View Details"As Riyadh accelerates its massive infrastructure and economic expansion under Saudi Vision 2030, heavy industrial installations require advanced materials to combat extreme abrasion, impact, and high ambient temperatures."
Riyadh has evolved into the central powerhouse of the Middle East’s construction, mining, and industrial sectors. The execution of gigaprojects such as the King Salman Park, Qiddiya, and the massive expansions in Riyadh's industrial zones has created an unprecedented demand for reliable bulk material handling systems. The regional environment—characterized by abrasive desert silica sand, extreme summer temperatures exceeding 50°C, and heavy duty cyclical loads—creates harsh operating conditions for plant machinery.
Standard mild or carbon steels succumb quickly to severe abrasive wear under these conditions, leading to unexpected plant shutdowns, high maintenance costs, and costly production losses. To mitigate these failures, modern plant managers in Riyadh are increasingly turning to advanced tribological materials, particularly Chromium Carbide Overlay (CCO) wear plates and bimetallic composites.
Runxing Machinery, in close coordination with our global export arm Hebei Yuwan International Trade Co., Ltd., offers high-end solutions engineered to meet these challenges. By incorporating advanced metallurgical compositions, our wear plates offer unmatched protection, significantly extending the service life of cement chutes, hopper liners, mining skip guides, and coal grinding components.
Our automated cladding processes ensure a high volume fraction of primary Cr7C3 carbides (typically 30–50%) oriented perpendicular to the wear surface, offering exceptional wear resistance.
Achieving a consistent bulk hardness of 58 to 62 HRC. This hardness is sustained throughout the entire overlay thickness, avoiding premature failure near the fusion zone.
By cladding the hardfacing layer onto tough structural backing steels like Q235B or ASTM A36, we ensure the plate can absorb high impact without structural cracking.
The performance of a chromium carbide overlay wear plate is largely determined by its microstructure. During our specialized open-arc or submerged-arc welding processes, chromium and carbon dissolve in the weld pool and crystallize to form primary hexagonal M7C3 chromium carbides. These carbides have a micro-hardness ranging from 1200 to 1600 HV (Vickers), which is significantly harder than standard silica sand and many mined minerals.
When abrasive media slides across the surface, the hard primary carbides act as barriers, preventing the abrasive particles from cutting into the matrix. The matrix itself, consisting of a tough eutectic mixture of austenite and carbides, supports the primary crystals, ensuring they do not break under impact.
For major industrial operations in Riyadh, this means that equipment handling materials like limestone, clinker, iron ore, and hard rock can operate continuously for months—and in many cases, years—without needing replacement liners. The reduction in downtime has a direct, positive impact on plant operational efficiency and profitability.
Chutes, vertical mill rollers, and separator fan blades are subject to intense abrasive dust and hot gas flows. Our custom CCO plates ensure continuous, reliable operation.

"We invest in ongoing R&D to push the performance limits of surfacing alloys, supporting Saudi Arabia's growing manufacturing sectors."
As heavy industrial plants adopt digital twins and smart tracking, Runxing Machinery is developing smart wear liners with built-in sensors. These liners monitor real-time thickness and predict maintenance intervals, reducing unplanned downtime.
At the same time, we focus on lowering the environmental footprint of our wear plates. By optimizing our manufacturing processes and designing wear liners with a longer service life, we help our clients lower their total carbon footprint. This aligns with Saudi Arabia's goals for sustainable industrial growth under Vision 2030.
