Straight Spring Help
Straight Spring Help
(OP)
I am moving this thread to this forum, I didnt see it before.
Hello all, I am trying to find if a material exists in this state.
I am looking for a Stainless steel wire (.078-.08")that has spring properties.
I have ordered 303/304 stainless wire with spring temper, but it doesn't seem strong until you cold work it into a shape, coil etc..
I have ordered some music wire (spring steel), but Im sure it will have the same outcome.
I need the wire to be a strong spring while it is straight, it doesn't need to be formed into anything.I prefer stainless.
Anyone have a clue where I can get this material, or do you know if there is a way to heat treat it into this state?
Thanks

If I look for 304 1/2 hard wire or 302 3/4-full hard wire. Am i to assume this is a spring temper? and the material isn't just hard? Do I need to be looking for the parameter ASTM A666?
I checked the net for a minute and I dont see anything in wire like this, the only one I found that was exactly this was in a coil and it needs to be straight.

It doesnt mention anything about spring temper... Is that assumed or is this wrong thing?
Thanks

Can you explain exactly what it is you are trying to do, a straight piece of wire will not make a very good spring.

Can you provide a sketch with dimensions and some pictures, I can of follow but there a lot of information that you can clearly see but I can't.

It was hard but formable, as any music wire should be, and did not rely on my cold forming for the hardness.
It's a clever design, but will be sensitive to edge radius of the swinging door, and probably high wear of those corners and the mating surface, if that's an issue. If you want it stiffer, the easiest way might be to make the door thicker, at least at the hinge end.
This would probably be a good time to analyze some parts for stress, in particular the complex bending of the hinge pin and its contact areas on the stationary portion, which gets interesting when you start allowing the hinge pin 'beam' to deflect angularly, as it must. I suspect you will find that even the best music wire will not be adequate, which is probably why more typical designs separate the centering spring function from the hinge pin.
Have fun with it, and good luck.
