Do you know the features of stainless steel machining?

The machinability of stainless steel is much even worse than carbon metal machined components. The machinability of austenitic stainless steels is the worst. Stainless steel trimming has the pursuing characteristics:
(1) hardening very seriously in processing: because the plasticity of stainless steel is quite heavy, and not stable enough, under the action of processing stress, the hardening layer produced. And impact the plan of the next
