Best Way to Harden Nitronic
Best Way to Harden Nitronic
(OP)
hi there,
how is everyone? I just found the forum, get site!
heres my question,
We have an order to machine a part from Nitronic 50 and further harden them. What is the best way to cold work the steel? It must not deform aesthetically and improve yield strength and corrossion resistance. Im looking at Kolstering. Are there better options out there? Thank you.

But you must take care that any process is at low enough temp that you don't form any Cr carbides in the material. This will seriously reduce corrosion resistance.
Are the parts from bar or sheet? If so try to get cold worked material to start with. It will machine fine.
Your customer should be dictating the hardening process and resulting properties. This should not be guess work.

I would go with liquid nitriding.
RE: Best Way to Harden Nitronic
Since nitrogen ions are made available by ionization, differently from gas or salt bath, plasma nitriding efficiency does not depend on the temperature. Plasma nitriding can thus be performed in a broad temperature range, from 260°C to more than 600°C. For instance, at moderate temperatures (like 420°C), stainless steels can be nitrided without the formation of chromium nitride precipitates and hence maintaining their corrosion resistance properties.
