Examine Specifications >In modern industrial operations, degradation of mechanical components through wear, friction, and impact accounts for billions of dollars in losses annually. To mitigate this, hardfacing—the application of a wear-resistant alloy coating to the surface of a carbon steel base—has emerged as a foundational engineering practice. Among the options available, flux-cored welding wire (FCAW-H) stands at the forefront of wear-resistant surface engineering, outperforming solid wires and stick electrodes in deposition rate, metallurgical precision, and versatility.
By utilizing a tubular wire filled with a precise mixture of alloying elements, deoxidizers, and slag-formers, flux-cored technology enables manufacturers to customize the chemistry of the weld deposit. Whether shielding with external gas (dual-shield) or relying on internal vaporizing compounds (self-shielded/gasless), FCAW allows for high-efficiency deposition, making it the preferred choice for manufacturing facilities, automated cladding workshops, and on-site repair crews worldwide.
Our comprehensive product lineup is designed to address a wide range of industrial wear challenges, from pure dry abrasion to high-impact pounding. Below is a detailed technical examination of our core systems.
Consisting of a structural steel backing plate (e.g., Q235B) surfaced with a high-chromium weld overlay. These plates offer excellent resistance to abrasive slide wear. The primary carbide phase (Cr7C3) features hardness values up to 1500 HV, while the steel backing allows for easy cutting, rolling, and welding into shape.
Engineered with internal gas-generating elements, these wires require no external shielding gas, making them ideal for outdoor and wind-exposed operations. Formulations like our RX-wp 7600 wire series are optimized to resist porosity and slag inclusion during open-arc field application.
Plasma Transferred Tungsten Arc (PTTA) surfacing materials and equipment provide ultra-low dilution control, minimal heat-affected zones (HAZ), and highly concentrated wear protective surfaces. Essential for high-precision components like critical valve surfaces and high-stress extruder screws.
| Alloy Classification | Hardness Range (HRC) | Primary Chemical Composition (%) | Best Application Match | DIN 8555 Equivalent |
|---|---|---|---|---|
| High Chromium Iron | 58 - 65 HRC | C: 3.5 - 5.5% | Cr: 22 - 32% | Severe sliding abrasion & low impact | MF10-GF-60-GR |
| Complex Carbide (Cr-Mo-W-V) | 60 - 67 HRC | C: 4.0% | Cr: 22% | Mo: 6.0% | W: 2.0% | High temp abrasion (up to 650°C) | MF10-GF-65-GTR |
| Martensitic Steel | 48 - 56 HRC | C: 0.5% | Cr: 5.0% | Mo: 1.5% | Metal-to-metal wear, medium impact | MF6-GF-55-GP |
| Austenitic Manganese | 20 - 55 HRC (Work hardens) | C: 0.8% | Mn: 14% | Cr: 4.0% | Extreme pounding impact, rock crushers | MF8-GF-200-KP |
The performance of hardfaced layers determines the operating time of critical equipment. Below, we detail specific application scenarios where our flux-cored wires and CCO plates extend equipment life:
Raw materials like limestone and clinker cause rapid slide abrasion. Standard carbon steel chutes wear out in months. Upgrading to our Chromium Carbide Overlay (CCO) plates extending lifetime by up to 5-8x, reducing plant maintenance shutdowns.
Mine operators seek to increase productivity under extreme impact. Using our high-hardness, self-shielded open-arc flux-cored wires allows on-site welders to build up shovel bucket lips, dragline buckets, and haul truck liners directly in the field.
Steel production environment involves high temperatures and corrosion. Hardfacing sinter star crushers and hot guide rollers with specialized Mo-W containing complex carbide wires guarantees hardness retention at temperatures exceeding 600°C.
Coal pulverizers, vertical mills, fan blades, and separator bodies are subject to constant air-borne dust erosion. Application of thin CCO plates (e.g. 4+4 or 6+4 thickness profiles) maximizes protection without overloading fan assemblies.
Bulk transport of sand, iron ore, and minerals destroys receiving hoppers and chute walls. Bimetallic plates and automated hardfacing wire overlays provide the corrosion and abrasion resistance required to withstand salt spray and wet slurries.
For high-velocity slurry lines with low impact requirements, we engineer alumina-ceramic wear-resistant hybrid steel linings to ensure complete erosion protection under the most critical continuous fluid flows.
Sourcing hardfacing alloys directly from our manufacturing facility in Tangshan, Hebei Province—the steelmaking heartland of China—unlocks strategic cost and logistical advantages for global enterprises.
Direct proximity to core high-purity iron ore, chromium, and alloy refineries lowers base manufacturing costs.
Collaborative research with Tangshan University ensures optimal control over carbide particle distribution.
High-volume production lines produce over 12,000 tons of flux-cored wire annually, ensuring consistent batch control.
Structured export management by Hebei Yuwan International Trade Co., Ltd. handles customs and multi-modal freight.
Our integration with local metallurgical suppliers allows us to bypass middlemen. We control the entire chemical composition process, from raw ferroalloy powders to drawing the finished steel casing. This raw material security protects our clients from global supply shocks and guarantees stable price agreements for high-volume supply contracts.
Global industrial purchasing requires strict adherence to international testing standards and third-party certifications. To ensure reliable performance in demanding environments, we follow standard QA and export procedures:
To protect against degradation from humidity, our flux-cored wires are packed in vacuum-sealed aluminum bags with desiccant, protected by plastic spools or steel basket rings, and loaded onto export-ready wooden pallets.
Recognizing the operational complexities of international procurement, Tangshan Runxing Machinery Co., Ltd. has established a streamlined division of labor:
We provide complete documentation for every shipment, including Mill Test Certificates (MTC), Certificate of Origin (Form E/Form F as applicable), Detailed Packing Lists, and Bill of Lading. This structure ensures fast customs clearance and transparent payment processing via global trade channels.
