See detailsIn modern bulk-handling and materials processing sectors, mechanical downtime caused by abrasive, erosive, and impact-driven surface wear constitutes one of the most significant operating cost vulnerabilities. Mitigating these wear mechanisms requires more than simple surface coatings. It demands highly engineered metallurgical solutions designed to handle specific field forces. As an industry-leading global manufacturer, we deliver bimetallic cladding materials and alloy-dense welding wires that maintain critical system integrity under the most punishing working conditions.
Underlying Wear Principles: Chromium Carbide Overlays (CCO) work because of their unique microstructural chemistry. The primary M7C3 carbides, which crystallize during our controlled solidification process, achieve macro-hardness ranges between 1500 and 2000 HV. This creates an extremely resilient barrier against high-stress grinding abrasion.
Producing robust wear plates like our RX®wp 7600 requires careful control of the boundary layer between the carbon steel base and the wear-resistant overlay. Subcritical carbon dilution must be minimized to ensure the overlay maintains its high alloy integrity. If excess iron from the base carbon plate migrates into the deposit, it dilutes the chromium and carbon levels, preventing the formation of necessary primary chromium carbides. Our automated manufacturing lines use specialized low-heat surfacing techniques that prevent this dilution, ensuring our CCO wear plates deliver consistent protection from the surface all the way down to the base metal interface.
In field environments, shielding gases are easily disrupted by wind, leading to weld porosity and reduced structural integrity. Self-shielded flux-cored wires solve this problem. These wires are packed with gas-generating elements and deoxidizers like aluminum, magnesium, and titanium. During welding, these materials form a reliable protective envelope around the arc and pool, sealing out atmospheric oxygen and nitrogen. This ensures high-integrity deposits even in harsh outdoor conditions, making them ideal for rebuilding worn equipment on-site.
Manufacturing Supercenter
Tangshan Runxing Machinery Co., Ltd. was established in 2010 in Tangshan, Hebei Province—a key hub of China's heavy industry and steel metallurgy. This strategic location gives us secure access to high-grade steel substrates and alloy raw materials, allowing us to maintain a highly stable and cost-efficient supply chain.
We are a dedicated manufacturer focusing on the research, development, production, and field installation of hardfaced metal components. Our specialized facility houses advanced automated cladding machines, wire drawing lines, and custom machining equipment. This setup allows us to supply both standard chromium carbide plates and custom wear components built to precise engineering drawings.
To ensure smooth global logistics, all international trade operations are managed by our authorized partner, Hebei Yuwan International Trade Co., Ltd. This partnership covers customs clearance, ocean shipping, banking documentation, and payment processing, allowing our engineering team to focus entirely on quality control and manufacturing precision.
Global Sector Integrations
Raw mill vertical grinding rollers, separator guides, chute liners, and raw material feed hoppers face intense pressure. Our CCO materials help extend service life and minimize maintenance downtime.
Chutes, excavator buckets, conveyor transfer points, and heavy crushers face constant abrasion. We engineer custom high-hardness plates and wire materials to withstand these extreme forces.
Operating in environments with high thermal loads, sinter handling, and continuous abrasion requires specialized protection. Our bimetallic plates resist micro-fractures and thermal fatigue.
Protecting coal pulverizer housings, ash handling piping, exhauster fan blades, and hopper chutes from erosion. High-density chromium alloys prevent premature pipe blowouts and turbine wear.
Stacker-reclaimer buckets, transfer chutes, and ship loading hoppers experience high throughput wear. Custom-fabricated CCO plates ensure smooth material flow and prevent surface damage.
For high-velocity sliding wear and wet slurry applications, high-purity alumina ceramics provide an excellent alternative where metallurgical solutions reach their wear limits.
The industrial hardfacing industry is shifting toward automated, high-precision, and digital production. Traditional manual stick welding is increasingly replaced by multi-axis CNC systems and robotic cladding setups. This modern approach delivers precise control over parameters like heat input, travel speed, and overlap ratios, resulting in highly consistent microstructural quality.
Additionally, developments in chemical composition—such as introducing trace elements like boron, niobium, and vanadium into the alloy matrix—are creating next-generation materials. These additions refine the primary M7C3 grains, producing a denser wear-resistant layer that handles impact and thermal cycles far better than standard chromium alloys.
For global procurement managers, evaluating wear-resistant materials goes beyond looking at the initial purchase price. The focus should be on the total lifecycle cost of the equipment. Low-cost, non-standard wear plates often fail early due to dilution issues or brittle cracking, leading to unscheduled repairs and costly downtime.
By using quality plates that meet DIN 8555 specifications and sourcing from qualified suppliers, companies can significantly extend service intervals. This reliable performance prevents unplanned outages, protecting both upstream and downstream production processes and lowering the overall cost of ownership.

Our chromium carbide overlay wear plates feature a hypereutectic microstructure containing over 30% primary M7C3 chromium carbides. These carbides are embedded in a tough, austenitic matrix, resulting in a macro-hardness of 58 to 62 HRC. This configuration provides excellent wear protection under abrasive conditions while maintaining structural toughness.
Yes. The base plate is made of weldable carbon steel (typically Q235B or Q355B), allowing it to be welded directly to structural elements. The plate can also be formed or rolled, with the overlay facing inward or outward, depending on the requirements of your application.
During the cooling phase of production, fine transverse cracks form naturally due to thermal tension. These stress-relief cracks are a normal feature of high-hardness overlays and help prevent distortion or buckling. They are confined to the overlay layer and do not extend into the tough carbon steel substrate.
