O1 steel japan sword?

Hi all,

 

I would like to find, worthy O1 steel from japan tanto, wakizashi, to katana prepare? :rolleyes: I know it the hamon a line will not be visible on him. Or after? :blink: I read one topic, from the broken heat treat method ( water 3 seconds, next in oil ). How let me make heat treatment differentiated between on this steel, to the achievement of the suitable endurance of the back? :huh: S.O.S please!

 

Regards,

 

Zoltan

i would very much NOT suggest a water quench of any sort with O1

I think it's alright for tantos, but wouldn't the chromium content make it a tad brittle for anything larger?

I had a strange thought the other day.

If I were locked in a room with a copy of myself, i wouldn't like me very much.

you can quench O1 in water, just about, but you'll lose 2 out of three blades. it's about the only way to get it to show a decent hamon though. clay on the back and an oil quench will give you differential hardening, but mostly because the clay acts as enough of a heat sink to stop the spine transforming in the first place.

 

but i agree, O1 isn't really suitible for swords, and i wouldn't water quench anything of O1 over about 7"

this is one posted by mushisushi last year, which was normalised 3 times and water quenched. but really, there's no substitute for plain carbon steel, except tamahagane.

Zoltan, you are only going to get so much toughness from O1 because of it's high carbon content, which I believe is close to 1%. It will give great wear resistance but will tend to be brittle. I'd look for a steel with a 0.5-0.6% carbon content to make a sword from.

Zoltan,

 

Last I knew you could get a steel from Germany that was a W2 equivalent. I bought some from Dr. Batson a couple of years ago here in the States. Hopefuly, this will give you a direction to start looking in. This is what he told me about it.

 

The steel is Thyssen Thyodur 2833. It is a German made w-2 steel with from

.95 to 1.10 % carbon and with .25 % vanadium.
