See more products >In heavy industrial contexts, structural steel failure resulting from abrasive wear, erosion, and high-impact degradation accounts for massive operational downtime and millions of dollars in losses annually. Standard carbon steel lacks the microstructural resilience to endure long-term wear fields. This is where Chromium Carbide Overlay (CCO) and specialized welding wires play a critical role. By forming a dense eutectic matrix populated with primary chromium carbides ($M_7C_3$), the composite surface provides a hardness ranging from 58 to 65 HRC.
As leading ODM/OEM metal wire manufacturers, Tangshan Runxing Machinery Co., Ltd. customizes the chemical deposition of hardfacing flux-cored wires to control dilution rates during deposition. The chemistry typically incorporates 4.0% to 5.5% Carbon and 28% to 35% Chromium, which triggers the crystallization of primary chromium carbides during solidification. These carbides are held in an incredibly tough austenitic matrix, ensuring that even when exposed to high-stress grinding abrasion, the material resists micro-spalling and delamination.
Compliance & Quality Standards: Our manufacturing processes correspond strictly to DIN 8555 parameters, guaranteeing that the weld metal deposit maintains the precise balance of high carbide volume fraction (CVF) required to withstand sliding abrasion under heavy loads.
Through our dedicated R&D, we focus on the production of self-shielded flux-cored wires that eliminate the need for external shielding gas. This structural convenience makes our products highly suited for on-site hardfacing repair of large-scale equipment, including vertical mill rollers, conveyor chutes, and hopper liners. The self-shielding elements within the flux core react at the arc temperature to create a protective slag and gas shield, securing clean, porosity-free weld deposits even under windy, variable field conditions.
Founded in 2010, Tangshan Runxing Machinery Co., Ltd. is a premier professional manufacturer located in Tangshan, Hebei Province. We focus on the R&D, production, and on-site construction service of hardfacing wear-resistant metal products. Our mature, advanced metal surface hardfacing technology ensures stable, long-lasting quality across international supply lines.
To provide streamlined international delivery and contract compliance, all export operations are fully authorized and managed by Hebei Yuwan International Trade Co., Ltd. This specialized trading partner coordinates customs clearance, maritime shipment, bank documentation, and payment collection. This structure allows our factory engineers to focus entirely on quality control.
For high-demand, high-performance wear protection, Runxing has proudly operated as an authorized agent for VAUTID (Germany) for six consecutive years starting from 2019. By utilizing VAUTID's top-tier raw materials alongside our custom solutions, we guarantee that our structural overlays meet the most stringent Western European engineering criteria.
Across the global landscape of mining, heavy metallurgy, port operations, and thermoelectric energy generation, mechanical wear acts as a continuous drain on productivity. Equipment like vertical grinding mills, heavy conveyor transfer points, and dry-bulk unloading docks face severe abrasive dynamics. By applying custom-tailored hardfacing alloys, operators can extend component lifespans by 300% to 500%. This not only reduces the carbon footprint related to component replacement but also minimizes total lifecycle costs.
Runxing's strategic engineering solutions are actively deployed throughout the mining hubs of Central Asia and the industrial facilities of the Russian Federation. Because global supply chains require absolute compliance with international financial and transport laws, the integration of Hebei Yuwan International Trade Co., Ltd. as our exclusive foreign trade facilitator ensures seamless transactions. Customers receive guaranteed delivery terms, fully certified materials, and streamlined customs clearance processes, allowing procurement managers to minimize procurement risk.
Furthermore, our close partnership with academic and research institutions keeps us at the forefront of surface engineering research. In 2023, leaders of Tangshan University—including Dean Yuan Shaoqiang, Vice Dean Li Jing, and Professor Yang Yuehui (Team Leader of Metal Materials and Forming Technology)—visited our manufacturing plant. This academic-industrial collaboration ensures that our technological advancement and alloy formulations remain continuously aligned with the latest scientific discoveries in metal forming and grain structure optimization.

See more cases >Operational efficiency is not solely dependent on premium alloy wires; the precision and uniformity of deposition are equally critical. Our proprietary RX® Surfacing Equipment features an advanced numerical control system, managed through a 10.2-inch touchscreen PLC panel. The welding mechanism is configured with four independent welding guns, capable of operating simultaneously or independently. This allows for a fast deposit rate without overheating the substrate, keeping distortion to a minimum.
The system provides automated control of the uniform speed swing welding process, where both narrow and wide welding paths can be customized to match the geometry of the target plate or roller. This system accommodates solid-core, flux-cored, and self-shielded wires in open-arc, metal-powder, or submerged-arc configurations. These adaptations are key when rebuilding worn surfaces back to original specifications, as seen in roll repairs, coal pulverizer disks, and steel mill guide plates.
Industrial Roller Services: Heavy-duty rollers used in cement milling and mineral crushing are divided into conveyor/casting rolls and grinding rolls. Runxing provides professional restoration services using precise hardfacing overlays. This process repairs the component to original tolerances and adds a wear-resistant surface that lowers future maintenance and operating costs.
Our engineering services extend to complete machining processes, structural fabrication, and custom liner design. We work with clients to analyze their wear patterns, develop an alloy formula, configure the base steel plate, and finish-machine the final assembly. This end-to-end control ensures that our hardfaced liners slide, bolt, or weld into place without field adjustments.

Read Article >The demand for harder and tougher surfaces is driving wear-resistant materials away from traditional iron-carbon alloys. Next-generation materials focus on complex carbide alloys (containing Nb, Ti, V, and W) and boride-modified matrices. Our R&D center is developing nano-structured hardfacing wires that refine the chromium carbide grain size. Finer grain sizes reduce the risk of cracking under thermal and physical stress, improving performance in impact-heavy environments.
We are also upgrading our automation capabilities. By integrating optical tracking sensors with our multi-gun welding systems, our machines can monitor the molten weld pool in real-time. This helps adjust parameters automatically to prevent defects, providing a more consistent and reliable coating. This technology is critical for complex geometries like screw flights, exhaust fans, and complex dredging pipes.
Additionally, we are exploring hybrid liners that combine steel plates with sintered alumina ceramics. This design utilizes the high hardness of ceramics alongside the impact absorption of steel, providing a durable solution for high-abrasion applications in cement and steel processing.
