Tangshan Runxing Machinery Co., Ltd., founded in 2010, is a professional manufacturer located in Tangshan, Hebei Province—the heartland of China's heavy industrial and metallurgical clusters. We focus on the R&D, precision manufacturing, and on-site engineering services of hardfacing wear-resistant metal products.
Our core manufacturing capabilities cover chromium carbide overlay (CCO) wear plates, customized wear liners, wear-resistant pipes, hardfacing flux-cored welding wires, automatic surfacing equipment, and roll reclamation services. Guided by the business philosophy of "Integrity, Superior Quality, Innovation & Sustainable Development", we continuously drive innovation in industrial wear protection.
To ensure seamless global transactions, all export initiatives are fully handled by Hebei Yuwan International Trade Co., Ltd. This strategic partnership enables our factory to focus entirely on metallurgical quality control and engineering R&D while providing international buyers with streamlined customs clearance, shipping, and payment logistics.
The global heavy machinery sector is undergoing a massive transformation under the concept of "OEM Learn Welding". Rather than relying on traditional manual repair methods, modern heavy industries are embracing automated surfacing metallurgy to extend structural life. In tribology, wear protection represents a major opportunity for cost reduction. By learning the mechanics of dilution, fusion, and heat input, OEMs can customize hardfacing structures that withstand extreme abrasion, heavy impact, and temperature stresses.
"The true measure of a hardfacing overlay lies in its microstructural integrity. The primary chromium carbides (M7C3) must be evenly dispersed within a tough, stable austenitic matrix to achieve optimal wear protection under high-stress conditions."
Procurement departments in mining, cement, steel, and power generation are shifting from buying standard plates to procuring performance-defined, custom-engineered composite materials. Key enterprise requirements include:
Runxing Machinery leverages Tangshan's local metallurgical supply chain to offer unmatched efficiency and quality control. By using automated robotic cladding stations and intelligent flux-cored wire production lines, we reduce energy consumption while maintaining uniform hardness profiles. Our integration of advanced control systems allows us to dynamically adjust arc parameters, ensuring every square meter of overlay meets rigorous international standards.

Our debut at EXPOMIN, the world's second-largest professional mining exhibition, allowed Runxing to showcase our bimetallic wear liners and overlay solutions directly to South American mine operators, expanding our distribution channels in Chile, Peru, and Brazil.
Read More >Traditional wear-resistant steel (such as quenched and tempered steel) relies on overall hardness to resist wear. Once the hardened surface wears down, the abrasion rate increases. Chromium Carbide Overlay (CCO) plates are composite materials containing primary chromium carbides (M7C3) with microhardness values reaching 1500–2000 HV. They are deposited onto a structural backing plate, providing a wear-resistant surface while maintaining structural toughness and weldability.
We employ a strict quality assurance protocol that monitors every step of production. This includes spectroscopic analysis of raw materials, ultrasonic inspection of the bimetallic interface to ensure zero delamination, microscopic verification of the primary carbide distribution, and hardness testing across the wear surface. All manufacturing aligns with DIN 8555 and ASTM G65 standards.
This partnership allows us to optimize our operations. Runxing focuses on production quality and technological R&D in our Tangshan facility. Hebei Yuwan International Trade Co., Ltd. handles international logistics, customs clearance, shipping documentation, and payment verification, ensuring professional and reliable service for our global clients.
Yes. We specialize in customizing dimensions, chemical compositions, and overlay thicknesses. We can modify alloy formulas to balance impact resistance, temperature tolerance, and abrasion protection. Custom cutting, rolling, and mounting holes can also be completed before shipping.
Self-shielded flux-cored wires do not require external shielding gas, making them suitable for outdoor and high-wind environments like mines and cement silos. They simplify field welding equipment setups, permit deeper joint penetration, and allow for high deposition rates in difficult positions.
In addition to maintaining ISO quality management systems, we collaborate with Tangshan University's Metal Materials and Forming Technology teams. This relationship supports ongoing research into metallurgy, weld overlay optimization, and heat-affected zones. We have also served as a qualified agent for Germany's VAUTID brand for six consecutive years.
