Technical SpecAs Pakistan advances its infrastructure networks, power plants, and industrial processing hubs under the **China-Pakistan Economic Corridor (CPEC)**, the operational reliability of production machinery becomes crucial. Raw material handling systems in the **Thar Coalfield**, cement complexes in Punjab and Khyber Pakhtunkhwa (KPK), and steel mills in Karachi encounter severe degradation challenges.
Traditional carbon steels (like Q235, Q345) and even hardened manganese steels fail prematurely when subjected to continuous sliding abrasion. The high-stress scratching forces in vertical roller mills (VRM), coal chutes, sinter hoppers, and port bulk hoppers require materials with a high concentration of primary chromium carbides (M7C3).
Tangshan Runxing Machinery Co., Ltd. supplies high-hardness **Chromium Carbide Overlay (CCO) plates** and customized liner plates to Pakistan’s industrial hubs. These plates feature a structural steel backing plate for weldability and structural integrity, paired with a wear-resistant overlay alloy cladding deposited via advanced open-arc or submerged arc cladding technology.
Globally, heavy industries are moving away from traditional thick carbon plates to thinner, lighter bimetallic wear composite plates. This transition reduces structural load while providing longer service life.
Optimized wear liner configurations developed specifically for the operational demands of Pakistan’s primary industrial sectors.
Pakistan’s cement producers (located in the Salt Range, Punjab, and Karachi clusters) handle massive volumes of limestone, clay, and gypsum. Hardfacing overlay plates are installed inside:
Thar Coal reserves and Balochistan’s copper-gold extractions (Reko Diq & Saindak) subject excavation machinery to continuous abrasive abrasion. Bimetallic liners are utilized in:
Coal-fired power plants in Sahiwal, Port Qasim, and Hub burn pulverized coal. Handling high-velocity abrasive coal dust requires erosion-resistant ductings:
In domestic steel melting units and billet plants across Lahore, Karachi, and Taxila, materials move through charging systems at extreme temperatures. Advanced wear plates protect:
Bulk terminals at Port Qasim and Karachi Port manage fertilizer, coal, clinker, and wheat imports. Continuous unloading requires wear-resistant flow structures:
We implement high-tech manufacturing parameters. Controlling chemistry, cooling gradients, and welding parameters ensures every wear plate delivered to Pakistan achieves optimal hardness.
*All wear plate chemical composition analysis and hardness testing results are verified via third-party metallurgy lab reports and match ASTM G65 abrasion test standards.

Common inquiries from engineers regarding performance, installation, and fabrication of chromium carbide overlay plates.
The overlay microstructures contain a high volume of primary M7C3 chromium carbides embedded in an austenitic matrix. During the weld deposition process, chromium and carbon precipitate into hexagonal chromium carbide crystals (with hardness exceeding 1500 HV). This structure is supported by the tougher austenitic matrix, which absorbs impacts while resisting abrasive particle scratching.
Yes. The structural backing plate (typically standard carbon steel Q235B or ASTM A36) allows for conventional fabrication. The plate can be cut from the backing side using plasma arc cutting. It is joined to structural components via plug welding, stud welding, or countersunk bolting. The hard overlay face cannot be machined or cut with gas; all shaping must be performed from the backing plate side or via plasma/abrasive waterjet cutting.
These hairline cracks are called stress-relief cracks. They form naturally during the high-temperature weld deposition process. As the cladding alloy cools, the difference in thermal contraction rates between the backing steel and the chromium carbide layer creates stress. The relief cracks occur perpendicular to the welding bead, ending at the boundary of the backing plate. These cracks do not reduce wear performance or cause delamination.
We run CNC-controlled automated multi-gun surfacing systems that control welding speed, voltage, and oscillating widths. This ensures a consistent carbide deposit depth. Each manufacturing batch undergoes thickness verification via ultrasonic testing, surface hardness inspections, and microstructure audits. All export orders are certified and shipped via Hebei Yuwan International Trade Co., Ltd., accompanied by full mill test certificates (MTCs).
