effects of chlorine on quench of mild steel?

i'm sorry, i should have stated that this is not for a knife, it's a safe that i constructed for a friend that will be case hardened and quenched b/c it's fairly soft now, especially the seams that i welded and the only way i can think of to do it is to quench it in my pool but i wasnt sure what effect if any the chlorine would have, and i figured someone here probably would
 
To the best of my knowledge, the water should be clean.
The chlorine in the pool is however very dilluted. I do not know if this would affect it though.
Lets hope Mete wanders over to your thread, he is the boffin in this department. :D Have you tried a search on the net?

As far as I remember, you don't have to quench something you're casehardening.
If you're using kasenite, you either apply the stuff and then heat the material up, or heat the item to cherry red and then brush on the kasenite. It tells you on the can. You just let it cool on its own.

If you're thinking that you can caseharden mild steel on its own by heating and quenching, I don't think it will work.
 
I agree, it will not work. Mild steel does not have enuf carbon, which you all know is essential for hardening in steel. The way we used to do it was to pack the ms in good old coal and then put the whole package in the furnace overnight. The coal gives off carbon when heated sufficiently and the steel takes it in. We would just leave it to cool off in the coal after removing it from the furnace. It was not 100% even hardening though.
The more modern way is to dunk it into a red hot solution that is high in carbon. Probably some other ways too.

i'm using carburizing powder b/c it's what i have at school and for that u just get it really hot with it packed around it and let it "soak" then i've simply found that it works better to quench it afterwards, and yes i did try to find this on the search but for some reason it doesnt like my comp, mete where are you? i need your masterful advice :D
 
also if u look up "carburizing pack" you'll notice that quite a few of the pages tell you to quench afterwards, and the whole purpose of case hardening is to give the skin that extra carbon that the rest lacks
