Wuxi Jietai Machinery Trade Co., Ltd. is one of the most professional hardfacing wear plates manufacturers and suppliers in China. Welcome to wholesale customized hardfacing wear plates at competitive price from our factory. Good service and quality products are available.
Bimetal hardfacing wear plates are designed to provide superior wear resistance in highly abrasive environments.
These plates consist of a base layer of mild steel or stainless steel, onto which a hard, wear-resistant alloy is deposited through welding or other metallurgical processes. This combination results in a composite material with enhanced durability and service life.
Bimetalic Wear Plates are composite materials engineered through advanced metallurgical bonding technigues tocombine the hioh wear resistance of a hardened aloy laver with the structural touohness of a ductile base laver. Theseplates are specifically designed to withstand extreme abrasion, impact, and corrosion in industries such as mining.construction, and heavy machinery.
Hardfacing Wear Plates Material Composition
Top Layer (Cladding):
Alloy Type: High-chromium (Cr15%-30%), molybdenum (Mo2%-5%), and carbide-forming elements (e.g., vanadium,
tungsten).
Hardness: 550-700 HBW (Brinell Hardness) to resist gouging, grinding, and sliding wear.
Microstructure: Hyper-eutectic chromium carbides distributed in a martensitic matrix
Base Layer (Substrate):
Material: Low-carbon steel (e.g., ASTM A36, S355]R) or high-strength steel (e.g., Hardox 400).
Thickness: 6-100 mm (customizable based on load requirements).
Function: Absorbs impact energy and provides structural support.
Key Features
- High Wear Resistance: Advanced bimetallic composition ensures prolonged service life under extreme abrasion.
- Superior lmpact Strength: Designed to withstand heavy impacts without cracking or deformation.
- Customizable Dimensions: Available in various thicknesses and sizes to meet specific application needs.
- Easy Installation: Can be cut, welded, or bolted for seamless integration into existing systems.
- Cost-Effective: Reduces maintenance costs and downtime with long-lasting performance.
Manufacturing Process
Bimetallic wear plates are produced through a specialized manufacturing process that combines a tough base material with a hard, wear-resistant overlay. This process ensures exceptional durability and performance in high -wear environments. Below is an overview of the key steps involved in creating our high-quality bimetallic wear plates.
Bonding Technology
Explosive Cladding
Hiah-pressure explosion welds the clad layer to the substrate, ensuring 100% metallurgical bonding without porosity.
Casting Overlay
Molten wear-resistant alloy is poured onto the preheated base plate, followed by controlled cooling to prevent cracking.
Post-Processing
Stress-relief annealing to eliminate residual stresses
Surface grinding for dimensional accuracy (+0.5 mm tolerance)
Quality Assurance
Non-Destructive Testing (NDT):
Ultrasonic testing (UT) to detect bonding defects.
Dye penetrant inspection (DPl) for surface cracks
Applications
Bimetalic wear plates offer an effective solution for industries facing challenging wear conditions. By combining the hardness of white iron with the toughness of steel, these plates enhance equipment longevity and performance. When selecting a supplier, consider factors such as product quality, customization capabiities, and industry experience toensure optimal results for your specific applications.

Our Chromium Carbide Wear Plate Products
Overlay Clad Wear Plate is an overlay weld resistant to the formation of a wear-resistant layer based on Cr7C3 carbide with a volume fraction of 50% or more on a common steel plate (Q235(A3) or heat-resistant steel (15CrMo, 12Cr1MoV, etc.) or stainless steel plate.
Bimetallic wear plate has high wear resistance, impact resistance, deformable and weldable performance characteristics, like steel plates can be directly rolled plate deformation, cutting and punching and other processes, processing into wear-resistant parts.
