With major mining developments in the Andean region (focusing on gold, copper, and the surging lithium brine extraction projects in Salta, Jujuy, and Catamarca), wear protection is no longer a standard maintenance task—it is a critical economic driver. Processing highly abrasive silica-rich ores, salt crusts, and hard rock requires hardfacing materials that significantly extend component lifespans.
Additionally, the cement hubs in Buenos Aires Province and Olavarría, alongside the steel mills in Villa Constitución and San Nicolás, face continuous operational wear. In these industries, equipment downtime is exceptionally costly. By sourcing directly from a top-tier Chinese welding wire factory with dedicated logistics capability, Argentine sourcing managers can achieve substantial cost-per-ton savings while assuring microstructural material compliance.
In high-altitude Andean environments, thermal cycling and severe impact combine with abrasive wear. Standard structural steel plates wear out in months. Our Chromium Carbide Overlay (CCO) Wear Plates utilize a hypereutectic microstructure where primary chromium carbides (M7C3) are oriented perpendicular to the wear surface, yielding a service life up to 12 times longer than mild steel.
| Alloy Class | Hardness (HRC) | Primary Wear Mechanism | Argentine Application Case |
|---|---|---|---|
| Fe-Cr-C Complex | 58 - 62 | Extreme Abrasion, Low Impact | Cement Chutes, Hopper Liners |
| High Boron Fe-Alloy | 60 - 65 | Fine Particle Sliding Abrasion | Lithium Slurry Impellers |
| Nickel-based Tungsten Carbide | > 65 (WC phase) | Corrosive Abrasion | Vaca Muerta Drilling Stabilizers |
Understanding the microstructural science behind Runxing's hardfacing consumables and composite plates.
The performance of a hardfacing layer depends not only on bulk hardness, but on the size, distribution, and chemistry of the microscopic hard phases. In our chromium carbide overlay (CCO) wear plates, the deposit chemistry is meticulously controlled using high-purity raw materials. Our proprietary flux formulas yield a hypereutectic structure with a high density of primary Cr7C3 hexagonal carbides embedded in a tough eutectic matrix.
When applying our self-shielded flux cored wires, the core contains specific deoxidizers and denitrifiers (such as titanium, aluminum, and zirconium). These elements form a protective slag and gas shield around the arc, eliminating the requirement for external carbon dioxide or argon gases. This enables seamless, high-speed repair works on mineral crushers and high-impact excavator buckets right in the high-wind fields of Patagonian mines.
Through our technical partnership with the Metal Materials and Forming Technology team at Tangshan University, we continue to develop nano-structured complex carbide alloys that offer enhanced toughness, preventing micro-spalling in high-impact drop zones.

All of our wear plates and welding wires are engineered in compliance with international standards, notably German DIN 8555 (e.g., MSG 10-GF-60-G classification for our chromium-carbide wires) and ASTM G65 procedures for measuring abrasion resistance. We maintain strict ISO 9001 quality certificates for all production processes.
Our designated export branch, Hebei Yuwan International Trade Co., Ltd., handles the complete shipping process. We organize freight from Tianjin Port directly to Buenos Aires Port, managing customs documentation, bills of lading, and certificate packages to ensure smooth clearance.
In outdoor operations—particularly in the windy regions of southern Argentina and high-altitude mining sites—gas shields can be disrupted by wind. This leads to porosity and compromises weld integrity. Self-shielded flux-cored wires generate their own protective atmosphere from the core composition, assuring sound, porosity-free weld deposits without external gas cylinders.
Yes. Our engineering division utilizes high-precision CNC plasma cutting, waterjet cutting, and rolling machines to shape wear plates to your specific drawing specifications. The plates can be rolled into conveyor pipe shapes or curved to fit specific chute geometries, ready for direct bolt-in or weld-in installation.
Our RX®wp 7600 plates feature a carbon content between 4.0% to 5.2% and chromium between 24% to 32%. This chemistry yields a high concentration of primary chromium carbides in a tough martensitic matrix, maintaining a consistent surface hardness of 58 to 62 HRC over the entire wear deposit thickness.
We supply both the specialized high-hardness rebuilding wires (such as complex alloys with added niobium or boron) and automated surfacing equipment.
