Does anyone have any experience on using torsion springs in the reverse direction. I know that it is not adviseable to do so, but are there any rules / formulas that apply to this type of operation?
Thanks, Jack
If a steel spring (1080) comes in contact with 2024 aluminum will galvanic corrosion initiate (clean environment)? Would a zinc plating help minimize the risk.
Thanks Jack
Is it possible to perform Chromate Passivation by using Trivalent Cr process without depositing any Hex Chrome?
If not, is the amount of Hex Cr typically acceptable for the limits imposed by the RoHS?
And what are people in this country doing about this issue?

All,
I am confused, is it necessary to bake stainless steel parts that have been pickled and passivated? No one seems to be doing it. I'm specifically talking about sheet or wire that has been transformed by cold working into martensite, like full hard (40% red.) 302 SS or 17-7PH in the CH900...
I am looking for information showing the advantages and disadvantages of heat setting compression springs for automotive application. Free length of 1.25" and Diameter of about 0.20" Chrome Silicon.

It is commonly known in the spring industry that when 302SS springs are stress releived after coiling, they increase in diameter (d) and decrease in free length (Lf); conversely, music wire decreases in diameter and increases in free length.
My question is why? I suspect that it has something to...
How would one go about calculating the free length tolerance on the following spring?
d = .016"
OD = .292"
Lf = 1.2"
Ntotal = 20
Material = Phos. Bronze
Standard equations I have seen come out with tol. bigger than the free length! Are there any equations that practically take into account...
I am trying to design a stranded wire torsion spring. Is there any information available that can be used to calculate forces and safe operating stress levels for a spring of this type?
