Read DetailsIn modern industrial manufacturing, heavy mechanical systems operate under severe conditions involving high friction, extreme impact, chemical corrosion, and intense heat. Components in mining operations, cement mills, steel production, and power generation are subject to continuous surface degradation. Stainless steel flux cored wires (SS FCW) and hardfacing materials have become critical solutions to combat these engineering challenges. Unlike solid wires, flux cored wires are filled with specific metallic powders, slag-forming agents, and deoxidizers that improve arc stability, deposition rates, and the metallurgical properties of the welded surface.
The global demand for high-performance welding consumables is driven by the need for operational efficiency. Industries are transitioning from replacing worn machinery to repairing and overlaying surfaces with high-performance alloys. Hardfacing—the process of applying wear-resistant cladding to structural steel backings—extends the life of industrial parts by up to 500%. Using chromium-carbide overlays (CCO) or martensitic stainless steel cladding allows enterprises to minimize downtime, reduce capital expenditure, and maintain high production yields.
Stainless steel flux cored wires utilize a hollow tubular wire configuration containing granular core elements. The metallurgical design ensures optimal performance during the welding process:
Procuring raw welding consumables and wear plates requires strict quality control, cost management, and timely delivery. Large-scale industrial procurement departments must prioritize the reliability and technical compliance of their suppliers. As a manufacturer located in China's industrial base, Tangshan Runxing Machinery Co., Ltd. partners with Hebei Yuwan International Trade Co., Ltd. to manage the complete export workflow, including customs clearances, international ocean freight, and compliant banking transactions. This allows our manufacturing plant to focus entirely on R&D, quality assurance, and automated fabrication, ensuring that every batch of flux cored wire meets global standards like DIN 8555 and AWS A5.22.
A trusted industrial pioneer specializing in hardfacing R&D and wear-resistant materials
Founded in 2010 in Tangshan, Hebei Province, Tangshan Runxing Machinery Co., Ltd. is a professional manufacturer focused on the research, development, production, and on-site construction of hardfacing wear-resistant metal products. Our advanced facilities and mature metallurgical surface technologies allow us to deliver cost-effective wear protection systems globally.
Our main products include chromium carbide overlay (CCO) wear plates, custom processed wear liners, wear-resistant pipes, hardfacing flux-cored welding wires, and automatic hardfacing welding machines. Additionally, we provide professional roller surfacing repair services to restore worn equipment to original operating standards. Over the last decade, we have established ourselves as a qualified agent for Germany's renowned VAUTID brand for six consecutive years, illustrating our dedication to high-quality materials and metallurgical integrity.
We work closely with global heavy industries, providing customized wear solutions for cement plants, mining mills, steel companies, coal-fired power facilities, and dredging operations. Our export activities are fully authorized and managed by Hebei Yuwan International Trade Co., Ltd., ensuring compliance, secure payment processing, and timely logistics support across Russia, Central Asia, South America, and Africa.
Engineered systems developed for the most demanding working conditions
Critical systems like vertical mill rolls, table liners, and discharge chutes experience intense abrasion. Hardfacing extends equipment run times and stabilizes production output.
Heavy ore handling, screening decks, and excavating buckets suffer under extreme impact and wear. Our CCO wear plates protect truck beds and chutes from structural loss.
Sintering plants, coke ovens, and hot blast furnace components run under combined thermal load and abrasion. Our alloy overlays preserve surfaces at elevated temperatures.
Coal pulverizer rolls, exhaust fans, and dry ash disposal pipelines require continuous wear shielding to prevent unexpected shutdowns and boiler tube damage.
Bulk mineral transshipment ports require wear protection on grab buckets, transfer hoppers, and stacker-reclaimer liners to handle high volume flow rates.
High-purity, sintered alumina ceramics provide protection in pneumatic conveying lines where friction-induced wear dominates metal loss mechanisms.
Ongoing material design focused on high-entropy alloys (HEAs) and nanostructured flux cored wires for next-generation industrial applications.
On-site inspection, wear mapping, and customized cladding repair designs implemented by Runxing's specialized engineering teams.
The industrial surface engineering landscape is evolving rapidly. Traditional chromium-iron (Cr-Fe) cladding systems, while effective, are reaching their performance limits in high-speed, high-temperature, and corrosive working environments. Runxing's metallurgical R&D department is actively pursuing several development trajectories to address these challenges:
By incorporating micro-additions of strong boride and nitride-forming elements, such as Titanium (Ti), Niobium (Nb), and Zirconium (Zr), we can refine the chromium carbide grain size during weld metal solidification. Refined primary carbides reduce brittle fractures and edge chipping under heavy loading, which increases the impact resistance of bimetallic wear plates without compromising macro-hardness.
For applications in steel mill continuous casting rolls and waste incineration boilers, thermal fatigue resistance is critical. Traditional cobalt-based alloys (e.g., Stellite types) are expensive and subject to market volatility. Runxing is developing high-alloy nickel-chromium-iron matrix wires containing complex carbide distributions to match the hot-hardness of cobalt-based overlays at a lower cost.
As modern factories adopt Industry 4.0 models, manual welding is being replaced by robotic and CNC surfacing setups. Our RX® Surfacing equipment utilizes automated PLC controls, uniform speed swing mechanisms, and multiple torch configurations. These systems integrate with our proprietary flux cored wires, controlling heat input to reduce base metal dilution and yield a consistent, high-hardness surface in a single pass.
Our quality management system controls all production steps, from raw mineral powder inspection to final spool and wear plate testing.
Our chromium carbide wear overlays are subjected to dry sand/rubber wheel abrasion tests to guarantee wear performance under pressure.
Global contracts are executed through Hebei Yuwan International Trade, ensuring secure international logistics and payment terms.

Our CCO wear plates (such as the RX®wp 7600 series) are manufactured using open-arc welding to apply a thick chromium carbide layer onto a structural carbon steel backing. The typical chemical composition of the overlay consists of 3.5% to 5.5% Carbon (C) and 25% to 35% Chromium (Cr). This metallurgical composition yields a hardness rating of 58 to 62 HRC, which provides resistance to heavy abrasive wear.
Self-shielded flux cored wire contains chemical compounds within its core that vaporize under the welding arc, creating a localized shielding gas envelope. This eliminates the need for external gas cylinders (such as CO2 or Argon/CO2 mixes), making self-shielded wire suitable for outdoor maintenance, field repairs, and high-wind environments where external gas shields can dissipate.
Hebei Yuwan International Trade Co., Ltd. is our fully authorized export trading partner. This business model allows our manufacturing plant in Tangshan to focus on technical development, production quality, and schedule management, while Yuwan Trade handles commercial steps including customs clearance, ocean shipping logistics, documentation, and payment processing.
Yes, we provide custom processing services. We can cut, bend, roll, weld, and pre-drill our chromium carbide overlay plates according to your CAD drawings. Our fabrication facility uses plasma cutting and rolling systems to supply finished liners that can be directly bolted or welded into your chutes, buckets, and hoppers.
The fine transverse cracks on the carbide overlay surface are stress-relief cracks. They form naturally during the cooling phase of the weld cladding process due to the differences in thermal contraction rates between the carbide overlay and the structural steel backing. These cracks do not compromise the plate's performance; instead, they relieve residual stress and prevent the plate from warping during installation and operation.
