Manganese eighteen chromium secondary lining plate is stronger and more durable, with a significantly increased crushing efficiency

In the long front line of mining crushing production, lining plates are the key armor that guards the core of equipment and determines production efficiency. Faced with harsh working conditions and continuous impact, the choice of materials directly affects the continuity and overall cost of production. Our factory has been deeply involved in the field of mining accessories for forty years, and we are well aware of the weight of every detail. Today, we will compare two mainstream high manganese steel liners: Mn18Cr2 and Mn13Cr2, to help you make a more visionary choice.

Comparison of core advantages: the essential leap of resilience

Mn13Cr2, as an excellent representative of traditional high manganese steel, has stood the test of time under moderate impact conditions due to its good toughness and work hardening ability. It can harden on the surface during impact, resist wear, and is a reliable choice in many scenarios.

However, when faced with extreme working conditions such as extremely high stress, strong impact, and complex abrasive wear, Mn18Cr2 material achieved a significant leap in performance. The key lies in the higher ratio of manganese and chromium elements, which brings about essential strengthening:

More outstanding work hardening potential: Under severe impact, its surface can form a harder and more stable hardened layer, while its inner toughness remains extremely high, and its ability to resist fatigue cracking is even better.

Better wear resistance: The hardened layer is more wear-resistant, and when crushing high hardness materials, it can maintain the contour of the lining plate for a longer period of time, stabilize the discharge particle size, and ensure sustained high production.

Stronger overall load-bearing capacity: From initial hardness to comprehensive performance during use, it provides a stronger protective barrier for the core rotating components of the equipment, especially suitable for large and efficient crushers.

The way of choice: Adapt to the working conditions to maximize value

Choice is not a simple 'substitution', but a precise 'matching':

If your working conditions are relatively stable and the impact load is moderate, Mn13Cr2 lining plate, with its mature technology and cost-effectiveness, is still a solid economic and practical backing.

If you are pursuing maximum productivity and facing the challenges of high material hardness, severe impact, and high downtime costs, Mn18Cr2 lining plate is the answer for the future. It means longer replacement cycles, more stable production capacity output, and lower ton consumption costs, bringing long-term operational benefits that far exceed the difference in initial investment.
