What is a Wear-Resistant Alloy Lining Plate?
Wear-resistant alloy lining plates are high-hardness, wear-resistant metal components installed on the inner walls of equipment in industries such as mining, cement, metallurgy, and power plants.
They are primarily designed to resist severe scouring and abrasion from ores and gravel while withstanding impact and extrusion from bulk materials, thereby preventing direct wear, deformation, or cracking of the equipment shell.
This effectively extends service life, reduces shutdown frequency, and lowers subsequent maintenance costs.
These plates are widely used on the inner walls and end covers of ball mills, in cavity protection and internal guard positions of various crushers, and as inner lining protection for material conveying equipment operating under high-temperature, high-dust, and severe wear conditions.
The product is available in a wide range of shapes, including rectangular, curved, trapezoidal, and other conventional styles.
Bolt holes, positioning grooves, and chamfered edges can be incorporated for ease of installation and fixing. All specifications can be customized based on equipment conditions and supplied drawings.

Selection & Comparison of Wear-Resistant Alloy Lining Plates
1. High-chromium Cast Iron KmTBCr26 ,(BTMCr26)This material features high overall hardness, a dense microstructure, and superior wear resistance with uniform hardness, making it resistant to deformation and cracking.As the top-grade option in the high-chromium series, it is compatible with resin sand casting, offering good surface precision and the longest service life.
It is best suited for low-impact, severe wear, and strong scouring scenarios, and is ideal for the inner lining of ball mills, vertical mills, cement clinker mills, and for grinding high-hardness materials such as iron ore, granite, and quartz sand.
2. High-chromium Cast Iron Cr20,With wear resistance second only to Cr26, this material offers stable hardness and high cost performance, striking a favorable balance between wear resistance and cost.
It is suitable for medium-to-high wear conventional conditions and is commonly used in small and medium-sized mine mills, slag conveying linings, and internal protection linings for ordinary crushers.
3. High-chromium Cast Iron Cr15,As an entry-level high-chromium material, Cr15 provides better wear resistance than ordinary alloy steel at a lower cost.
It is suited to moderate wear applications without heavy impact, and is typically applied in small chutes, hopper linings, and light-wear protection areas with low dust exposure.
4. Bimetallic Composite (High-Chromium + High-Manganese Alloy),The working surface employs high-chromium alloy for strong wear resistance, while the base layer utilizes high-manganese alloy for excellent impact resistance, combining the dual advantages of wear and impact resistance for the best overall performance.
This material is designed for complex conditions involving both severe wear and high impact, and is widely used in heavy hammer crushers, coarse crushing chambers in large mines, and demanding locations where bulk hard ores subject the lining to simultaneous impact and scouring.
5. High-manganese Steel (Hadfield Steel),High-manganese steel possesses a distinctive work-hardening characteristic: under intense impact and extrusion, its surface hardness increases significantly while the core retains good toughness, meaning it becomes more wear-resistant as it wears.
This material offers the most outstanding impact resistance in the high-manganese series, making it suitable for high-impact, medium-to-low wear conditions. It is commonly used in jaw crusher liners, heavy hammer crusher liners, and protective liners in areas subjected to bulk material impact.
Process Comparison
| Comparison Dimension | Resin Sand Casting | Water Glass Sand Casting | Lost Foam Casting |
|---|---|---|---|
| Surface Precision | High flatness, free of obvious casting defects such as sand holes, small dimensional error, high assembly accuracy | Rough surface, large tolerance deviation, moderate appearance, requires subsequent processing | Smooth surface, no parting lines, no flash or burrs, small dimensional deviation |
| Product Structure | Compatible with regular plates, curved plates, and perforated/grooved complex structures, meeting conventional and complex structural demands of mill and crusher lining plates | Only suitable for simple regular styles, not applicable for complex hole positions or special-shaped structures | Excels in special-shaped, curved, thin-walled, and complex special structures, ideal for special-shaped lining plates |
| Batch Adaptability | Suitable for medium and large mass production with stable quality, ideal for large-scale orders | Suitable for small-batch orders with flexible production, not fit for large-scale mass production | Suitable for medium and small batches of complex parts with moderate production efficiency; high mold cost for mass production |
| Internal Quality | Dense internal structure, few casting defects, uniform and stable hardness, good wear and crack resistance, ideal for high-chromium cast iron lining plates | Relatively loose structure, prone to air holes and sand holes, medium wear resistance, suitable for conventional low-demand lining plates | Few internal defects, high material density, excellent quality, better wear resistance than ordinary sand casting |
| Cost & Lead Time | Medium to high cost, suitable for mid-to-high-end lining plate orders; unit cost can be moderately reduced in mass production; moderate cycle with stable mass delivery | Lowest cost, economical and practical, low mold investment, suitable for budget-limited conventional orders; short cycle and relatively fast delivery | Relatively high cost, significant upfront foam mold investment, higher unit cost than resin sand casting, suitable for complex structure orders; slightly longer initial cycle, controllable delivery for medium and small batches |
