Explore Details >Modern industrial environments demand components that resist progressive degradation under high-stress abrasive friction, thermal stress, and chemical erosion. Traditional structural steels fail rapidly under these parameters, leading to costly downtime and lost production capacity. The industry is experiencing a systemic migration toward Chromium Carbide Overlay (CCO) wear plates and specialized self-shielded flux-cored welding wires to prolong system lifespan.
By introducing high-chromium hypereutectic alloys onto a mild steel base plate via open-arc cladding, manufacturers form an overlay structure containing a high density of primary Cr7C3 hexagonal carbides. These carbides, oriented perpendicular to the wear surface, provide solid protection against hard geological particles (e.g., quartz, limestone, sinter, and clinker), while the ductile backing steel absorbs shocks and enables straightforward installation by conventional welding, cutting, and shaping processes.
Industrial buyers face significant challenges when sourcing hardfacing consumables and wear-resistant steels. Issues such as uneven carbide distribution, high parent metal dilution rates, excessive cracking (which must be controlled crack relief patterns and not structural failures), and chemical composition shifts can result in unpredictable part lifespans. As industrial installations prioritize sustainability and operating efficiency, procurement parameters have evolved from simply buying the lowest-cost materials to calculating the total lifecycle cost.
High-performance CCO plates must be produced under strict thermal conditions to limit heat input, minimize distortion, and control dilution. To guarantee metallurgical performance, suppliers must provide comprehensive testing protocols, including ASTM G65 dry sand/rubber wheel abrasion tests and Rockwell C hardness measurements.

This trading company completes all export work including customs clearance, shipment, documents and payment collection. Our factory focuses on product development and production to ensure stable product quality and on-time delivery.
Runxing Machinery sincerely hopes to establish long-term cooperation and achieve mutual benefit with you!
Heavy industries like mining, power generation, cement clinker processing, and steel manufacturing require tailored wear solutions rather than generic, one-size-fits-all components. In cement manufacturing, the grinding mill roller faces compressive stresses coupled with sliding abrasion. The optimal solution is an in-situ or shop-based rebuild using specialized hardfacing flux-cored wire to achieve a stress-relieved crack network that prevents structural separation.
For mining chutes that handle heavy rocks, wear-resistant liners must absorb high kinetic energy impact without fragmenting. Under these conditions, double-layer bimetallic CCO plates with an overlay containing niobium and carbon-rich carbides provide the necessary mechanical stability. Runxing Machinery works closely with metallurgical engineers to align hardness values, base plates, and carbide patterns with the physical demands of each application.
Industrial components require highly reliable, structured supply chains. To ensure seamless export logistics, all global shipments of Runxing Machinery are handled by the authorized export specialist Hebei Yuwan International Trade Co., Ltd. This entity manages customs clearance, documentation, international transport, and payment collection.
By separating manufacturing from export operations, Runxing Machinery’s engineering teams can focus entirely on metallurgical quality, precision machining, and timely production. This operational structure guarantees that customers in regions like Central Asia and Russia receive high-quality wear products that meet regional safety and custom standards.
The key issue for any cement plant lies in the availability of critical equipment. The key to equipment availability is wear resistance, and the performance of wear-resistant products determines the operating time of critical equipment.

Developing smart machinery is essential to maintaining competitive production rates and ensuring uniform metallurgical qualities. Runxing Machinery utilizes automated surfacing systems equipped with advanced numerical control processors. These systems regulate weld bead placement, cooling cycles, oscillation speeds, and welding current parameters to ensure high reliability.
By utilizing multi-gun welding heads that can operate in unison or independently, our systems reduce manufacturing cycle times while maintaining structural uniformity. This specialized equipment handles solid, gas-shielded, and open-arc self-shielded wires, allowing our workshop to manufacture complex wear-resistant configurations, from flat plates to intricate crushing rollers.
Future developments in wear-resistant surfacing center on alloy design and environmental efficiency. Runxing’s R&D is focused on creating ultra-fine carbide matrices and introducing multi-component boride phases to increase hardfacing layer toughness without reducing hardness.
Additionally, automated surfacing systems are being optimized to lower power consumption and reduce toxic emissions. These processes help reduce overall waste, lowering operating costs and supporting industrial sustainability goals.
Detailed technical explanations from our senior metallurgical team to assist procurement officers and engineering departments.
The cracks observed on the surface of CCO plates are stress-relief cracks. These form during the high-temperature overlay process as a result of differing thermal expansion rates between the chromium carbide layer and the carbon steel backing. These cracks are normal, distribute thermal stress, and do not compromise the plate's wear performance or cause delamination under normal operating conditions.
Gas-shielded wires require an external shielding gas (typically CO2 or Argon/CO2 blends) to protect the weld puddle from contamination. Self-shielded (open-arc) flux-cored wires contain gas-forming materials within their core, eliminating the need for gas tanks. This makes open-arc wires ideal for outdoor applications and onsite repairs under windy conditions.
Yes. The mild steel backing layer on bimetallic plates allows them to be welded directly onto steel structures. The plates can also be rolled or curved into cylinders and cones, with the wear-resistant overlay on either the inside or outside surface, depending on the application.
Runxing handles quality control at the factory level, conducting chemical checks, hardness tests, and thickness measurements. All export logistics, customs documentation, and international payments are managed by Hebei Yuwan International Trade Co., Ltd., ensuring compliance with regional shipping requirements.
Our wear plates conform to international standard DIN 8555. They undergo ASTM G65 testing to confirm their abrasion resistance, helping ensure they meet the durability requirements of heavy-duty industrial applications.
