Learn More >Industrial processing machinery operates under aggressive environments where mechanical wear, erosion, and high-temperature oxidation continuously degrade component surfaces. To mitigate this degradation, advanced overlay technologies such as flame spray (Flamspray), arc spraying, and weld overlay cladding are applied to establish resilient boundary protections.
By depositing a high-alloy metallurgy onto low-carbon or low-alloy structural steels, manufacturers achieve a composite component with a tough, ductile substrate capable of handling structural loads, and an exceptionally hard superficial layer optimized for surface wear. This bimetallic concept offers major economic advantages, as the bulk structure remains cost-effective, while the high-alloy defense is concentrated exactly where wear occurs.
Our Chromium Carbide Overlay (CCO) plates utilize this concept by overlaying primary hypereutectic M7C3 chromium carbides (with hardness levels typically exceeding 1500 HV) onto structural backing steel. The microscopic distribution of these carbides within a resilient, austenitic matrix creates a barrier that interrupts the abrasive micro-ploughing and micro-cutting mechanisms caused by hard mineral particles.
Hexagonal primary carbides provide high micro-hardness, defending against sharp abrasive particles.
Tough background matrix absorbs structural shocks, preventing carbide spalling and delamination.
Precise control of overlay welding parameters limits dilution from the backing steel, preserving chemistry.
Controlled cooling and micro-fissuring release residual welding stresses without compromising wear resistance.
Founded in 2010 in Tangshan, Hebei Province—the heartland of China's heavy industry and steel metallurgy—Tangshan Runxing Machinery Co., Ltd. has established itself as a leading professional developer, manufacturer, and on-site engineering constructor of hardfacing metal wear products.
We specialized early in the field of metal surface hardfacing technology, integrating chemical research, manufacturing, and design processes to deliver robust wear-resistant parts. Our modern facilities produce high-quality Chromium Carbide Overlay (CCO) plates, custom wear liners, wear pipes, hardfacing flux-cored welding wires, and automated surfacing machinery.
Our core operating philosophy rests on four key pillars: Integrity, Superior Quality, Innovation, and Sustainable Development. We strive to reduce plant downtime, enhance operating cycles, and deliver predictable maintenance schedules to global heavy industries.
Combining heavy metallurgical experience with state-of-the-art robotics to produce consistent, high-performance wear protection systems at scale.
Our specialized RX® Surfacing equipment integrates advanced CNC units via 10.2-inch interactive touch control interfaces. The uniform speed swing welding controls target precise weld bead oscillation, minimizing thermal stress in the base plate. The multi-gun configuration allows independent or simultaneous operation to speed up production rates and reduce manufacturing lead times.
By fine-tuning critical parameters like electrical current, voltage, travel speed, and powder feed rates, we control the dilution rate of the hardfacing layer with the substrate steel. This ensures that the primary chromium carbide structure remains consistent from the interface boundaries all the way to the top of the wear layer, maintaining uniform wear rates throughout its service life.
To guarantee smooth transactional logistics for our global partners, all international exports are authorized to Hebei Yuwan International Trade Co., Ltd. By separating export trade operations from physical production, we allow the factory team to focus entirely on quality and output, while the logistics team manages customs clearance, documentation, and secure global payments.
Runxing designs custom-engineered wear products tailored to target the specific damage mechanisms found across heavy industries.

We are moving beyond simple chromium-iron binaries. By introducing key micro-alloying elements—such as Niobium (Nb), Titanium (Ti), Tungsten (W), and Boron (B)—our next-generation hardfacing alloys precipitate complex multi-component carbides. This creates a refined grain structure that exhibits superior resistance to high-stress gouging and fine abrasive wear.
To complement traditional open-arc and submerged-arc welding, our R&D roadmap focuses on commercializing high-power diode laser cladding. The highly concentrated thermal input of industrial lasers minimizes the heat-affected zone (HAZ) and keeps base dilution below 5%, allowing thinner, high-purity overlays to be deposited on critical surfaces.
We prioritize sustainability by offering advanced reclaim rebuild services. Rebuilding worn assets—such as crushing rollers and kiln gear rings—back to their original dimensions saves over 70% in raw materials and carbon emissions compared to manufacturing brand-new replacements, supporting a circular industrial economy.
Global procurement teams require materials that conform strictly to international metallurgical standards. Our manufacturing processes align with recognized standards like DIN 8555, ASTM G65, and ISO 9001, ensuring that our products meet expected field performance metrics.
Since 2019, Tangshan Runxing Machinery Co., Ltd. has served as an authorized partner for VAUIID (VAUTID) in Germany, a recognized pioneer in metal wear protection. This long-standing relationship has enabled us to import specialized raw materials, refine our alloy formulations, and apply European-caliber quality controls to our entire high-speed production line.
Additionally, our global logistics are fully managed by Hebei Yuwan International Trade Co., Ltd. This partnership streamlines customs clearance, handles all export documentation, and simplifies transaction processing, allowing our technical teams to focus fully on product engineering.
A reference checklist for procurement directors and plant engineers auditing potential wear-resistant product manufacturers.
To ensure wear protection systems deliver a strong return on investment, auditing engineers should request and verify the following technical parameters during pre-qualification:
Ask for optical emission spectrometry reports to verify chromium levels (min 28-30% for standard CCO) and carbon levels (3.5-5.5%). Request microstructural images showing carbide volume fraction (minimum 35-45% primary M7C3 carbides).
Request cross-sectional micro-hardness surveys. High dilution from the backing steel reduces the carbon/chromium content in the first pass, leading to a softer interface region that can wear away quickly.
Ensure the backing plate uses a fully weldable, structural steel grade (like Q235B, Q355B, or ASTM A36) to prevent underbead cracking during installation and welding in the field.
Confirm that the plate exhibits uniform, closely spaced stress relief micro-cracks perpendicular to the weld bead direction. These cracks release thermal contraction stresses and prevent warping.
