Does anyone know what kind of steel or alloy is used for the main structural elements in an industrial CNC machine like a Haas VF2 or equivalent. I am interested in building my own machine and I want to know what material to use that will resist rust or be completely rust proof. I know that the main frame is probably cast iron or something but I am specifically talking about the parts that will come in contact with coolant, etc. I have attached a youtube video to help show the material I am looking to identify. It is the material that is under the linear bearings and also comprises the two blocks that hold the ends of the ballscrew.
