In industrial sectors such as mining, crushing, and grinding, casting pallets are critical for both load-bearing and impact resistance. Pallets made from low-quality steel risk rapid deformation or fracture under high-impact loads. Therefore, impact resistance is a decisive factor in material selection.

Manganese Steel and High Impact Resistance

Manganese steel (Hadfield steel) is widely used in applications requiring high impact and wear resistance. Containing approximately 12–14% manganese (Mn), it hardens upon impact while retaining internal toughness. This provides:

  1. Impact Energy Absorption: Manganese steel absorbs impact energy, preventing fractures.

  2. Work Hardening: The surface hardens under impact or abrasion while the core remains ductile.

  3. Long Service Life: High resistance to wear and impact reduces maintenance costs.

Choice of Casting Pallet

For high-impact resistance, casting pallets made of high-manganese steel are preferred. Advantages:

  • Can be cast into complex shapes.

  • Offers high resistance to both impact and wear.

  • Ideal for mining crushers, quarries, and heavy industrial machinery.

Conclusion

Using manganese steel in high-impact casting pallets is essential for durability and longevity. Standard carbon steels fail under repeated impact, whereas manganese steel provides superior impact and wear resistance thanks to its work-hardening properties.
