In these cases, the heat treatment is applied after CNC machining, as high hardness reduces the machinability of a material. For example, this is standard practice when CNC machining tool steel parts. What are common heat treatments for CNC materials? Annealing, stress relieving & tempering ...
The resultant mix is iron ore or 'cast iron' but it is quite brittle. Ah, now to make it into steel, we have to reduce the phosphorus and sulfur content AND the carbon content... this is done by adding certain ingredients such as, I believe, aluminum to make the 'iron' more mallea...
The steel is then closely monitored as it cools to ensure that the integrity of the microstructures is maintained. Additional processes, like hot dip galvanizing, can be applied to further protect the steel. Welding steel beams Different types of steel beams can also be assembled by welding ...
