Across global heavy industries—including steel manufacturing, open-pit mining, coal-fired power plants, and maritime cargo handling—mechanical components constantly battle severe surface degradation. High-stress grinding, sliding friction, structural erosion, and thermal oxidation are critical drivers of equipment failure and operational downtime. In response to these challenges, Plasma Surface Treatment and Plasma Transferred Arc (PTA) cladding have emerged as standard metallurgical processes to prolong service life and improve cost efficiency.
Traditional hardfacing, while cost-effective, often struggles with high dilution rates, where the substrate metal blends into the protective alloy coating, degrading its hardness. In contrast, PTA cladding utilizes a highly concentrated plasma arc as a heat source to melt both the substrate surface and the alloy feeding materials (such as chromium carbide powders or flux-cored wires). This results in a dense, metallurgically bonded coating with a dilution rate often below 5%. The resulting material exhibits superior abrasion, impact, and corrosion resistance, suitable for extreme operating temperatures.
Founded in 2010 in Tangshan, Hebei Province—the core of China's heavy industrial and metallurgic manufacturing corridor—Tangshan Runxing Machinery Co., Ltd. has established itself as an R&D-led manufacturer of hardfacing wear-resistant metal products. Runxing focuses on custom product development, on-site engineering, and advanced surface modification technologies.
Our core catalog includes Chromium Carbide Overlay (CCO) wear plates, bimetallic composite wear liners, wear-resistant pipes and fittings, hardfacing flux-cored welding wires, and automated surfacing machinery. By positioning our primary manufacturing plant in Hebei, we leverage high-grade steel supplies and metallurgical research networks. All international trade, customs clearance, and global logistics are facilitated through Hebei Yuwan International Trade Co., Ltd., ensuring compliance and smooth shipping workflows.
The performance of hardfacing wear plates depends on the chemistry of the deposited layer. Runxing’s proprietary wear plate series, including the RX®wp 7600 (conforming to the DIN 8555 standard), features a structural steel backing bonded with a high-chromium overlay.
High concentration of chromium carbides ($Cr_{7}C_{3}$) embedded within a tough, impact-resistant austenitic matrix.
Primary hexagonal carbides grow perpendicularly to the base plate, preventing crack propagation and micro-spalling.
Microprocessor-controlled arc oscillation ensures homogeneous bead deposition and minimal thermal stress distortion.
The hardfacing deposit typically measures between 55 to 62 HRC (Rockwell Hardness). The base plate—commonly Q235B or Q345B structural steel—absorbs vibration and impact, while the outer overlay resists abrasive wear. This bimetallic design reduces structural weight while maintaining high mechanical strength.
Runxing designs custom wear-resistant solutions tailored to the operational demands of diverse heavy industries.
Clinker chutes, hopper liners, and raw material mill plates require abrasion protection to ensure uninterrupted plant operation.

Operating from Tangshan, Hebei, Runxing integrates raw materials sourcing, custom alloy blending, wire fabrication, and automated plate surfacing into a single production workflow. This vertical integration allows control over the entire quality loop and shields production schedules from market volatility.
Proximity to major steel producers ensures direct access to structural backing steels (Q235B, Q345B) and high-carbon ferrochrome raw materials.
In-house flux-cored wire manufacturing lines allow rapid tuning of alloy chemistry to meet specific wear resistance parameters.
Dedicated export management through Hebei Yuwan International Trade Co., Ltd. handles customs documentation, payments, and international logistics.
This structured operation allows Runxing to maintain short lead times and stable pricing, even during raw material price fluctuations. Global buyers in Russia, Central Asia, and Africa benefit from clear pricing structures and predictable delivery schedules.
Runxing maintains technical credibility through ongoing R&D investments and partnerships with academic institutions. In 2023, the leadership of Tangshan University, including Dean Yuan Shaoqiang and Professor Yang Yuehui (Team Leader of Metal Materials and Forming Technology), conducted a collaborative research review at our facility. Together with Runxing’s General Manager Li Xiuhua and Vice General Manager Cui Jianying, the group established frameworks to commercialize new metallurgical formulations for wear mitigation.
This combination of academic R&D and industrial partnerships ensures that Runxing's products meet the quality, tolerances, and metallurgical properties required by international standards.

Read More >The hardfacing industry is shifting toward higher degrees of automation and tailored microstructures. Runxing’s engineering roadmap focuses on three main developments:
Modern surfacing requires uniform weld thickness and thermal management to minimize stress. Our automated surfacing machines utilize multi-axis CNC controllers and 10.2-inch touch interfaces to dynamically adjust the welding swing path, current intensity, and powder feed rates. This reduces defects like porosity and uneven dilution, ensuring uniform overlay performance.
To address combined wear environments, such as simultaneous high-stress impact and acid corrosion, Runxing is developing multi-alloy coatings. By adding transition metals like niobium (Nb), vanadium (V), and tungsten (W) to the chromium carbide matrix, the resulting overlay forms complex carbides that resist abrasive wear at temperatures up to 800°C.
Rather than replacing worn components, remanufacturing through PTA cladding offers a more sustainable alternative. For example, rebuilding worn industrial grinding rolls and continuous casting table rollers reduces raw material consumption by up to 70% compared to manufacturing new replacements, supporting industrial decarburization efforts.
Common questions answered by our engineering and metallurgical support team.
A1: Plasma Transferred Arc (PTA) cladding uses a focused plasma arc to deliver concentrated heat energy, resulting in a narrow heat-affected zone (HAZ) and low base-metal dilution (under 5%). Traditional open-arc CCO welding operates at higher heat inputs, leading to higher dilution (15-25%), which can lower the concentration of chromium carbides in the first deposited layer.
A2: Yes, we provide full OEM/ODM fabrication services. Using client CAD drawings, we perform cutting, bending, rolling, and bolt-hole insertion on our wear plates to supply ready-to-install liners for chutes, hoppers, or pipes.
A3: It allows us to combine VAUTID’s alloy formulations with our local manufacturing capacity. This enables us to produce high-grade overlay plates and wire consumables locally, offering European technical standards at competitive pricing.
A4: These cracks are stress-relief cracks that form naturally during cooling due to thermal contraction differences between the hard chromium carbide overlay and the structural steel backing. They do not affect the plate's wear resistance and prevent the backing plate from warping.
A5: All export transactions, customs documentation, shipping arrangements, and international payment processing are managed by our authorized partner, Hebei Yuwan International Trade Co., Ltd., allowing our factory to focus on manufacturing quality.
