In the modern heavy industry sector, mechanical wear accounts for over 50% of unexpected downtime in mineral processing, raw material handling, and steel production. Unscheduled maintenance cycles not only restrict production capacities but also generate high secondary costs related to structural failure, labor intensive component replacement, and supply chain bottlenecks. To combat these losses, heavy industries have shifted from traditional sacrificial metals to advanced surface engineering. Central to this paradigm shift is the application of hypereutectic Chromium Carbide Overlays (CCO) and high-performance MIG welding hardfacing materials.
Global demand for high-strength wear plates and hardfacing MIG wires has accelerated, fueled by international infrastructure developments and heavy mining expansions. The procurement patterns of multi-national enterprises indicate a clear prioritization of material longevity over initial purchase costs. Choosing a wholesale supplier that provides certified metallurgical testing, consistent wear performance under ASTM G65 standards, and robust logistical integration has become a strategic necessity for engineering firms, procurement offices, and plant managers worldwide.
“Strategic material sourcing is no longer about finding the cheapest electrode; it is about evaluating the microstructural carbide density and dilution factors to secure the lowest possible Total Cost of Ownership (TCO).”
The core technology behind our high-performance wear plate product line lies in the controlled precipitation of primary chromium carbides (M7C3) within a tough, iron-rich matrix. When standard structural steel (such as Q235B or Q355) is surfaced with our high-chromium welding wire using open-arc or submerged-arc processes, the resulting overlay chemistry achieves a chromium content typically ranging from 25% to 40%, with a carbon volume of 3.5% to 5.5%. Under precise cooling rates, these components form hexagonal primary M7C3 carbides with a microhardness exceeding 1200 HV, oriented perpendicular to the wear surface.
This microstructural configuration provides superior resistance to severe scratching abrasion. The ductile matrix surrounding the hard carbides absorbs moderate impacts, preventing rapid chipping and structural spalling. In contrast to conventional quenched steel plates, which lose hardness when exposed to elevated operating temperatures, our CCO wear plates maintain their wear-resistant properties up to 600°C, making them critical for flue gas ducts, steel plant sinter systems, and cement mill discharge gates.
For operations involving on-site repairs or manufacturing of complex structural geometries, hardfacing flux-cored MIG wires present an agile and highly efficient solution. Unlike solid welding wires, flux-cored wires are filled with a precise blend of metallic powders, deoxidizers, and slag-forming compounds. Our self-shielded flux-cored wires (open arc) contain specialized gas-generating agents that react during the arc process to create a local protective shield, removing the requirement for pressurized shielding gas cylinders. This makes them ideal for outdoor work, high-altitude maintenance, and windy job sites where gas shielding would dissipate, ensuring stable metal transfer, minimal spatter, and high deposition rates.
Tangshan Runxing Machinery Co., Ltd. is a specialized manufacturer located in Tangshan, Hebei Province—the heart of China's heavy industrial and steel production corridor. Established in 2010, the company has focused its corporate mission on the research, development, production, and on-site application of high-performance metal hardfacing products.
Over more than a decade of development, Runxing has expanded its core competencies to include chromium carbide overlay (CCO) wear plates, custom fabricated wear liners, hardfaced pipe assemblies, high-alloy flux-cored wires, and custom-designed automatic surfacing welding equipment. Runxing’s advanced manufacturing facility integrates multi-head automated cladding systems that ensure uniform deposition control, tight thickness tolerances, and minimal dilution zones.

Learn More >The hardfacing industry is moving towards complete process automation and precise control of metallurgical dilution. When depositing high-chromium alloys onto mild steel substrates, controlling the dilution rate—the ratio of base metal melted into the overlay—is critical. Excessive dilution reduces the carbon and chromium content of the deposit, compromising wear resistance. Our automatic surfacing systems use digital control units, closed-loop voltage regulators, and precision oscillators to maintain low penetration of the base steel, ensuring that the first layer achieves over 50% primary carbide concentration.
Our research and development pipeline focuses on introducing multi-element complex carbides. By adding small amounts of strong carbide-forming elements such as Niobium, Titanium, Tungsten, and Boron, we refine the microstructure and promote the growth of secondary micro-carbides. These complex alloys exhibit higher toughness and heat resistance than standard chromium iron systems. This technology enables the production of overlay plates that can operate in hot sinter plants and waste-to-energy boilers without cracking or premature wear.
In addition, our automatic surfacing equipment features a multi-axis CNC path generator. Operators can program complex weld paths via a 10.2-inch touch interface, accommodating varying swing widths, travel speeds, and overlapping ratios. The system supports multi-wire configurations, enabling high deposition rates of up to 12 kg/h per arc. This high throughput reduces the cost of large-scale wear liner fabrication, while providing consistent quality across production runs.
To meet the demands of major industrial groups in Europe, the Americas, and Central Asia, all Runxing hardfacing products undergo systematic testing. Our wear plates are manufactured to comply with DIN 8555 specifications. Hardfacing deposits are tested using ASTM G65 dry sand rubber wheel abrasion tests to verify material performance. Additionally, regular metallographic examinations are conducted to verify primary carbide distribution, volume fraction, and the absence of interfacial voids between the cladding layer and the base plate.
