Explore Specs >The Greater Philadelphia area and the Delaware Valley have historically stood as the backbone of East Coast American heavy industry. From the bustling port complexes of PhilaPort, handling millions of tons of dry bulk and raw materials, to the historic steel processing mills and power plants spanning Pennsylvania, the demand for durable materials is relentless. Severe wear and tear on industrial equipment cost companies millions in unplanned downtime and structural replacements.
As modern plants pivot to advanced automation, mitigating mechanical degradation becomes a bottom-line priority. High-hardness chromium carbide overlay (CCO) wear plates, bimetallic liners, and specialized hardfacing welding wires have transitioned from simple maintenance patches to critical strategic components. Utilizing state-of-the-art cladding technologies, local operations can achieve up to a 10x lifespan extension compared to standard structural steel.
By implementing bimetallic CCO liners instead of traditional AR400/500 carbon steels, industrial facilities achieve massive savings:
Understanding wear patterns, carbide morphology, and performance optimization in high-stress industrial zones.
Our proprietary overlay alloys feature a hypereutectic microstructure containing a high volume fraction of primary M7C3 chromium-rich carbides.
Chromium (Cr): 25% - 35%
Carbon (C): 4.0% - 5.5%
Base Material: Q235B / Q355B Structural Carbon Steel
Hardness Range: 58 - 62 HRC (Vickers Hardness: 600 - 800 HV)
The wear resistance of bimetallic overlay plate depends on the concentration and structure of primary chromium carbides. During the cooling phase of open-arc weld overlay cladding, the excess carbon and chromium crystallize into hexagonal primary M7C3 carbides. These carbides have a hardness level of up to 1500 HV, providing a robust barrier against sliding and scraping abrasion.
By embedding these ultra-hard carbides in a tough, resilient iron-based matrix, the plate achieves dual-performance capabilities. The hard carbides resist aggressive abrasive media, while the mild steel backing absorbs impact stresses, preventing fracture during high-vibration operations. This combination is ideal for coal feeders, sand processing systems, and heavy bucket elevator chutes.
Tangshan Runxing Machinery Co., Ltd. uses state-of-the-art cladding equipment to control the dilution of the base material. This ensures that the wear-resistant overlay maintains its chemistry and performance, even in the first 1-2mm of the weld deposit.

The manufacturing landscape is undergoing a digital and materials-science revolution. The modern industrial sector demands wear plates that not only last longer but also withstand higher temperatures and chemical environments. The next generation of bimetallic wear liners leverages complex alloy formulations, including additions of Niobium (Nb), Boron (B), and Titanium (Ti).
These complex carbides are smaller and more evenly distributed than standard chromium carbides. This structure increases toughness, reducing the micro-cracking common in high-impact operations. Below is our R&D roadmap for surface protection materials:
Our global clients benefit from a structured supply chain. While our manufacturing facility in Tangshan focuses on advanced alloy R&D and automated cladding production, all export activities—including international logistics, customs clearances, marine freight booking, and financial settlement—are managed by Hebei Yuwan International Trade Co., Ltd.
This partnership ensures reliable international shipping, short lead times, and seamless delivery to the Port of Philadelphia and the broader US East Coast.
Expert insights on selecting, installing, and optimizing Chromium Carbide Overlay (CCO) wear plates.
Traditional AR500 plates are hardened carbon steels that rely on heat treatment for wear resistance. CCO plates feature a composite structure: a mild steel base plate with a welded chromium carbide overlay. The primary chromium-rich carbides (M7C3) reach a hardness of up to 1500 HV. This structure offers superior sliding wear resistance, outlasting AR500 by up to 5 to 10 times in abrasive applications.
Relief cracks are normal and occur during the cooling phase of weld cladding. They are a sign of proper stress relief, preventing the plate from warping or cracking the structural backing during installation or service. These cracks do not compromise the plate's structural integrity or performance.
Yes. While the hard overlay layer cannot be easily machined, the carbon steel backing can be welded to support structures. The plate can be cut using plasma arc, water jet, or carbon arc gouging from the mild steel backing side. This makes field installation and replacement efficient.
Our products undergo quality control testing, including chemical analysis, hardness mapping, and thickness checks. Export logistics and documentation are managed by Hebei Yuwan International Trade Co., Ltd., ensuring seamless customs clearance and safe shipping to North American, European, and Central Asian markets.
