Runxing's hardfacing technologies maximize M7C3 primary carbides (typically 1500 HV hardness) to counter material loss and operational degradation.
The global hardfacing consumables market is shifting rapidly from traditional solid wires to advanced flux-cored wires (FCW). In automated cladding, flux-cored wires exhibit higher deposition rates, lower thermal distortion, and a highly customizable chemical formulation. Manufacturers can incorporate alloying elements—such as chromium, niobium, titanium, and carbon—directly into the core, allowing precise adjustments for specific working environments. Additionally, the development of self-shielded flux-cored wire has revolutionized field maintenance by removing the requirement of external shielding gases, preventing porosity caused by windy environments in outdoor applications.
Global procurement teams in heavy industry are seeking total ownership cost reduction. Sourcing from experienced ODM/OEM factories offers significant advantages, including custom chemical compositions, tailored plate dimensions, and automated cladding machinery setups. Enterprise clients prioritize reliable metallurgical bonding, minimal base metal dilution, and consistency in crack distribution patterns (which are vital for releasing stress and preventing propagation into the base structural plate). Standardized chemical composition controls prevent premature wear, assuring longer lifecycle predictions for chutes, hoppers, and rollers.

Stress-relief cracking is a normal physical property of high-quality CCO wear plates. During the weld deposition process, high temperatures trigger thermal shrinkage between the weld overlay and the structural steel backing. The formation of cracks across the weld bead relieves internal stress, preventing warping, deformation, and delamination of the plate. These cracks exist solely in the overlay layer and do not propagate into the base steel plate.
Gas-shielded wire relies on an external gas envelope (commonly CO2 or Argon/CO2 mixtures) to protect the molten pool from atmospheric oxygen and nitrogen. This produces clean weld deposits but is less practical for outdoor applications due to wind. Self-shielded flux-cored wire utilizes specialized chemical compounds within the core that vaporize during welding to form a local protective gas shield, making it ideal for outdoor repairs and open-air field installations.
Tangshan Runxing Machinery Co., Ltd. is the manufacturing and R&D entity. To ensure smooth international business transactions, Hebei Yuwan International Trade Co., Ltd. is authorized to manage export activities. This includes customs documentation, international compliance verification, logistics, and payments, while the factory focuses entirely on quality control and technical support.
Our products are engineered in compliance with DIN 8555 (German standard for surfacing welding products). We evaluate abrasion resistance using the ASTM G65 Dry Sand/Rubber Wheel Test to confirm that the overlay chemistry provides consistent protection against wear under real-world abrasive conditions.
