Nitriding 316 Stainless Steel?
Nitriding 316 Stainless Steel?
(OP)
Hello all,
Is nitriding austenitic stainless steels a common process? Normally we make a part made from 410 stainless that has a #3 drill point on it, and we quench and temper to give us a case hardness of around 50 HRc. In addition, it is meant to drill into 18 gauge sheet steel. Ideally we would like to use 316 stainless for the improved corrosion resistance over 410. Are there any complications with nitriding 316, and will this process effectively decrease the corrosion resistant properties of 316? It has been suggested that we look into Bodycote's 'Kolsterising', but I know that nitriding will be much cheaper and may offer the same desired outcome. Any thoughts on this would be great, thank you.

1. The core hardness will be that of annealed 316
2. The surface hardness will not be all that great, except for a very thin layer.
3. you need to use one of the ion implantation methods that is done at low enough temperatures to completely avoid the formation of carbides or nitrides, otherwise your corrosion resistance will not be any better.
What level of corrosion resistance/hardness do you need?
Have you considered H23? With high Cr and W and low C it has pretty good corrosion resistance.

or full harden and temper the heads.
It needs equipment that passes the parts oriented through the HT process.
Not hard, bowl feeders, alignment tabs, grippers and induction coils..
