See more products >In modern industrial metallurgy, selecting the appropriate grade of stainless steel or wear-resistant composite is a key operational decision that dictates mechanical longevity, energy efficiency, and cost control.
Historically, heavy industrial systems utilized standard stainless steel grades such as AISI 304 or 316 to counteract environmental corrosiveness and minor wear. However, in aggressive processing zones like mining chutes, coal pulverizers, cement hoppers, and port grab buckets, standard austenitic stainless steel lacks the hardness to withstand high-stress abrasion. This limitation led to the development of Bimetallic Chromium Carbide Overlay (CCO) plates. These plates feature a structural steel base fused with a hyper-eutectic chromium carbide weld overlay, combining toughness with high hardness.
Globally, the steel sector is undergoing a transition driven by carbon neutrality mandates and the rising cost of downtime. Replacing components every few weeks is no longer economically viable. Heavy industries are moving toward tailored alloy profiles. As an OEM factory, Tangshan Runxing Machinery Co., Ltd. addresses this demand by providing high-hardness wear plates, flux-cored wires, and automated repair services designed for high-stress applications.
Off-the-shelf wear components rarely fit specific plant geometries or localized stress fields. The term "OEM Stainless Steel & Alloy Manufacturing" refers to the precise engineering of component dimensions, backing steel grades, and weld overlay chemistry. Custom engineering ensures that structural backing remains weldable and ductile, while the face alloy provides the necessary hardness. For instance, in Cement plants, chute liners must handle dry raw meal abrasion, while in Dredging/Port facilities, they must withstand wet, corrosive slurries. An OEM approach allows for adjustments in chromium, carbon, niobium, and boron concentrations in the hardfacing layer to balance impact resistance, temperature stability, and sliding wear resistance.
| Alloy Type | Hardness Range (HRC) | Primary Wear Mechanism | Ideal Application Scenario |
|---|---|---|---|
| Austenitic Stainless Steel (e.g., SUS 304/316) | 15 - 20 HRC | Corrosive fluid attack, mild friction | Food processing, chemical tanks, piping |
| Hardened Carbon Steel (Q355 / AR400) | 35 - 42 HRC | Structural load bearing, mild impact | Chute bodies, low-wear scrapers |
| Martensitic Stainless & Tool Alloys | 45 - 55 HRC | Moderate impact with slide wear | Crusher jaws, heavy duty turbine parts |
| Bimetallic CCO (e.g., RX®wp 7600 / VAUTID) | 58 - 63 HRC | Extreme sliding abrasion, high stress | Mining liners, cement hopper bins, sinter chutes |
Founded in 2010 in Tangshan, Hebei Province, Tangshan Runxing Machinery Co., Ltd. specializes in the R&D, manufacturing, and on-site engineering of wear-resistant surfacing products. The factory produces CCO wear plates, custom-fabricated wear liners, hardfaced elbow pipes, flux-cored wires, and automated surfacing machinery.
Under the leadership of General Manager Li Xiuhua and Vice General Manager Cui Jianying, the company maintains research partnerships with academic institutions, including Tangshan University's research team led by Dean Yuan Shaoqiang, Vice Dean Li Jing, and Professor Yang Yuehui. This collaboration supports development in metal cladding microstructure refining, high-temperature hardness maintenance, and carbide distribution optimization.
Additionally, Runxing Machinery has been an authorized agent of VAUTID Germany since 2019, incorporating global wear alloy standards into its domestic manufacturing processes. The company's products are exported internationally through Hebei Yuwan International Trade Co., Ltd., which manages shipping compliance, customs clearance, and logistics documentation.
Equipment availability is critical in cement processing. Raw meal feed chutes, cyclones, classifier cones, and vertical roller mill guides are subject to continuous dry particle wear. Standard steels degrade rapidly in these conditions, leading to unplanned shutdowns. Implementing CCO wear plates and on-site roller surfacing helps maintain system availability.
