Explore SpecificationsBarcelona and the wider Catalonia region represent Spain's most dynamic industrial engine. With the Port of Barcelona serving as a crucial maritime gateway for solid minerals, grain, cement clinker, and steel, heavy infrastructure is constantly exposed to extreme mechanical abrasion and sliding wear. Local machinery operators in logistics hubs, quarries, recycling plants, and casting foundries face millions of Euros in downtime and maintenance costs annually due to component wear.
The transition toward localized industrial circular economies in Catalonia requires high-performance wear plates that extend the lifecycle of machinery. The integration of Chromium Carbide Overlay (CCO) plates has become the modern baseline for operations along the Llobregat river manufacturing corridor, where cement factories, steelworks, and chemical processing facilities demand DIN-tested wear-resistant materials.
Industrial statistics confirm that substituting structural carbon steels with premium bimetallic wear liners inside Port bulk terminals can increase machinery operating spans by up to 800%, radically lowering the cost-per-ton of processed materials.
Furthermore, local Catalan repair shops require highly weldable flux-cored hardfacing wires that can be applied in open-air environments (such as dockside crane repairs or sorting yard chutes) without requiring complex shielding gas arrays. This is where Tangshan Runxing’s specialized self-shielded wire systems yield substantial operational benefits.
Tangshan Runxing Machinery’s premium bimetallic steel plates (such as the RX®wp 7600) utilize a low-carbon structural backing plate combined with an extremely hard, alloy-saturated cladding layer. The chemistry of this cladding layer is designed with a high concentration of Chromium and Carbon. Under controlled cooling rates during the surfacing process, this chemistry forms primary hexagonal M7C3 chromium carbides dispersed within a tough, hard eutectic matrix.
The key to superior performance lies in the carbide volume fraction and distribution. Our plates feature a carbide volume fraction exceeding 35%, with macro-hardness consistently reaching 58 to 62 HRC. While standard steel grades rely on heat-treating (quenching and tempering) which can soften under frictional heat, Runxing’s bimetallic plates maintain structural integrity at elevated temperatures up to 600°C.
| Property / Characteristic | Runxing CCO Wear Plate (RX®wp 7600) | Standard Quenched & Tempered (e.g., Hardox 450/500) | Cast High Manganese Steel |
|---|---|---|---|
| Base Material Matrix | Carbon Steel Base (Q235B/Q345B) + Hypereutectic Cr Carbide | Homogeneous alloy steel through-hardened | Single-piece manganese cast alloy |
| Typical Surface Hardness | 58 - 62 HRC (650 - 750 HV) | 45 - 50 HRC (450 - 520 HV) | 200 HB (work-hardens to ~500 HB) |
| Microstructure Advantage | High concentration of primary M7C3 hexagonal carbides | Tempered Martensite (low relative carbide fraction) | Austenitic structure (requires high impact to harden) |
| Abrasion Resistance (ASTM G65) | Extremely High (typical weight loss < 0.15g) | Moderate (prone to rapid wear under mineral sliding) | Low under sliding wear; high under heavy impact |
| Welding & Fabricability | Easy welding on base steel, plug welding capability | Requires precise preheating; prone to heat-softened zones | Complex welding parameters required |
Choosing a Chinese supplier for industrial wear materials often hinges on quality assurance and logistical efficiency. Tangshan Runxing Machinery, founded in 2010 in Tangshan, Hebei Province (the industrial steel heartland of China), has established a world-class manufacturing facility utilizing advanced, self-developed multi-head automatic hardfacing cladding equipment.
Our production scale, local alloy sourcing, and R&D collaboration with Tangshan University ensure consistent raw material pricing and metallurgical superiority. Key advantages include:
High-vibration and severe sliding wear conditions require reliable wear-resistant cladding. Runxing CCO plates provide extended operational windows for chutes, cyclone separators, and vertical cement grinding roller surfaces.

Protecting equipment against sintering raw materials, coke, and high temperatures. Runxing's high-temperature resistant chromium carbide overlays perform reliably in demanding blast furnace environments.
Request Steel Case Studies
Coal mill dust systems, exhauster fan blades, and coal pulverizer mill liners demand extreme abrasion resistance combined with dynamically balanced profiles. Runxing delivers custom fabricated liners to meet these tight tolerances.

For high-abrasion applications with low-impact profiles where steel weldments are not optimal. Sintered high-purity alumina ceramics provide an alternative to CCO plates in specific chute configurations.
Explore Ceramic AlternativesGenerally, under pure sliding abrasion (such as fine particle chute flow or cement clinker handling), a high-quality Chromium Carbide Overlay (CCO) plate will outlast standard AR500 quenched and tempered steels by 4 to 8 times. Under severe impact, bimetallic plates require a backing plate to absorb the energy, but they retain their outer abrasion resistance significantly longer.
All international shipments from Tangshan Runxing are fully cleared and managed by Hebei Yuwan International Trade Co., Ltd. They handle export declarations, certificate of origin paperwork, sea freight bookings directly to the Port of Barcelona, and can arrange DDP/CIF delivery terms to coordinate smoothly with Spanish customs agents.
Yes, because the base plate is typically composed of structural carbon steel (like Q235B or Q345B), these plates can be rolled or bent to form inner or outer radii (to line pipes or circular chutes). Cutting must be performed using plasma cutting machinery, waterjet, or carbon arc gouging from the back side (base metal side) to avoid contaminating the cut path with chromium carbide particles.
Our overlay compositions correspond to DIN 8555 standards (specifically classes like MSG 10-GF-60-G or MF 10-GF-60-GR), which represent gas-shielded or open-arc flux-cored configurations designed for extreme mineral abrasion up to 600°C.
