Photo: Mellott Company. When choosing manganese wear parts, there are three key considerations to make. 1. The material being crushed. Is the rock hard (i.e., granite) or soft (i.e., limestone, sandstone)? What size is it being crushed to? How has material been prepped? If material is being recycled, is tramp metal included? 2.

High manganese steel typically contains around 11% to 15% manganese, which is significantly higher than traditional steel. The high manganese content creates austenitic crystals during solidification, resulting in work-hardening ability – a unique characteristic of this material. Additionally, the presence of carbon further enhances the ...
