Kazakhstan is the dominant economic powerhouse of Central Asia, boasting massive reserves of mineral resources. From the coal basins of Karaganda and Ekibastuz to the copper-rich ores processed by Kazakhmys and Kazzinc, the country's extraction machinery operates under some of the most unforgiving environments globally. Mining equipment, chute chutes, vibrating screens, and hopper systems are constantly subjected to severe sliding abrasion and impact forces.
Moreover, the continental climate of Kazakhstan—characterized by extreme temperature swings from -40°C in winter to +40°C in summer—demands materials that maintain structural integrity and fracture toughness under thermal shock. Standard carbon steels and traditional Quenched and Tempered (Q&T) plates often fail prematurely. This leads to costly unscheduled maintenance stops. Chromium Carbide Overlay (CCO) bimetallic plates represent the gold standard in modern metallurgy, offering a highly wear-resistant layer fused to a ductile, structural backing plate.
The superior performance of bimetallic plates lies in their microstructure. Runxing's wear plates are produced via a specialized open-arc welding process that overlays a hypereutectic chromium alloy onto a structural steel base (typically Q235B or Q355B). This hardfacing layer exhibits a dense dispersion of primary M7C3 chromium carbides (with microhardness reaching up to 1500 HV) embedded in a tough, austenitic matrix.
Under DIN 8555 standards, our overlays are precisely engineered to balance high abrasion resistance and moderate impact toughness. The base plate provides excellent weldability and structural support, allowing the complex liner assembly to be welded directly onto machine frames, avoiding standard mechanical fastening failures.
For industrial buyers in Kazakhstan, purchasing foreign heavy machinery components requires absolute reliability. Tangshan Runxing Machinery Co., Ltd., founded in 2010, operates a state-of-the-art facility in Tangshan, China. To ensure frictionless cross-border transactions, all export businesses are fully authorized and managed by **Hebei Yuwan International Trade Co., Ltd.**
This strategic configuration allows Runxing's factory to focus entirely on advanced metallurgical research and manufacturing quality. Meanwhile, Hebei Yuwan handles the end-to-end logistics, customs clearance at major land ports like Alashankou/Dostyk and Khorgos, and manages all compliance documentation. This ensures seamless DDP/DAP deliveries straight to major industrial hubs in Ust-Kamenogorsk, Karaganda, and Shymkent.

To deliver industrial grade solutions, Runxing adheres to rigorous QA/QC procedures. Our plates are tested using ASTM G65 dry sand/rubber wheel abrasion tests to guarantee wear rates stay well below industry averages. We strictly control dilution rates from the base plate to maintain a rich chromium carbide matrix.
As operating parameters in deep underground mines become more aggressive, traditional chromium-iron alloys face thermodynamic limitations. Our engineering roadmap includes the addition of transition metals such as Niobium (Nb), Boron (B), Titanium (Ti), and Tungsten (W). This creates complex carbide systems that can survive service temperatures exceeding 650°C and severe abrasive grinding.
