Runxing Machinery is dedicated to offering custom ODM solutions, bimetallic chromium carbide overlays, and hardfacing materials designed to meet the demands of severe wear operations globally. This whitepaper provides a comprehensive review of key industry trends, global supply challenges, chemical overlay dynamics, and localized solutions.
Heavy machinery utilized in mining and processing facilities is exposed to extreme stresses. Standard mild steel and even quenching-and-tempering carbon plates are insufficient for handling aggressive mineral friction, high drop impacts, and chemical corrosion. Custom-engineered bimetallic wear solutions utilize a dual-layer strategy: a high-ductility structural backing plate (typically Q235B or Q345B) that absorbs structural shock loads and a hardfaced overlay layer rich in chromium carbides that provides superior abrasion resistance.
Through precise control of the heat-affected zone (HAZ) and minimal base-metal dilution during the welding process, modern factories deliver plates with hardness ratings exceeding 60 HRC, retaining structural durability and preventing catastrophic crack propagation during operation.
The global mining sector is shifting towards maximizing equipment uptime and reducing carbon footprint per ton of extracted material. These shifts drive technical design priorities in three ways:
Procuring wear materials is a critical task for global mineral processing groups. Operations are typically located in remote regions (such as Central Asia, Western Australia, the South American Andes, or Sub-Saharan Africa), making supply delays highly disruptive.
Purchasing departments require partners that offer both manufacturing capabilities and reliable global trade execution. Runxing Machinery manages export processes through Hebei Yuwan International Trade Co., Ltd., which coordinates customs clearance, maritime logistics, and global settlements. This division of labor allows our manufacturing facilities to focus on quality control and raw material metallurgy, while ensuring reliable deliveries to international ports and job sites.
The abrasion resistance of CCO wear plates depends on the volume and orientation of the primary Cr7C3 carbides. Our automated open-arc weld deposition maintains a carbide volume fraction of 30% to 50%, with primary carbides aligned perpendicular to the sliding wear surface. This microstructural configuration provides superior protection compared to manual weld build-ups or conventional casting techniques.

Tangshan Runxing Machinery Co., Ltd., founded in 2010, is a professional manufacturer based in Tangshan, Hebei Province. We focus on the R&D, production, and on-site construction of hardfacing wear-resistant metal products. Our main offerings include chromium carbide overlay (CCO) wear plates, custom-processed wear liners, wear-resistant pipes and fittings, hardfacing flux-cored welding wires, automatic hardfacing welding machines, and professional roller surfacing repair services.
We provide customized wear-resistant solutions globally, serving the cement, steel, mining, port, and dredging industries. To streamline international distribution, all export logistics, customs clearance, and global collections are managed through our authorized trading partner, Hebei Yuwan International Trade Co., Ltd., enabling our manufacturing teams to focus on quality assurance and production scheduling.
Our wear-resistant products are applied across heavy industries, improving component lifespans in demanding working conditions.
The availability of critical equipment is key to cement plant productivity. Our wear-resistant plates and liners are used in raw material feed chutes, cyclones, separator guide vanes, and raw mill rollers, helping protect components against heavy sliding friction and heat.
Mine operators require wear solutions that reduce maintenance intervals for excavators, loader buckets, truck beds, and sizing screens. Runxing designs custom liners to match local mineral abrasive profiles, extending service life in severe environments.
The steel industry presents demanding operating environments involving high temperatures, heavy loads, and corrosive gases. Our alloy overlays are designed to maintain hardness and resist thermal fatigue in applications like coke chutes and sinter screens.
We provide wear protection for critical pulverized coal processing equipment, including exhauster fan blades, conveyor chutes, coal hopper liners, crushers, and dust collection systems, helping reduce auxiliary power losses and system leaks.
Port operations handle high volumes of abrasive dry bulk goods. We manufacture liners for ship loaders, clamshell buckets, and receiving hoppers, helping to minimize metal wear and prevent operational slowdowns during transshipment.
For high-velocity sliding abrasion and fine-particle slurries where impact forces are low, we supply high-purity, sintered alumina ceramic liners that provide high surface hardness and chemical inertness.
Extending the service life of vertical roller mills (VRM) and roller presses via automated on-site and in-shop hardfacing processes, reducing overall capital expenditures for cement and steel producers.
Custom fabricated pipelines, bends, elbows, and T-junctions lined with chromium carbide weld deposits, designed for transporting highly abrasive mining slurries and pneumatic pulverized coal.

Find answers to common technical and logistical questions regarding bimetallic overlays, welding consumables, and international shipping.
A: Bimetallic CCO plates consist of a carbon steel backing and a hardfaced overlay containing primary chromium carbides (Cr7C3). While quenched steel plates like AR500 offer hardness values of 45-50 HRC throughout their thickness, our CCO plates achieve surface hardness values of 58-62 HRC. This microstructural configuration provides superior resistance to high-stress sliding abrasion, typically extending the service life of components by 3 to 5 times compared to standard carbon steels.
A: Yes. The carbon steel backing plate (such as Q235B or Q345B) provides structural ductility, allowing the plates to be welded to existing equipment using conventional low-hydrogen electrodes. The plates can be plasma cut from the backing side and roll-formed to fit curved surfaces, with the overlay on either the inside or outside radius depending on the application.
A: Our hardfacing flux-cored welding wires comply with DIN 8555 standards. Depending on the specific grade (e.g., MSG 10-GF-60-G), they deposit high-alloy overlays rich in chromium, carbon, and other micro-alloys, designed to resist grinding wear, impact loads, or high-temperature erosion.
A: All international export trade, customs clearance, shipping documentation, and financial settlements are managed by Hebei Yuwan International Trade Co., Ltd. This specialized arrangement allows our production team in Tangshan to focus on quality control and manufacturing schedules while ensuring compliant deliveries to global ports.
A: Runxing has been an authorized partner and agent for VAUTID since 2019. We utilize VAUTID welding consumables in our premium overlay products, combining European metallurgical designs with our automated, high-volume manufacturing capabilities to produce consistent wear solutions.
A: Material selection depends on operating factors such as mineral type, particle size, fall heights, operating temperatures, and chemical exposure. Our engineering team can analyze your operational parameters to recommend an optimal backing-to-overlay ratio (e.g., 6+4, 8+6, or 10+10) and alloy formulation.
