: Whatīs best hardness treatment for 8620 Steel?
: Itīs for a 16mm shaft that will work with a one-way bearing on it. 15N*m torque in the shaft.
: Bearing specification says 58 Rockwell C minimum.
: Thanks All!

JP.. I would suggest another material other than 8620- your only going to be able to surface harden this material. The process can be various methods -flame vs. induction or even pack in carbon produce in an oven. Allow for grinding post harden - it will grow a few tenths of a thou.I would also have it centerless ground.
Good luck.
