Alloy Formulations >Uruguay's industrial footprint is experiencing a profound modernization phase, driven by the expansion of its pulp and paper production, bulk agricultural exports, port facilities, and cement manufacturing. Major installations, such as the UPM pulp mills and the busy shipping terminals along the Uruguay and Paraná rivers, process millions of tons of coarse wood chips, grains, minerals, and clinker annually. This massive logistical and processing flow subjects transport infrastructure—specifically chutes, hoppers, screw conveyors, and bulk storage silos—to continuous, high-stress sliding abrasion and impact fatigue.
In the agricultural export hub of Nueva Palmira and the port facilities of Montevideo, grain-handling chutes face continuous wear from friction. Standard structural carbon steels (such as ASTM A36) or conventional quenched and tempered wear steels wear down rapidly under these relentless workflows. The consequence is unscheduled downtime, elevated maintenance expenditures, and decreased system safety. By introducing advanced Chromium Carbide Overlay (CCO) wear plates, Uruguayan enterprises can extend the service life of their material handling elements by 5 to 10 times compared to standard steels, generating a direct positive effect on operating margins.
Additionally, the quarrying and cement production sectors in locations like Minas and Paysandú deal with highly abrasive limestone and silica-rich minerals. Excavator buckets, primary crushers, and vertical roller mill housings in these regions require robust protection. Installing high-performance bimetallic wear plates ensures that these critical machines run uninterrupted during peak demand periods, boosting production efficiency across Uruguay's mineral sector.
At the center of Tangshan Runxing Machinery’s engineering philosophy is the optimization of microstructure. The performance of Chromium Carbide Overlay (CCO) plates is determined by the volume fraction and spatial distribution of primary M7C3 chromium carbides within a tough austenitic matrix. Unlike generic wear plates, our production lines utilize specialized, automated open-arc surfacing systems. This process maintains tight thermal control to produce a high density of primary chromium carbides (with chemical composition typically ranging between 4.0% to 5.5% Carbon and 25% to 35% Chromium).
| Product Line | Typical Hardness (HRC) | Alloy Composition | Primary Application in Uruguay |
|---|---|---|---|
| RX®wp 7600 (DIN 8555) | 58 - 62 | C: 4.5-5.0%, Cr: 28-32%, Fe: Bal. | Wood chip chutes, grain silos, mining hopper liners |
| High-Hardness CCO | 60 - 64 | C: 5.0-5.5%, Cr: 30-35%, Nb/V additions | Cement vertical mill housings, clinker chutes |
| Self-Shielded Flux Cored Wire | 57 - 61 | C: 4.0-4.8%, Cr: 25-30% | On-site bucket rebuilding, weld repairs in Montevideo |
During the cladding process, we maintain rigid quality controls to ensure the weld bead conforms strictly to DIN 8555 standards. Our proprietary flux-cored wire formulations ensure minimal dilution from the mild steel backing plate, preserving high chromium content throughout the wear layer. In accordance with ASTM G65 Procedure A dry sand rubber wheel abrasion tests, Runxing CCO wear plates show minimal volume loss compared to QT400/500 steels. This translates into reliable, predictable wear performance in high-friction environments.
"The presence of well-dispersed hexagonal M7C3 carbides with micro-hardness values exceeding 1500 HV provides the primary defense against abrasion, while the ductile steel base absorbs the mechanical impacts common in mining and cement handling."

Chromium Carbide Overlay (CCO) plates, such as our RX®wp 7600, feature a hardfacing weld overlay containing primary chromium carbides. While traditional Quenched and Tempered (AR) steels rely on martensitic hardness (typically 400-500 HBW) throughout the plate thickness, CCO plates provide a much harder wear surface (HRC 58-62). In sliding abrasion applications like wood chip conveyor chutes, CCO plates can outlast traditional AR plates by up to 5-10 times, reducing maintenance frequency and overall costs.
Yes. Runxing bimetallic plates feature a weldable mild steel backing (such as Q235B or ASTM A36), which allows them to be welded directly onto steel structures using standard structural welding consumables. The plates can be cut using plasma arc cutting systems (cutting from the backing side toward the overlay). They can also be cold-formed or rolled using heavy bending rolls to conform to curved surfaces, such as chute profiles or pipe geometries.
Tangshan Runxing Machinery Co., Ltd. is the dedicated manufacturing plant and R&D center focused on hardfacing metal production. All international trading, export handling, customs declarations, shipping logistics, and payment collection are fully authorized and managed by Hebei Yuwan International Trade Co., Ltd. This division of labor allows the factory to focus on product quality and scheduled production, while providing customers with professional and secure export services.
We implement quality control checks throughout the production cycle. Every batch of wear plates undergoes surface hardness mapping (ensuring HRC 58-62), thickness verification (both backing and overlay dimensions), and flat alignment checks. Upon customer request, we also perform microstructure analysis to verify the volume fraction and even distribution of M7C3 primary carbides, and provide Mill Test Certificates (MTC) detailing chemical composition.
Self-shielded flux-cored wire is designed for on-site repair and rebuild work where providing gas shielding (such as argon or CO2) is difficult, such as outdoor industrial locations, ports, and quarries. The wire chemistry produces its own protective atmosphere during the arc process, allowing field technicians in Uruguay to rebuild bucket edges, draglines, and transport elements quickly and effectively.
