Carburizing 316 SS

I need info on carburizing 316 ss. I am working on a project that requires a ring of 316SS to be hard enough to bite into annealed stainless steel tubing. Strain hardened 316 SS bar material is not quite hard enough to do the job. I know that some companies do this to their product, but I cannot find info on how to do the process.

I would investigate the Kolsterising process from Bodycote. It is a diffusion hardening technique that provides higher hardness and enhanced wear resistance without severely degrading the corrosion resistance, which is a problem when carburizing stainless steel.
