I have no experience machining stainless steel and I need to make a small part from stainless that will be as high strength (tensile) as possible, with high hardness and a very smooth finish. I searched on-line and have settled on 440. I intend to machine the annealed form, then harden, then polish. (make sense?) I read that 400F is easier to machine than 440C, yet the calculator gives me the same speeds/feeds for 440C (annealed) and 440F (annealed). Does this make sense? I would have thought that the “easier to machine” alloy would have higher feeds/speeds?
