First, since your question is not very clear, I will do my best to explain. First, whether all steels are magnetic depends on whether their composition includes carbon. If it contains carbon, then it will be magnetic; if it does not contain carbon, then it will not be magnetic. Therefore, nonferrous metals are naturally nonmagnetic, whereas ferrous metals are magnetic. Therefore, to select linear motion products that are non-magnetic, non-ferrous metals must be used. Therefore, we often use stainless steels that do not contain carbon. However, the problem is that nonferrous metals (i.e., metals that do not contain carbon) cannot be heat-treated, and therefore have relatively low strength. To ensure durability under heavy loads, we must address this challenge by employing a variety of engineering techniques and material selections when choosing guide rails, bearings, and components in friction-prone areas. I’ve provided a brief explanation, hoping it clarifies your questions. If you have any other questions, please feel free to ask—I’ll do my best to answer them based on my knowledge. Thank you.
