Browse PTTA >In the heavy industrial sectors such as global cement production, iron & steel manufacturing, minerals mining, power generation, and dry bulk port handling, mechanical wear is a relentless and costly operational vulnerability. The evolution of high-strength wear-resistant steel and Chromium Carbide Overlay (CCO) plates represents the technological frontier in mitigating downtime and optimizing total cost of ownership (TCO). Modern manufacturing facilities demand OEM solutions that not only possess extreme surface hardness but also maintain mechanical structural integrity under cyclical dynamic stress and high-impact conditions.
Supply chain directors and maintenance engineers globally face an array of challenges when purchasing wear-resistant steel. Standard low-carbon or low-alloy wear plates often fail to withstand the severe abrasive mechanisms presented by bulk material handling. As a result, critical equipment parts such as raw mill liners, mining chutes, and coke dust extraction ducts undergo premature failure. Strategic sourcing must emphasize materials that incorporate a high volume fraction of primary Cr7C3 chromium carbides embedded within a tough eutectic matrix.
At Tangshan Runxing Machinery Co., Ltd., we resolve these challenges by offering engineered OEM and ODM bimetallic wear solutions. By utilizing advanced welding automation systems alongside high-alloy hardfacing wires, our composite plates deliver consistent hardness depth profiles, outlasting traditional structural carbon steels by up to 10 to 15 times under intensive abrasive wear stress.
The wear resistance of a Chromium Carbide Overlay is not determined solely by bulk hardness. The distribution, geometry, and volume fraction of primary hexagonal M7C3 chromium carbides play a critical role. A matrix featuring a minimum of 30-40% volume fraction of these carbides oriented perpendicular to the wear surface provides the ultimate barrier against hard abrasive particles, such as silica, quartz, clinker, and iron ore.
Established in 2010 in Tangshan, Hebei Province—the heart of China's heavy industrial and metallurgical region—Tangshan Runxing Machinery Co., Ltd. has grown into a leading research-driven manufacturer of hardfacing wear-resistant metal products. Our factory specializes in the complete R&D, design, testing, production, and on-site repair services of wear plates, pipes, automatic welding equipment, and custom component fabrications.
We operate on the fundamental principles of **"Integrity, Superior Quality, Innovation & Sustainable Development."** To provide our international buyers with a secure transaction structure, all overseas export operations are managed through Hebei Yuwan International Trade Co., Ltd. This strategic partnership ensures professional logistics, customs clearance compliance, and secure multi-currency payment handling, letting our factory focus purely on metallurgical quality control and manufacturing precision.
Availabilty of raw mills, cyclones, hopper liners, and vertical coal mill rollers determines cement plant uptime. Our high-hardness CCO liners protect critical structures against the extreme abrasion of raw limestone and high-temperature clinker.

ISO 9001:2015 Quality StandardsThe primary wear resistance in CCO plates is derived from the high volume fraction of primary Cr7C3 chromium carbides (possessing a micro-hardness in the range of 1200-1600 HV) distributed within a tough eutectic matrix. The carbides are oriented perpendicular to the abrasive path, creating a high-hardness barrier that resists sliding, gouging, and erosive wear mechanisms.
We utilize our proprietary automatic surfacing machines, which control welding parameters like heat input and overlay dilution. Together with in-house spectroscopic chemical analysis and hardness testing, we verify that each plate batch matches the specified chromium, carbon, and other alloy chemistry requirements.
This division of labor allows the Tangshan Runxing manufacturing plant to focus entirely on production quality and technological R&D. Hebei Yuwan International Trade handles logistics, export compliance, shipping documents, and payment processing, facilitating smooth international transactions.
Yes, our bimetallic composite plates consist of a weldable base backing plate (typically ASTM A36 or Q235B structural carbon steel) and the hardfacing overlay. They can be rolled, cut using plasma arc processes, and plug-welded from the backside to fit chutes, hoppers, and vertical mill casings.
Our collaboration with Tangshan University's Metal Materials and Forming Technology team, led by Professor Yang Yuehui, provides access to advanced metallurgical research. This partnership allows us to test material formulations, optimize overlay matrix structures, and develop complex alloy wires for high-impact applications.
Self-shielded flux-cored wires (for hardfacing) contain their own gas-generating compounds inside the core. This eliminates the need for external shielding gas systems, making them highly suitable for outdoor repairs, high-wind environments, and remote mining or port facilities.
