Operating in sub-zero Arctic environments poses unique metallurgical challenges: typical base metals become brittle under extreme cold, and thermal shocks accelerate surface micro-cracking.
Industrial wear components in Finland require specialized wear solutions. Standard quenched and tempered steels often experience high rate abrasion wear, causing frequent maintenance shutdowns. The application of Runxing's Chromium Carbide Overlay (CCO) plates and high-chromium welding wires ensures that equipment parts—such as conveyor chutes, hoppers, screw flights, and pulverizer assemblies—maintain maximum operational availability. The controlled stress-relief micro-cracks in our overlay plates relieve internal welding tensions, preventing delamination when exposed to thermal cycling between -40°C and normal operating temperatures.
In addition, Finland's strict environmental regulations demand energy-efficient operations. High-quality hardfacing reduces machinery friction, directly lowering energy consumption and extending component service life. This minimizes total carbon emissions associated with part fabrication and maintenance cycles.
Tangshan Runxing Machinery Co., Ltd., established in Hebei Province in 2010, specializes in the research, development, and production of chromium carbide overlay wear plates, high-hardness flux-cored welding wires, and custom wear components. Over more than a decade, we have established a robust metallurgical research foundation, incorporating high-quality German VAUTID alloy systems to maintain strict quality standards.
Our export processes are managed by Hebei Yuwan International Trade Co., Ltd., ensuring compliance with European Union documentation standards, customs clearance, and global shipping logistics. Our factory operates automated CNC weld overlay stations and advanced inspection labs to verify weld bead chemistry, micro-hardness profiles, and dilution control.
By controlling dilution during the surfacing process, our CCO plates achieve a consistent volume of primary chromium carbides ($Cr_7C_3$) within the iron-carbide matrix. This results in wear plates with a surface hardness ranging from 58 to 62 HRC. This high concentration of primary carbides provides reliable resistance against severe sliding abrasion in mining, power generation, and cement plants.
The wear resistance of Runxing hardfacing consumables relies on the formation of primary M7C3 carbides during solidification. Unlike standard steel plates that rely on mechanical heat treatments, our weld overlays form a metallurgical bond with the base plate. Under carbon-chromium ratio control, the microstructure exhibits hexagonal carbides perpendicular to the wear direction, maximizing resistance against abrasive particulate flow.

|---|---|---|---|---|
| RX-wp 7600 | Cr7C3 Hexagonal Crystals | 58 - 62 | S235JR / S355J2G3 | Heavy Mineral Chutes, Hoppers, Sinter Ducts |
| RX-FCW 100S | Hypereutectic Alloy | 57 - 61 | Mild Steel / Low Carbon Alloys | Open-Arc Hardfacing of Mining Buckets & Screws |
| RX-PTTA-N | Complex Carbides (Ni-W-Cr) | 60 - 65 | Cast Steels / Manganese Steel | Severe Scraping Edge, High-Temperature Slag Liners |

A: Our plates are designed to withstand thermal expansion stresses under sub-zero conditions. The pre-existing micro-cracking pattern relief system in the chromium carbide overlay prevents propagation of cracks into the base plate, preserving weld integrity down to -45°C.
A: Self-shielded flux-cored wires (like our RX-FCW series) do not require external shielding gas, making them suitable for onsite maintenance in windy conditions. Gas-shielded wires typically produce less fume and slag, which is ideal for indoor workshop applications.
A: Our products are manufactured to meet DIN 8555 specifications and relevant EN ISO standards. Chemical compositions are checked via spectrometer testing to confirm chromium and carbon ranges.
A: All international orders and export documentation are processed by Hebei Yuwan International Trade Co., Ltd., which manages shipping coordination, customs clearance, and import compliance requirements.
A: Yes. The base plates (typically S235 or S355 grade carbon steel) can be welded using conventional low-hydrogen electrodes or gas metal arc welding (GMAW) processes.
A: Depending on the complexity and dimensions of the drawings, production takes approximately 15 to 25 days. Shipping times to Finnish ports are coordinated to optimize schedule reliability.
A: Yes. We offer rebuild services using automated surfacing systems. Rollers can be rebuilt either onsite or at our regional servicing partners using high-chromium flux-cored wire.
A: Quenched and tempered steel provides high impact resistance but can wear quickly in sliding abrasion applications. CCO wear plates contain primary chromium carbides ($Cr_7C_3$) that offer superior wear life in high-abrasion environments.
