Domite® Laminated Wear Plate Product Information -:- For detailed product information, please contact sales. -: ### **Product Technical Data Sheet: Domite® Laminated Wear Plate** --- #### **1. Product Overview** **Domite® Laminated Wear Plate** is a proprietary, ultra-high wear-resistant steel plate engineered for the most demanding abrasion and impact applications. Its unique patented construction features a **bimetallic laminate**, combining a very hard, abrasion-resistant wear face (typically Domite® alloy) metallurgically bonded to a tough, impact-resistant carbon steel backing plate. This dual-layer design delivers the optimal balance of **surface hardness** to resist material loss and **substrate toughness** to withstand heavy impact, bending, and structural loads without brittle fracture. It is a premium solution for extending service life in critical wear areas, significantly reducing downtime and total operational costs in mining, material handling, and heavy industrial sectors. #### **2. Governing Standards & Specifications** As a proprietary product, Domite® Laminated Wear Plate is governed by manufacturer specifications rather than generic international standards. However, its performance is benchmarked against and often exceeds common industry-grade materials. * **Primary Specification:** **Manufacturer's Technical Data Sheets (ThyssenKrupp / Dillinger, or successor entity).** Exact chemistry and processing are proprietary. * **Referenced Industry Standards:** * **Hardness Testing:** ASTM E10 (Brinell), ASTM E384 (Vickers). * **Impact Testing:** ASTM E23 (Charpy V-Notch) on the backing steel. * **Abrasion Resistance:** Benchmarked against ASTM G65 (Dry Sand/Rubber Wheel Abrasion Test) or G75 (Miller Number Slurry Abrasivity Test), though proprietary testing methods are primary. * **Comparable Material Grades:** Its performance is often compared to, and significantly exceeds, that of standard **AR400/AR500** plates, high-chromium **white cast irons**, and ceramic-metal composites. #### **3. Typical Chemical Composition** The exact chemistry of the wear-resistant layer (Domite®) is a closely guarded trade secret but is based on a **high-carbon, high-chromium martensitic alloy**, often with additional carbide-forming elements. | **Layer** | **Key Components** | **Functional Role** | | :--- | :--- | :--- | | **Wear Face (Domite® Alloy)** | **High Carbon (C)**, **High Chromium (Cr)**, Molybdenum (Mo), Vanadium (V), possibly Niobium (Nb). | Forms a dense network of ultra-hard primary and secondary carbides (e.g., M₇C₃) in a hardened martensitic matrix, providing exceptional resistance to abrasion and deformation. | | **Backing Plate** | Low-to-Medium Carbon Steel (e.g., AISI 1020/1045 equivalent). Manganese (Mn) for strength and toughness. | Provides high tensile strength, fracture toughness, and weldability. Absorbs impact energy and supports the hard facing layer. | *Note: The metallurgical bond between the two layers is achieved through a controlled casting or hot-rolling diffusion process, ensuring integrity under extreme stress.* #### **4. Physical & Mechanical Properties** The defining characteristic is the dramatic property gradient from the wear surface to the backing plate. | **Property** | **Wear Face (Domite® Layer)** | **Backing Steel Plate** | **Key Advantage** | | :--- | :--- | :--- | :--- | | **Surface Hardness** | **650 - 750+ Brinell (HBW)**
(Typically **63 - 68 HRC**) | 200 - 300 HBW | Extreme surface hardness for resisting cutting/gouging abrasion. | | **Tensile Strength** | Not primary design metric. High compressive strength. | **Min. 450 - 700 MPa** | Backing plate provides the structural strength to support the assembly. | | **Yield Strength** | Not applicable (brittle layer). | **Min. 350 - 550 MPa** | Prevents plastic deformation of the entire plate under load. | | **Impact Toughness** | Very Low (Brittle). | **High (>20 J at -20°C, Charpy V-Notch typical)** | **Critical Feature:** The tough backing absorbs impacts that would shatter a monolithic hard material, preventing catastrophic failure. | | **Bendability/Formability** | None. Must not be bent. | Good (prior to lamination). | Plate is supplied flat; fabrication is done via cutting and welding only to the backing. | | **Abrasion Resistance** | **Exceptionally High.**
Wear life can be **5-10x** that of standard AR400/500 plate in severe sliding abrasion. | Not applicable. | Directly translates to massively extended service intervals. | | **Relative Wear Index** | Often rated at **> 500%** when compared to mild steel (AISI 1020 = 100%). | N/A | Quantifies the dramatic improvement in service life. | #### **5. Product Applications** Domite® Laminated Plate is specified where unacceptably high wear rates occur on standard steel plates, leading to frequent replacement, safety risks, and high maintenance costs. * **Mining & Quarrying (Primary Market):** * **Truck & Shovel Liners:** Dump truck beds, hoppers, loader buckets (corners, floors, cutting edges). * **Chute & Hopper Liners:** Transfer points, feed chutes, screening hoppers (areas of high-velocity material impact/sliding). * **Crusher & Breaker Components:** Liners, aprons, hammers in impactor applications. * **Material Handling & Processing:** * **Slurry Handling:** Cyclone feed launders, pipe elbows, classifier tanks in mineral processing. * **Ash & Cement Handling:** Fly ash hoppers, clinker screw conveyors, silo discharge cones. * **Wood & Biomass Processing:** Chipper anvils, hogger liners, conveyor skirt boards. * **Construction & Heavy Equipment:** * **Cement Mixer Drum Liners** * **Excavator Bucket Wear Parts** #### **6. Fabrication & Handling Guidelines (Critical)** * **Cutting:** Use only **plasma arc** or **waterjet cutting**. Oxy-fuel cutting will damage the hard face. Grinding is acceptable. * **Welding:** **Weld only to the backing plate.** Never weld on or through the Domite® wear face, as it will crack. Use pre-heat and low-hydrogen electrodes suitable for the backing steel. * **Bending/Forming: Cannot be bent or formed after lamination.** It must be used as a flat plate or pre-formed by the manufacturer. * **Installation:** Bolt or weld (to the back) into position. For welding, use plug welds through holes drilled in the backing or perimeter fillet welds. #### **7. Ordering Information** Specify: **"Domite® Laminated Wear Plate"**. Key details required: * **Total Thickness:** (e.g., 30 mm, with typical wear face being 1/3 to 1/2 of total). * **Dimensions:** (Length x Width). * **Required Hardness Level:** (e.g., "Standard Grade" ~650-700 HBW). * **Backing Steel Grade:** (Typically standard, but can be specified for special structural needs). * **Certification:** Request Manufacturer's Mill Test Certificate for both chemical and mechanical properties of the composite plate. -:- For detailed product information, please contact sales. -: Domite® Laminated Wear Plate Specification Dimensions Size： Diameter 20-1000 mm Length <6516 mm Size:We can customized as required Standard： Per your request or drawing We can customized as required Properties（Theoretical） Chemical Composition -:- For detailed product information, please contact sales. -: Domite® Laminated Wear Plate Properties -:- For detailed product information, please contact sales. -:
