Overview
We are a direct manufacturer of bimetallic impact-resistant wear plates, supplying EPC contractors, mining operators, cement plants, and industrial distributors worldwide.
Our solution is engineered for combined abrasion and high-impact working conditions, where conventional AR steels often fail due to cracking, rapid wear loss, or structural delamination. The product consists of:
• A ductile structural steel base layer
• A high-chromium carbide wear-resistant overlay
• A metallurgical bonding interface ensuring long-term structural integrity
This structure provides a controlled balance between impact absorption and wear resistance, enabling stable performance in severe industrial environments.
Field Application Experience
Our wear plates are applied in continuous heavy-duty environments, including:
• Ore chute liners (iron, copper, gold)
• Crusher discharge zones
• Hopper and feeder systems
• High-impact transfer points
• Clinker transport systems
• Raw material hoppers
• Kiln feed chutes
• Vertical mill inlet sections
• Coal transfer stations
• Port unloading systems
• Conveyor transition zones
Engineering Design Principle
Impact-Resistant Base Layer
• Material: Q235 / Q345 equivalent structural steel
• Function: Absorbs mechanical shock from large particle impact
• Prevents brittle fracture under dynamic loading
High-Chromium Carbide Wear Layer
• Hardness: 58–62 HRC (600–700 HBW)
• Microstructure: Cr₇C₃ primary carbide network
• Function: Resists sliding abrasion and particle erosion
Metallurgical Bond Interface
• Fusion-based cladding process
• No adhesive or mechanical bonding
• Eliminates delamination risk under thermal and mechanical stress

Field Performance Experience
Based on long-term industrial usage feedback:
• Service life extension: typically 3–8× compared with AR steel liners
• Reduced maintenance shutdown frequency in high-wear zones
• Improved structural stability in impact-dominant applications
• Lower failure rate in high-load transfer points
Performance is dependent on system design, material flow velocity, and particle hardness.
Failure Mode Engineering
Conventional AR steel typically fails due to:
• Brittle cracking under repeated impact
• Rapid surface wear in abrasive flow
• Heat-related microstructural degradation
• Delamination in composite plates
Our bimetallic system addresses these issues by:
• Separating load-bearing and wear-resistance functions
• Absorbing impact through ductile base steel
• Protecting surface through carbide-rich overlay

Lifecycle Cost Analysis
Industrial buyers evaluate total operational cost rather than unit price. Key cost drivers:
• Service life duration
• Replacement frequency
• Production downtime cost
• Labor and installation cost
In high-wear environments, total cost per operating hour is significantly reduced compared to conventional AR steel solutions.
