcased our high-durability CCO wear plates and automatic welding machines to mining, construction, and power sectors across the African continent.
Runxing participated in Latin America's largest mining exhibition, introducing customized wear-resistant chute linings and rollers optimized for copper and lithium mining.
Our website launch streamlines the procurement of custom-dimension wear plates, flux-cored wires, and welding equipment for international operators.
Chromium Carbide Overlay (CCO) plates utilize chromium-carbide crystals (Cr7C3, approx. 1200-1600 HV) embedded in a tough iron-based matrix, which is ideal for sliding abrasion and moderate impact. Tungsten Carbide hardfacing utilizes WC/W2C particles (exceeding 2000 HV) in a nickel, cobalt, or iron matrix, providing maximum resistance to severe, high-stress abrasive grinding, such as that found in soil drilling, tunneling, and quartz-heavy operations.
Yes. As an OEM/ODM provider, we customize plate sizes, overlay thicknesses (e.g., 6+4, 8+6, 10+10, 12+12 mm), and base materials (Q235B, Q355, or stainless steel) to fit your equipment designs, CAD drawings, and chute configurations.
All export business is fully authorized and managed by Hebei Yuwan International Trade Co., Ltd. They handle customs clearance, export declarations, sea/land freight logistics, documentation, and payment processing, ensuring a reliable transaction process from our factory to your site.
Yes, our self-shielded and gas-shielded hardfacing wires are manufactured to standard diameters (typically 1.2mm, 1.6mm, 2.8mm, or 3.2mm) suitable for standard MIG/MAG or open-arc wire feed welding systems. We also offer specialized RX® automated cladding machinery for large-scale, multi-gun surfacing operations.
