Read PTTA ProcessProcuring raw materials for surface hardfacing requires strict adherence to quality parameters. Global supply chains struggle to maintain consistency in grain size distribution for welding powders and consistency of the internal flux filling ratio inside high-chromium wires. Tangshan Runxing Machinery Co., Ltd. addresses this gap by utilizing high-purity raw minerals, providing continuous chemical composition traceability, and standardizing export routing through Hebei Yuwan International Trade Co., Ltd.
Our global clients seek more than just standard components; they demand comprehensive solutions. By integrating wear plates, custom fabricated liners, and roller cladding services, we provide a unified procurement ecosystem. This reduces assembly failures, minimizes localized stress cracking, and matches target components with the exact alloy composition required to defend against specific wear profiles.
Discover the chemistry behind our high-durability wear products. Runxing employs advanced crystallization controls to optimize chromium carbide grain structures.

Founded in 2010 in Tangshan, Hebei Province—the heartland of China's heavy industrial metal processing sector—Tangshan Runxing Machinery Co., Ltd. has established itself as an innovative force in hardfacing wear-resistant metal technology. Our company integrates material development, precision machining, and specialized repair services under one roof.
We manufacture chromium carbide overlay (CCO) wear plates, custom wear liners, hardfacing flux-cored welding wires, and automatic welding machinery. Additionally, our experienced service team provides on-site roller surfacing repairs for steel mill and cement grinding systems globally.
To streamline international supply chains, all export processes are managed by Hebei Yuwan International Trade Co., Ltd. This dedicated entity ensures seamless handling of international trade compliance, customs clearance, shipping logistics, and secure cross-border payment collections.
Critical raw material processing machinery must remain operational to prevent production bottlenecks. Our chromium-rich hardfacing overlays protect feed hoppers, separator guide vanes, and vertical roller mills from abrasive raw meal feed.

Mine operators require durable wear plates to handle abrasive ores. Our CCO wear plates and self-shielded flux-cored wires are ideal for high-stress grinding abrasion in shovel buckets, dump truck beds, and transfer chutes.
See Mining Solutions
The combination of thermal load, heavy impact, and slag erosion makes wear protection crucial in steel plants. We provide customized overlay materials for guide plates, coke screening decks, and continuous caster rolls.

Visit PortalChromium Carbide Overlay (CCO) plates are composite materials containing hypereutectic chromium carbides (M7C3) deposited onto a tough structural backing plate. Standard hardened steel plates (like Q&T AR400/500) rely on martensitic hardness, which can soften under frictional heat and impact. CCO plates provide superior wear resistance under severe sliding abrasion and maintain performance at elevated temperatures, often lasting 4 to 6 times longer than standard hardened steel.
Self-shielded flux-cored wires contain internal fluxing agents that generate their own shielding gas during the welding arc. This eliminates the need for high-pressure external gas tanks, which are difficult to manage in windy outdoor environments, mining sites, or elevated cement plant processing structures.
Hebei Yuwan International Trade Co., Ltd. is the authorized export service partner for Tangshan Runxing Machinery Co., Ltd. They handle all international commercial operations, including customs declaration, shipping logistics, export documentation, and payment collection. This allows our factory teams to focus on manufacturing and quality control, while providing our international clients with efficient trade services.
Yes. While the overlay side is hard and resistant to forming, the structural steel backing (mild steel like Q235B or ASTM A36) can be welded using standard methods. Plates can be cold-formed or rolled into cylinders or cones within specified radius limits (typically with the hard overlay on the inside). We can also cut and drill plates to match CAD drawing specifications using plasma arc systems.
Each batch of our wear plates undergoes strict quality checks, including ultrasonic testing for bond integrity between the backing steel and overlay, Rockwell hardness testing (HRC) across multiple surface points, and microstructure analysis under optical microscopes to verify carbide density and distribution. We also conduct wear loss tests matching ASTM G65 standards.
