Hanoi, the key administrative and economic center of Northern Vietnam, has experienced an unprecedented surge in heavy manufacturing, infrastructural investment, and logistics processing. Spanning across its core industrial hubs like the Thang Long Industrial Park, Sai Dong B Industrial Zone, and neighboring logistics corridors in Bac Ninh and Hai Phong, the requirement for wear management has shifted from commodity-grade structural steels to advanced material solutions.
Industrial machinery operating in Hanoi's concrete batching plants, coal power stations, and limestone processing zones faces compounding stresses. Traditional quenched-and-tempered (Q&T) steels fall short in environments that combine high temperature with extreme abrasion, leading to frequent system down-time. Tangshan Runxing Machinery’s premium Chromium Carbide Overlay (CCO) Wear Plates solve this bottleneck by introducing a high-density primary chromium carbide phase (M7C3) structurally bonded to a ductile steel backing plate.
The metallurgical matrix of CCO wear plates contains a carbon volume fraction of 3.5% to 5.5% and a chromium fraction of 25% to 35%. This precise chemical balance yields primary Cr7C3 chromium carbides oriented perpendicular to the wear surface. This microstructural orientation allows the plate to withstand persistent scratching abrasion under severe load, keeping equipment like chutes, mill fan blades, and raw material silos in service up to 10 times longer than standard AR400 or carbon steels.
Our tech roadmap aims for zero-dilution wear solutions. By leveraging automated cladding machinery with optimized voltage controls, our production lines achieve a stable fusion zone with minimal iron dilution from the base plate. This guarantees that the surface performance is consistent throughout the entire thickness of the hardfaced layer.
Composite material wear plate made of structural steel backing and hard weld surfacing. RX®wp 7600 corresponds to DIN 8555 standards, guaranteeing consistent surface performance.
Self-shielded flux cored wire. High chromium alloy engineered to resist high-stress grinding abrasion with low impact. Excellent for overlay repairs on-site.
Advanced hardfacing overlay application designed to tackle heavy industrial wear under low-impact, high-abrasion working conditions.
RX® Surfacing system features high automation, multiple welding torches, and customizable swing paths. Excellent for producing wear plate laminates and repairing grinding rolls.
Complete mechanical processing capabilities including precision CNC cutting, countersinking, rolling, and custom drawing fabrication for wear-resistant components.
Specialized re-surfacing technology for grinding rollers, vertical coal mill tables, and steel mill rollers to extend component lifespan and lower maintenance overheads.
Tangshan Runxing Machinery’s manufacturing complex uses smart hardfacing welding systems designed in-house to maintain uniform wear plate output. By combining automated raw material feeding, advanced cladding temp controls, and online ultrasonic checks, we guarantee consistent quality across every batch.
When purchasing wear plates for Hanoi projects, consistency is a key factor. Variation in the hardness of the surfacing layer or poor bonding with the backing plate can lead to cracking and delamination under severe impact. Our automated manufacturing line controls dilution rates to under 10% on the first layer, preserving the high concentration of chromium carbides and ensuring robust wear protection from day one.

Standard quenched-and-tempered (Q&T) steel plates like Hardox rely on martensitic hardness (typically 400–500 HBW) throughout the steel alloy. In contrast, CCO plates feature a mild backing plate overlaid with a layer of chromium carbide. This layer contains primary Cr7C3 carbides with a microhardness of 58–62 HRC (around 700–800 HBW). Under severe sliding abrasion, CCO plates outlast Q&T steels by 4 to 10 times, making them highly cost-effective for high-wear zones.
Yes. Our wear plates can be formed and welded. They can be cold rolled to a minimum radius depending on the plate thickness (typically 20-30 times the plate thickness) with the hardfacing layer on the inside or outside. Welding is straightforward because the structural backing layer is made of weldable carbon steel (such as Q235B or Q345B). You can weld the backing plate directly to your machine's structure or use plug weld holes, stud bolts, or custom countersunk fasteners.
Stress-relief cracks are a normal characteristic of bimetallic CCO plates. They occur during the cooling phase of the weld surfacing process to relieve residual thermal stresses. These cracks run perpendicular to the bead direction and stop at the boundary of the ductile carbon steel backing. They do not compromise the plate's structural integrity or wear resistance; instead, they prevent warping during installation and operation.
