Explore Specifications >Industrial machinery operating in cement, mining, steel production, and power generation experiences severe physical degradation through abrasive wear. Standard structural steel, regardless of simple heat treatments, cannot withstand continuous sliding and grinding abrasion from minerals, clinker, coal, or slag. To prevent catastrophic failure and reduce high replacement costs, materials engineers utilize Chromium Carbide Overlay (CCO) wear plates.
A CCO wear plate is a bimetallic composite consisting of a standard structural backing steel plate (typically Q235B or Q355) and an ultra-hard alloy overlay welded using open-arc or submerged-arc techniques. The chemistry of the overlay is high in carbon (3.0% to 5.5%) and chromium (22% to 35%).
"During the solidification process, primary M7C3 chromium carbides form within a tough, wear-resistant eutectic matrix. The microscopic hardness of these carbides ranges from 1200 to 1600 HV, providing a bulk hardness of 58 to 62 HRC."
This unique microstructure ensures that the hard chromium carbides bear the abrasive forces while the resilient steel backing plate absorbs mechanical shock and stress, allowing for easy welding, bolt-hole cutting, and structural fabrication.
Standard heat-treated steel achieves hardness through martensitic structures, which soften under high-temperature friction. CCO plates maintain their primary chromium carbide crystalline structure, preventing plastic deformation and micro-cutting from abrasive particles even at temperatures up to 600°C.
Our overlay materials comply strictly with the DIN 8555 standardization system, classing under Group 10 (Fe-Cr-C alloys) designed for high abrasion resistant surfacing overlays, ensuring consistent mechanical behavior in harsh applications.
Founded in 2010 in Tangshan, Hebei Province—the steelmaking heartland of China—Tangshan Runxing Machinery Co., Ltd. has developed into a leading authority in research, development, and production of industrial wear solutions.
Through our long-standing partnership with the metallurgical research teams at Tangshan University—led by Dean Yuan Shaoqiang, Vice Dean Li Jing, and Professor Yang Yuehui (Team Leader of Metal Materials and Forming Technology)—Runxing constantly advances wear plate chemistry. This academic-industry integration ensures that our surfacing alloy formulas meet high standards of performance.
For six consecutive years since 2019, Runxing Machinery has been recognized as a qualified agent and strategic partner for VAUTID (Germany). By utilizing premium VAUTID chemical recipes and raw components alongside our proprietary processes, we manufacture CCO plates and hardfacing consumables that rival European brands in durability and toughness.
All export business is fully authorized and handled by Hebei Yuwan International Trade Co., Ltd. This dedicated trading partner manages customs clearance, global shipping, trade documents, and flexible payment terms, allowing our factory team to focus entirely on quality assurance and on-time order fulfillment.
China is the world's largest producer of steel and high-carbon ferrochrome, offering Runxing Machinery unmatched supply chain advantages. Our location in Hebei Province allows us to procure raw steel backing plates and alloying elements with minimal logistics delays, transferring this cost-efficiency directly to our international clients.
Our factory utilizes advanced 4-Gun CNC automated surfacing equipment. Operating via a 10.2-inch interactive touch screen, these units control the speed and amplitude of the welding torch to deposit overlay layers with minimal heat input, minimizing distortion in the backing plate.
Whether utilizing solid-core, open-arc, gas-shielded, or submerged-arc flux-cored wires, our automated machines adjust parameter variables dynamically. The result is a highly uniform bead pattern with a low dilution rate, ensuring that the target hardness is achieved from the first millimeter of the overlay.
Our wear-resistant solutions are engineered to withstand the most demanding operating conditions in heavy industry.
Wear resistance is crucial for cement plant run-times. We supply CCO plates for raw meal chutes, separators, and hopper liners, along with mill roller repair.

Lower-quality overlays with uneven hardness profiles or high dilution rates wear through prematurely, leading to unplanned downtime and high replacement costs.
Runxing Machinery employs a comprehensive Quality Management System (QMS) covering every stage of production: raw material inspection, weld parameter logging, hardness profiling, and dimensional verification. This process guarantees that every CCO plate meets our strict quality guidelines before leaving the factory.
"Through Hebei Yuwan International Trade Co., Ltd., we offer FOB, CIF, DDP, and CFR shipping arrangements, backed by complete documentation including mill test certificates, chemical analysis reports, and UT testing records."
We perform scanning electron microscopy and optical metallography tests on production batches to verify that primary M7C3 chromium carbides are oriented perpendicular to the wear surface, maximizing abrasion resistance.
We test bulk hardness using ASTM G65 dry sand rubber wheel test methods, ensuring hardness values remain consistent within 58-62 HRC across the entire plate thickness.
Technical answers to key questions about wear plate selection, fabrication, and performance optimization.
Our standard Chromium Carbide Overlay (CCO) plates, including the RX®wp 7600 series, feature a surface hardness range of 58 to 62 HRC (650–800 HV). This range is optimized to balance extreme abrasion resistance with sufficient fracture toughness, preventing premature cracking under light-to-moderate impact conditions.
The hairline relief cracks on the overlay surface are normal and develop during the cooling process to relieve thermal stresses. They only affect the overlay layer and do not penetrate the structural backing plate. These cracks do not compromise the plate's wear resistance or structural integrity.
Yes, our plates are designed for versatile shop fabrication. They can be cut using plasma arc, laser, or waterjet systems (cutting from the carbon steel backing side). They can also be rolled or bent using standard press brakes, with the overlay on either the inside or outside radius depending on the application.
Self-shielded flux-cored wire (such as our OEM hardfacing wires) contains slag-forming and gas-generating agents within the flux core. This eliminates the need for external shielding gas cylinders, making it ideal for outdoor repairs, high-wind job sites, and field maintenance where gas setups are impractical.
Our CNC 4-gun automated surfacing system ensures uniform weld bead deposit profiles and consistent penetration depth. Controlling the heat input reduces dilution from the base metal, ensuring high chromium carbide density throughout the overlay layer.
Hebei Yuwan International Trade Co., Ltd. handles all export operations for Runxing Machinery, including customs declaration, logistics booking, Certificate of Origin issuance, and payment processing. This ensures efficient delivery and clear documentation for our global buyers.
Yes, our metallurgical team, in partnership with Tangshan University, can customize the chromium, carbon, niobium, and boron ratios to meet specific wear, temperature, or chemical requirements.
Depending on application conditions, our CCO wear plates can extend service life by 5 to 15 times compared to mild carbon steels, and by 3 to 4 times compared to standard quenched and tempered AR400/500 plates.
