Products Description
Mn13Cr2 High Manganese Steel Jaw Plate is a wear-resistant cast steel component used in mining, stone processing, and material handling equipment. It is primarily installed in jaw crushers to crush materials through compression and impact. Manufactured from high manganese steel, the product offers good toughness, impact resistance, and work-hardening properties, making it suitable for demanding crushing conditions. During continuous exposure to material compression, impact, and friction, the surface of the jaw plate gradually hardens, improving its wear resistance. Mn13Cr2 High Manganese Steel Jaw Plate is suitable for crushing various hard ores and rocks, helping maintain stable crushing performance and reduce downtime caused by component replacement. Selecting the appropriate jaw plate structure, installation method, and operating conditions helps maximize its wear resistance and meet the long-term operating requirements of industrial crushing equipment.
Product Advantages
Excellent Wear Resistance
The product develops a hardened surface under impact and compression, helping improve its resistance to wear and making it suitable for crushing environments involving continuous material impact.
Outstanding Toughness
The material offers good toughness and can withstand impact loads generated during crushing, helping reduce the risk of brittle failure under normal operating conditions.
Stable and Reliable Structure
The jaw plate features a structure designed for crushing applications and works in conjunction with the crusher mechanism to support normal material compression and crushing operations.
Convenient Maintenance
Proper installation, regular inspections, and timely replacement of worn components help maintain normal equipment operation and reduce maintenance demands caused by abnormal jaw plate wear.
Precautions
Avoid Abnormal Impact
Prevent unsuitable oversized materials and foreign objects from entering the crushing chamber, as abnormal impacts may damage the jaw plate, connection structures, and other crushing components.
Ensure Secure Installation
The jaw plate must be installed in accordance with equipment requirements. Confirm that all connections are secure before operation. If loosening, displacement, or poor contact is detected, correct the problem before restarting the equipment.
Monitor Wear Conditions
During long-term operation, pay attention to wear on the working surface and changes in the jaw plate profile. Excessive wear may reduce crushing performance or place abnormal loads on other equipment components.
Follow Shutdown Procedures
Before inspecting, cleaning, or replacing the jaw plate, shut down the equipment and isolate the relevant power sources in accordance with safety procedures. Confirm that the equipment cannot start unexpectedly before beginning any work.

FAQ
Q: What materials is Mn13Cr2 High Manganese Steel Jaw Plate suitable for crushing?
A: This product is primarily used for crushing ores, rocks, and other materials suitable for jaw crushers. When selecting a jaw plate, consider material hardness, toughness, abrasiveness, and feed conditions to ensure that the material is appropriate for the actual crushing application.
Q: Why does a high manganese steel jaw plate gradually become harder during use?
A: High manganese steel has work-hardening properties. Under the impact and compression generated during crushing, the material surface gradually hardens, improving its wear resistance. However, the degree of work hardening depends on the actual impact conditions and material characteristics.
Q: What should be done if the jaw plate wears unevenly?
A: First, inspect material distribution, equipment operating conditions, jaw plate installation, and load distribution within the crushing chamber. Check for uneven loading, loose connections, or other abnormalities.
