drawing out ...

I imagine it means reducing the temper to make ss steel easier to work with.

What is the process to do this?

Am going to try to make bolsters from 303 ss if I can find some, or any ss I can get. Maybe I can make pins for the bolsters from the same stock.

Thanks, Charlie

Charlie,

303 can be used for bolsters but it seems that most makers prefer 416 stainless. Pin stock is available and if you ever decide to have the bolsters engraved, 416 SS is prefered.

Drawing out ....the temper is part of the heat treating process. Steel is taken to critical temp. (non-magnetic) and then quenched in the proper medium (usually oil or air). This hardens the steel but leaves it brittle. The steel is then tempered (I beleive this is drawing the steel, I could be wrong) in an oven (between 350 - 900 deg depending on the steel and Rc required. Now a days many maker also throw in a cryo treatment ( this helps in the grain transformation from austintite to martinsite)

This is cover by people way more knowledgeable than me in the forums. Do a search for heat treating, you'll find all kind of information.

I hope this helps, and if I'm wrong guys, please let me know.
Ya gotta learn some how.

It depends on who you are talking to and what the topic is.

There is drawing the temper (tempering) which means to temper the blade as described above.

If you are talking to a person that forges, drawing out means to stretch the steel into a longer piece by hammering on it.

Thanks guys, you sure are a helpful bunch in here.

Yah, I was talking about drawing temper, I guess. Is it necessary to do this to ss for bolsters, or can it be worked as is? Thought it might be too hard to work with...

Thanks again, and I will get some pin stock for the bolsters, now that I know to.

Charlie

Charlie,

416 and 303 can be worked as is. 303 can't be heat treated. 416 can be heat treated and the tempered to a lower RC (there have been discussions on this in earlier threads) Maybe you could do a search on 416 with the search feature!

Good Luck,

Bob Sigmon
