See Chemical Analysis >Founded in 2010 and situated in Tangshan, Hebei Province—the heartland of China's heavy industrial metallurgy—Tangshan Runxing Machinery Co., Ltd. is a leading professional manufacturer dedicated to the research, development, production, and on-site construction of premium hardfacing wear-resistant metal products.
Our core manufacturing capabilities cover an extensive range of industrial wear solutions: chromium carbide overlay (CCO) wear plates, custom processed wear liners, wear-resistant pipes and pipe fittings, hardfacing flux-cored welding wires, automatic hardfacing welding machines, and on-site roll surfacing repair services. Driven by the philosophy of "Integrity, Superior Quality, Innovation & Sustainable Development", we own mature, advanced metal surface hardfacing technology.
To ensure absolute efficiency, transparency, and reliability in international commerce, all export business is fully authorized and handled by Hebei Yuwan International Trade Co., Ltd. This strategic separation allows our trade company to handle all compliance, customs clearance, shipping logistics, and payment collection, while the factory remains focused on manufacturing excellence and technical R&D.
By integrating our deep metallurgical knowledge with top-tier partners, such as maintaining a qualified agency for VAUIID (VAUTID) in Germany, we guarantee our wear products stand up to the most brutal operations globally.
In modern heavy industries—ranging from cement plants in Western Europe to gold mines in South America—equipment downtime due to mechanical wear represents a multi-billion dollar challenge. Dry sliding abrasion, high stress grinding, and particle impact degrade machinery surface integrity. Automated welding machines and premium hardfacing materials (such as chromium carbide overlay composite plates) have evolved from simple maintenance tools to critical components of plant lifecycle management.
Our standard wear-resistant steel plate cladding features structural steel backing plates fused with high-alloy wear surfaces. Under the DIN 8555 code system, our alloys deliver outstanding microstructural stability. The cladding layer contains high concentrations of primary chromium carbides ($Cr_7C_3$) suspended in a tough eutectic matrix. The microscopic hardness of these chromium carbides exceeds 1500 HV, which prevents sharp mineral particles from cutting into the base metal, extending operations by 5x to 10x compared to carbon steel.
Operating out of Tangshan, Hebei Province, Tangshan Runxing Machinery benefits from direct proximity to the world's most robust steel logistics, raw metal resources, and specialized engineering talents. This concentration allows us to achieve production efficiencies that other global competitors cannot replicate. Through vertical integration—from wire formulation to customized profile cutting and state-of-the-art automatic cladding systems—we reduce raw material lead times and pass significant cost savings to our global clients.
Manual welding cannot guarantee the strict deposition rate, uniform thermal profile, and flatness required for large-scale industrial wear protection. The RX® Surfacing equipment incorporates modern CNC parameters via a 10.2-inch intuitive touch interface. Key innovations include:
The key issue for any cement plant lies in the availability of critical equipment. The key to equipment availability is wear resistance, and the performance of wear-resistant products determines the operating time of critical equipment. Applications include separator vanes, vertical roller mill liners, and feed chutes.

From April 24th to April 27th, Tangshan Runxing Machinery Co., Ltd. participated in EXPOMIN 2023, the world's second largest professional mining exhibition for the first time, with exhibits covering products from all fields of mining and wear linings, cementing relationships in South America.
Read Article >A1: Our wear plates are composite plates composed of a structural mild steel backing plate (such as Q235 or Q345) and a hardfaced layer containing high-chromium alloy. This combination aligns with the DIN 8555 standard, which guarantees the hard wear layer resists severe mineral grinding and particle abrasion while the structural backing accommodates impacts and weld installation.
A2: A four-gun automated hardfacing system provides balanced heat input across the steel sheet. The computerized controller precisely regulates parameters such as current, voltage, swing speed, and travel velocity. This consistency eliminates manual operator error, avoids high localized warping, ensures uniform deposit thickness, and yields consistent hardness across the entire plate surface.
A3: Tangshan Runxing Machinery is dedicated to research, metallurgical testing, and factory floor manufacturing. To maximize trade compliance, all export formalities, shipping logistics, customs declarations, and payment collections are handled by Hebei Yuwan International Trade Co., Ltd. This division of labor allows each organization to focus on their respective competencies, simplifying procurement for our international buyers.
A4: Being a qualified agent of German VAUTID materials for six consecutive years means we maintain strict compliance with global premium metallurgical standards. We integrate VAUTID alloy formulations for wear-resistant products that require certified high-stress wear resistance and chemical stability in extreme thermal or corrosive industrial setups.
A5: Yes. Although the hard cladding layer is extremely hard (averaging 58-62 HRC), the structural steel base allows for plasma arc cutting, back-gouging, and rolling. We regularly supply custom processed liners, hopper linings, and pre-formed wear-resistant pipes with high-accuracy CAD tolerances based on engineering designs from cement or steel mill facilities.
A6: In standard cement separators or mining chutes, substituting conventional carbon steel with our CCO plates increases operational life by 5 to 10 times. In high-stress grinding roll mill applications, our specialized wear overlays dramatically reduce maintenance downtime, yielding significant lifecycle cost savings.
A7: Fine stress-relief micro-cracks are a natural physical trait of high-alloy hardfaced overlays. These cracks, which run perpendicular to the weld bead direction, relieve structural tension from the welding process and do not compromise the integrity of the carbon steel backing. The composite remains stable under typical working pressures.
A8: Yes, our plant produces custom-engineered flux-cored and self-shielded hardfacing wire formulations. Customers can request specific chromium-to-carbon ratios, or add molybdenum, niobium, and boron elements to meet specific wear, heat, or impact conditions.
Advanced automatic surfacing equipment featuring a 10.2-inch touch screen control interface, 4 simultaneous welding heads, uniform speed swing oscillation, and multi-wire capability for high efficiency wear plate fabrication.
