Case Hardening Experiments Mod-Up

<< < (14/19) > >>

PekkaNF:
Can't locate here any Kasenit or such, but today in one local forum someone was sellig Potassium Ferrocyanide powder 5€/100g and remenbered this thread. Is this yellow powder as itself any good if I need to case harden small parts?

How are other experiments doing?

Pekka

drmico60:
Hi Pekka,
If you mix the potassium ferrocyanide with powdered charcoal and sodium chloride (common salt) this will work in the same way as Kasenit. I think I used a mix with equal parts of each component and it worked OK.
I hope this helps

I think you are missing the important variable in the sugar coated hardening experiment. Time.

All the anecdotes would indicate that the diffusion of carbon into the steel is not that rapid. Only heating for three minutes is probably not nearly enough time.

Mark, I did what was claimed for a sugar case hardening method. Do you have a reference for the anecdotes you mention which specifically use sugar to case harden steel over a longer period?

I can tell you that diffusion of carbon into steel can happen considerably faster than 3 minutes.

It happens in seconds with Kasenit, for a thin case.

RotarySMP:
I was referring back to Andrew and Normans posts on page one.
