How do you choose the right slewing bearing material? Which one suits you better, 50Mn or 42CrMo?
50Mn is a medium carbon steel with good toughness, ideal for light industrial equipment with medium to low load requirements. On the other hand, 42CrMo is a low alloy steel that contains chromium (Cr) and molybdenum (Mo), making it harder and more wear-resistant. It's perfect for high-load applications, such as heavy-duty cranes in engineering machinery.
So, how can you tell these materials apart? It's simple! 42CrMo has a brighter surface with higher luster and better corrosion resistance, making it less prone to rust. In contrast, 50Mn appears duller and rusts more easily. With a grinding wheel, 42CrMo sparks less with a darker spark color, while 50Mn produces more sparks, with more branching and a brighter color.
