What the perm is coming to you.
and how hard you work the material.
If the bar is well annealed to start with (<1.02) the it sounds doable.

You may want to consider sending samples out to a magnetic testing house from time to time.

PS
You have helped me tremendously. I have eccommende this forum to my clients and the PMPA.

This temperature will work but may be a little high, so if someone has a properties data sheet would jump in with a clarification.

It is possible that due to the materials thermomechanical history it is slightly ferromangetic. This could be due to retained delta ferrite or some strain induced matrensite. If this is the case then you may be magnetising the material by the way that you handle it.
We manufacture cold finihsed tubing all of the time that has magnetic permiablity above 5, but it must be demagnetised to a specified residual field level.
It is also possible that you have material that is very lean on Ni (to save money) and therefore not real stable. It could be that your machining is working the surface layer enough to make it profoundly magnetic. I doubt this, 303 machines well enough that you shouldn't impart much work.
If the bar is non-ferromagnetic to start with you sould be able to manufacture non-ferromagnetic parts.
