See detailsIn modern industrial operations, the durability of steel and composite materials dictates overall operational efficiency, equipment availability, and cost control. While Hardox Steel (ranging from Hardox 400, Hardox 500, up to Hardox 600 and specialized grades like Hardox HiTuf) has set global standards for quenched and tempered martensitic wear-resistant plates, the combination of high impact stress and severe sliding abrasion often demands alternative, engineered materials. High-strength bimetallic composites, such as Chromium Carbide Overlay (CCO) plates, are now integrated alongside classic quenched and tempered steels to tackle the harshest operating conditions in heavy industries like mining, metallurgy, cement processing, and power generation.
As industrial processes scale up, procurement managers and project engineers face a complex choice. Sourcing directly from verified factories with advanced metallurgic integration, R&D labs, and robust export capabilities ensures stable component lifespan. Tangshan Runxing Machinery Co., Ltd. has developed specialized CCO plates, automatic hardfacing machinery, and maintenance services that perfectly complement traditional Hardox-based steel applications, providing custom wear profiles for demanding local and international environments.
To ensure we stay at the forefront of the wear-resistance industry, our technology roadmap emphasizes three major developmental axes: metallurgical micro-structural engineering, manufacturing automation, and sustainability.
We are actively researching the addition of trace alloying elements, such as Niobium (Nb), Titanium (Ti), and Boron (B), to create complex chromium carbides. This refines carbide grains, prevents cracking under sudden thermal shifts, and matches the tough properties of martensitic Hardox steel structures.
Integration of intelligent closed-loop feedback systems in our automated welding machinery. Real-time temperature measurement dynamically adjusts arc voltage, wire feed rate, and oscillation speed to yield stress-free coatings with under 5% base plate dilution.
By transitioning key production operations to high-efficiency open-arc and laser-cladding lines, we lower carbon emissions per square meter of wear plate. Additionally, our industrial roll and grinding disk rebuilding services directly extend component lifecycles, supporting circular economy targets.
Located in the heart of China’s steel metallurgy zone in Tangshan, Hebei Province, Tangshan Runxing Machinery Co., Ltd. (founded in 2010) capitalizes on immediate access to raw materials and heavy fabrication infrastructure. As a major global steel industrial hub, Tangshan allows us to source high-grade structural plates and alloy additives efficiently, lowering logistics overheads and stabilizing production cycles.

Mine operators require components that survive severe impact and sliding wear. We provide excavator bucket liners, chute liners, and hopper protectors that endure abrasion in open-pit and underground mines globally.
Steel mills operate in high-temperature, highly corrosive environments with coarse minerals. Our hardfaced and bimetallic steel products maintain wear resistance under demanding thermal loads.
Protecting fan blades, coal pulverizer mill liners, dust collection ducts, and fuel conveyor systems from abrasive fly-ash and coal dust, extending boiler auxiliary components' operational lifecycles.
Bulk ports require reliable stackers, reclaimers, hopper systems, and transfer chutes. We offer CCO solutions that reduce maintenance during intensive vessel loading schedules.
For high-flow dry particles, we combine wear-resistant alumina ceramic elements (sintered at high temperatures) with metal backings, offering specialized erosion protection.
We are continuously researching new alloy chemistries to expand our wear protection capabilities for extreme temperatures and chemically corrosive zones.
Our technical team regularly designs custom liners using CAD and 3D modeling to match unique industrial equipment geometries.
Grinding rollers and vertical mill table disks in steel plants, cement works, and coal mills are subject to constant high-stress grinding abrasion. Runxing's advanced roll repair processes use automated build-up welding to restore worn profiles, saving companies up to 60% compared to new component costs while matching or exceeding original operational lifespans.
We design and manufacture automatic hardfacing welding machines. Featuring an integrated 10.2-inch touch-screen numeric control panel, our equipment supports up to four welding guns working simultaneously or independently. It handles solid-core, flux-cored, and self-shielded wires across open-arc and submerged arc settings, ensuring high deposition rates and uniform coatings.
Supported by our experienced engineering division, we cut, bend, and weld heavy-gauge wear plates into finished liners, complex pipes, elbows, and wear-resistant fittings. We deliver prefabricated systems ready for rapid installation, keeping onsite welding to a minimum.
Our website trials marked the launch of our digital service platform, aimed at providing global industrial buyers with access to documentation, chemical analyses, and ordering options for wear-resistant components.

Hardox is a quenched and tempered martensitic through-hardened steel plate that provides excellent impact resistance and structural strength. Chromium Carbide Overlay (CCO) is a composite structure with a mild steel backing and a wear-resistant hardfacing overlay containing primary chromium carbides. While Hardox typically averages 400 to 600 Brinell hardness (HBW), CCO overlays exhibit micro-hardnesses exceeding 1500 HV (equivalent to 60-65 HRC). Under severe sliding abrasion and low-to-medium impact, CCO plates can outlast traditional quenched and tempered plates by up to 5 to 8 times.
Runxing RX®wp 7600 plates feature high concentrations of Chromium (Cr: 25-35%) and Carbon (C: 4-5.5%) deposited on a structural steel substrate (like Q235B or Q355B). The resulting weld overlay contains a high density of primary M7C3 hexagonal chromium carbides. The hard carbide phases are embedded in an austenitic matrix, which supports the hard particles and absorbs impact stress.
Surface check-cracks (also known as relief cracks) are normal in bimetallic CCO plates. They form during the overlay cooling process to relieve thermal stresses, preventing distortion of the plate. These cracks only run through the hardfaced overlay layer and stop at the ductile carbon steel backing plate. They do not reduce the plate's wear resistance or structural stability.
Yes. The ductile carbon steel backing allows CCO plates to be cold-formed or rolled into complex shapes, such as pipe segments, chutes, and hopper curves. Roll forming should align with the welding bead direction to prevent cracking. Welding is done on the backing plate side using conventional low-carbon electrodes (like E7018), while the hardfaced side is typically filled using hardfacing wire to maintain wear protection at joints.
Standard chromium carbide overlay plates maintain their hardness up to 350°C (660°F). For higher temperature operations, such as steel blast furnace chutes or cement kiln parts, specialized high-temperature alloys containing elements like Niobium, Tungsten, or Boron are used, raising the thermal limit to 550°C-800°C.
