I have a need to make some ~6" pieces of 316 wire rod which is say 0.064" for an inch and then around .06" for the next five. The thought was to take .064" wire from McMaster and stretch it on a 10,000N (2000lb) Instron machine which we have down to .061 or .060. It should yield at around 500lbs and only needs to stretch about 11% to get to the desired cross section. My main questions are: can we expect it to stretch evenly and what would be the best way to hold the section of wire you don't want stretched without distorting it. We were pondering making some hardened mini V-jaws. A little bit of distortion is probably OK, or at least if I could have sections of wire of highly controlled diameter to experiment with I could sort out the double diameter part later (e.g. we could manufacture these by centreless grinding perhaps)
I've searched the PM archives and there was quite a, shall we say, lively discussion about straightening music wire back in 2006 but nothing obvious about stretching wire.
