Bimetal Wear Resistant Steel Plate

Product Overview

Bimetal Wear Resistant Steel Plates (Chromium Carbide Overlay Plates) are high-performance engineered wear solutions designed to eliminate severe abrasion and impact failures in heavy industrial equipment.
By metallurgically bonding a high-chromium carbide wear-resistant overlay onto a ductile structural steel base plate, this composite material delivers:
Extreme Surface Hardness: Resists severe abrasive jetting and sliding wear.
High Impact Absorption: The ductile base absorbs dynamic shocks, preventing structural cracking.
Structural Integrity Under Heavy Load: Maintains flatness and strength in high-stress environments.
Long-Term Operational Stability: Maximizes equipment uptime in harsh conditions.

Technical Specifications

Key Performance Advantages

High Hardness Wear Surface
• Surface hardness: 58–65 HRC
• Dense chromium carbide microstructure
• Excellent resistance to mineral abrasion and sliding wear

Impact & Crack Resistance
• Ductile base steel absorbs impact energy
• Reduces brittle fracture risk compared to fully hardened steels
• Suitable for dynamic loading systems

Metallurgical Bond Reliability
• Fully fused overlay welding process
• No mechanical adhesion failure
• Stable performance under long-term industrial operation

Fabrication & Processing Flexibility
Supports standard industrial fabrication:
• CNC / plasma / laser cutting
• Controlled bending (application dependent radius)
• Welding with appropriate consumables
• Bolt-on or weld-on installation systems

Lifecycle Cost Advantage
Although initial material cost is higher than AR steel:
Typical service life is 2–5 times longer, resulting in:
• Lower replacement frequency
• Reduced maintenance downtime
• Lower total cost of ownership (TCO)

Common Industrial Applications

Mining & Mineral Processing
• Crusher & Chute Liners: Eliminates frequent gouging wear and costly unplanned shutdowns.
• Excavator & Dragline Buckets: Protects critical structural lips and floors from high-impact rock abrasion.
• Hopper & Feeders: Resolves material-flow erosion and wall thin-out issues.

Cement & Aggregate Production
• Raw Material Chutes: Resists continuous, high-velocity abrasive clinker and limestone flows.
• Vertical Roller Mill (VRM) Parts: Extends the service life of separator vanes, body liners, and ducts.
• Cyclone Separators: Prevents localized dust erosion and micro-particle wear.

Power Generation & Coal Handling
• Coal Pulverizer & Transfer Pipes: Withstands long-term sliding abrasion from pulverized coal.
• Exhauster Fan Blades & Ash Systems: Resists fly-ash erosion under elevated operating temperatures.

Steel & Iron Mills
• Sintering & Coke Plant Liners: Survives high-temperature, highly abrasive raw material feeding systems.
• Blast Furnace Charging Chutes: Handles heavy, sharp slag and iron ore impact.

Thickness Selection Guide

5+3 mm / 6+4 mm: Ideal for light-to-medium sliding abrasion, dust ducting, and low-impact material chutes.

8+4 mm / 8+6 mm: The industry standard for medium-impact mining hoppers, cement chutes, and conveyor skirt boards.

10+6 mm / 12+6 mm: Engineered for high-stress zones including crusher liners, heavy-duty truck beds, and primary hoppers.

12+12 mm / Customized Thick Overlays: Designed for extreme heavy-duty industrial conditions involving high-velocity impact with severe abrasion.

Fabrication & Installation Capability

Cutting: CNC Plasma Arc Cutting is highly recommended from the base plate side. Waterjet cutting can be utilized for high-precision tolerances.

Forming/Bending: Cold forming can be performed. The plate should be rolled with the overlay on the inside (concave) or outside (convex) according to specified minimum bending radiuses.

Welding: The structural base layer can be welded using standard low-hydrogen wires (E7018 type). The overlay layer can be hardfaced at joints using chromium carbide wires to maintain continuous wear protection.

Mounting Methods:
• Direct structural welding (welding the base steel to the equipment).
• Pre-fabricated countersunk bolt-on liners.
• Stud welding / plug welding from the back.

Comprehensive Quality Control (QC) System

Hardness Uniformity Testing: Multi-point Rockwell C (HRC) testing across the sheet surface.

Ultrasonic Bonding Inspection: Verifies the 100% integrity of the metallurgical interface.

Microstructure & Carbide Verification: Laboratory checks to confirm Cr7C3 carbide volume fraction and distribution.

Surface Crack Management: Inspection of controlled stress-relief cracks (inherent to high-quality overlay, ensuring plate flatness and flexibility).

Dimensional Tolerance Control: Strict verification of length, width, thickness, and diagonal diagonal squareness tolerances.
