Jaw Crusher Plates
Mn18 / Mn22 | TiC Inserts Available
High-performance jaw crusher plates including fixed and moving jaw dies designed for mining, quarry and aggregate crushing operations.
What Jaw Crusher Plates Do and Why Material Matters
Jaw crusher plates (also known as jaw dies) are the primary wear components in jaw crushers. The fixed jaw plate is mounted on the stationary frame, while the swing jaw plate is attached to the moving jaw. Together they form the crushing chamber that compresses rock and ore through repeated mechanical force.
The performance and service life of jaw plates depend largely on the material composition and crusher operating conditions. Our jaw crusher plates are manufactured from high manganese steel grades including Mn13Cr2, Mn18Cr2 and Mn22Cr2, which provide excellent impact resistance and work-hardening capability during crushing operations.
For highly abrasive materials, we also offer advanced manganese steel plates reinforced with titanium carbide (TiC) inserts, such as Mn18Cr2+TiC and Mn22Cr2+TiC. These reinforced designs significantly improve wear resistance and extend service life in demanding mining and quarry applications.
Selecting the correct material grade helps optimize wear life, crushing efficiency and overall operating cost.

Manganese & TiC-Reinforced Materials for Jaw Crusher Plates
High Manganese Steel (Mn13Cr2–Mn22Cr2)
High Manganese Steel (Mn13Cr2–Mn22Cr2)
High manganese steel remains the industry-standard material for jaw crusher plates due to its work-hardening properties under high impact loads. During crushing, the surface rapidly hardens while maintaining a tough and ductile core, ensuring excellent resistance to abrasion and impact fatigue.
We supply multiple manganese grades tailored to different crushing conditions:
• Mn13Cr2 – Cost-effective solution for low to medium impact primary crushing
• Mn18Cr2 – Balanced wear resistance and toughness for general mining applications
• Mn22Cr2 – Higher manganese content for heavy-duty and high-impact feed conditions
Selecting the appropriate manganese grade helps optimize wear life and reduce downtime.
Titanium Carbide (TiC) Insert Jaw Plates
Titanium carbide (TiC) reinforced jaw plates combine ultra-hard carbide inserts with a high manganese steel base. The carbide zones significantly improve abrasion resistance, while the manganese matrix absorbs impact energy to prevent brittle failure.
Key advantages:
• Up to 2–3× wear life in abrasive secondary crushing
• Reduced liner replacement frequency
• Lower total operating cost per ton
• Ideal for quartzite, granite and ultra-hard rock
Not recommended for uncontrolled oversized feed with excessive point-load impact.
Jaw Plate Material Selection By Application
Selecting the right manganese steel grade is critical for crusher performance and wear life.
The following guide compares common jaw crusher plate materials and their typical applications.
| Material | Hardness Range | Impact Resistance | Typical Applications |
|---|---|---|---|
| Mn13Cr2 Manganese | 180–220 HB (work-hardens to 450–500) | Very High | Limestone, secondary crushing, moderate impact |
| Mn18Cr2 Manganese | 210–240 HB (work-hardens to 500–550) | Very High | Hard rock secondary and tertiary crushing |
| Mn22Cr2 Manganese | 220–260 HB (work-hardens to 550–580) | Very High | Highly abrasive rock, mining applications, high-impact crushing conditions |
| Mn18Cr2 + TiC Composite | Mn base + TiC inserts | High | Highly abrasive rock, extended wear life applications |
| Mn22Cr2 + TiC | Base manganese + TiC inserts | High | Extreme abrasion where standard manganese wears quickly |
Note: Actual wear life depends on feed material hardness, crusher settings, feed distribution and operating conditions. Selecting the correct manganese grade helps optimize crusher performance and operating cost.
Jaw Plate Tooth Profile Selection
Tip: Match feed F80 (80% passing size) with the crusher chamber opening to maintain stable crushing performance.
| Tooth Profile | Best For | Description |
|---|---|---|
| Standard Corrugated | General quarrying | Balanced wear pattern and stable grip on most rock types |
| Deep Tooth | Large feed material | Improves grip on oversized rocks and enhances crushing efficiency |
| Super Grip | Slabby or flat material | Aggressive tooth design prevents material slipping |
| Flat (Smooth) | Recycling and sticky material | Reduces material buildup and prevents jamming |
| Recycling Profile | C&D and mixed demolition feed | Handles mixed materials including occasional tramp metal |
Jaw Plate Wear Management Guide
| Wear Stage | Recommended Action | Purpose |
|---|---|---|
| 30–40% wear | Flip the fixed jaw plate 180° | Exposes an unworn crushing face and extends service life |
| 50–60% wear (total) | Flip the swing jaw plate 180° | The swing jaw typically wears faster near the discharge end of the chamber |
| CSS approaching minimum | Replace both jaw plates | Worn plates can no longer maintain safe closed-side setting |
Inspection Before Flipping
Always inspect jaw plates for cracks before flipping.
Cracked plates should be replaced instead of flipped, as cracks may propagate under stress and lead to unexpected failure.
Also check mounting holes and fasteners for elongation, wear or damage.

Jaw Crusher Plate FAQs
What is the difference between fixed and swing jaw plates?
The fixed jaw plate is mounted on the stationary jaw frame, while the swing jaw plate is attached to the moving pitman. During operation, material is compressed and crushed between these two plates. Both plates experience wear, but the swing jaw plate often wears faster near the discharge end due to the crushing motion.
How do I choose between Mn13, Mn18, and Mn22 jaw crusher plates?
The choice depends on the hardness and abrasiveness of the feed material. Mn14 is commonly used for recycling applications and softer materials. Mn18 is the most widely used grade for quarrying and aggregate production. Mn22 offers higher wear resistance and is recommended for highly abrasive rocks and mining applications.
When should I use TiC reinforced jaw crusher plates?
TiC reinforced jaw plates are recommended when crushing extremely abrasive materials where standard manganese steel wears too quickly. The titanium carbide inserts significantly increase wear resistance and extend service life in demanding mining or hard rock applications.
Can jaw crusher plates be flipped to extend wear life?
Yes. Many jaw crusher plates are designed to be flipped 180 degrees once one side becomes worn. This exposes a new crushing surface and helps maximize the total wear life of the plates. However, plates should always be inspected for cracks or damage before flipping.
What is CSS (closed-side setting) in a jaw crusher?
CSS, or closed-side setting, refers to the smallest gap between the fixed jaw plate and the swing jaw plate during the crushing cycle. It determines the final product size and affects crusher capacity, wear rate and overall performance.
What information is required to quote jaw crusher plates?
To quote replacement jaw crusher plates, the following information is typically required: crusher brand and model, part number if available, feed material type, and operating conditions. Drawings or worn plate samples can also help ensure accurate manufacturing.
Which jaw crusher brands are compatible with MINEVANT jaw plates?
MINEVANT jaw crusher plates are compatible with many major crusher brands including Metso, Sandvik, Terex Finlay, Kleemann, McCloskey, Komatsu and others.
