See ProductIn modern industrial operations, structural integrity and operational uptime are critical components of profitability. Equipment subjected to heavy impact, wear, grinding, and abrasion requires robust protection. As a premier wholesale wire manufacturing manufacturer and supplier, our core focus is addressing these wear mechanisms through metallurgically advanced hardfacing materials and bimetallic chromium carbide overlay (CCO) wear plates.
Unlike standard solid welding wires, flux-cored wires manufactured for hardfacing contain a precisely formulated core of alloy powders inside a cold-formed steel sheath. During the welding process, this core transforms into a highly wear-resistant overlay microstructure. Our manufacturing process controls the carbon-to-chromium ratio to precipitate primary M7C3 chromium carbides within a tough, supportive austenitic matrix. These primary carbides achieve an average hardness exceeding 1500 HV, providing a solid barrier against sliding abrasive minerals, while the surrounding matrix absorbs mechanical impacts.
Globally, industries such as mining, steel production, and cement manufacturing are shifting toward preventive maintenance strategies to lower total cost of ownership. Replacing worn-out components with new castings is no longer economically viable. Instead, engineering teams use hardfacing alloys to rebuild and protect parts locally. By optimizing alloy chemistry and deposition techniques, our products help reduce downtime in processing facilities worldwide, from the high-altitude mines of South America to the coal-fired power stations of Europe.
Our production plant is located in Tangshan, Hebei Province, a region known for its steelmaking infrastructure and metallurgical expertise. This location gives us direct access to high-quality raw materials, including cold-rolled strip steel and refined alloy powders. By managing the supply chain from raw materials to final spooling, we maintain consistent product quality and offering competitive wholesale pricing. Additionally, we partner with Hebei Yuwan International Trade Co., Ltd., which manages international logistics, customs clearance, and secure trade documentation to ensure seamless global delivery.
The hardfacing industry is moving toward automated, high-deposition processes. Our technical development focuses on three main areas:

Abrasion-resistant (AR) steel plates (like AR400 or AR500) are through-hardened carbon steel grades. While tough, their hardness is limited to around 400-500 HB. Chromium Carbide Overlay (CCO) plates, such as our bimetallic composite steel plates, have a deposit layer containing chromium carbides (M7C3) with a hardness exceeding 58-62 HRC (approx. 650-700 HB). This provides significantly higher resistance to sliding abrasion.
It depends on your working environment. Self-shielded flux-cored wires (like our OEM self-shielded series) contain gas-forming components in their core, making them suitable for outdoor and high-wind repairs where gas shielding would blow away. Gas-shielded wires (using CO2 or Argon/CO2 mixtures) produce less fume and spatter, making them preferable for controlled shop settings.

Yes. CCO plates can be cold-formed or rolled into cylinders or cones with the overlay surface facing inward or outward, depending on the minimum radius. They are welded to structures using the mild steel backing plate. The cladding layer itself cannot be structural and is not weldable directly to load-bearing parts.
