EdStainless You applyed the BN in a past form, on the small parts that we use I was thinking that perhaps we can apply it as a light powder and do a DI water clean. Comments please

What type of SS are you using, most bearings that I have used are 440c ss, very magnetic.

rorschach You are correct about the oil becoming carbon, I would use a mild detergent. The small parts are to soft after anneal to tumble they distort. Regards

Thanks to all for your interest and feed pack, I will try and address your response questions. To metengr I use a continuous, bright anneal heat treatment furnace @ 1850f the time each basket is in the heat zone is 5.33 min this is the min time to yield the correct hardness Vickers of 135hv + /...

metengr is correct, If you are annealing the 321ss in a vacuun furnace you may want to try using Argon as a quench gas.

mcquire, Thanks for the feed back, I have tried hundreds of buffer materials the problum with them is that they remain on the base material even after a ultrasonic clean. I run LPC and SEM and show a small level of particals remainimg that will effect the parts performance I refer to them as...

Here’s a problem that has puzzled me for years, I heat treat 305 series stainless steel the parts are quite small approx 0.2500 squares x 0.017 thick, my problem is that they stick (fuse) to each other. I use a temperature of 1850f and a hydrogen atmosphere (9999% pure) the same problem...
