yield point for tinplate - can stock materials 2

[dwremote]

I'm looking for a chart or something similar to provide basic information for operators of straightening machines. The materials processed are typically between .005" to .02" thick in tempers associated with can making. I suspect this is generally known information, but I have no idea where to find it quickly. Specifically, as an example, if I have tinplate in T5 temper range and .007" thick, how much penetration is needed to reach yield if I'm bending it with rolls 1.5" in diameter on 1.625" centers?

Apparently this is high production equipment that does not lend itself to test parts or sampling. Can you access a hand operated roll bending machine or just clamp two rolls on a bench or plate and measure the penetration of the third roll?

Go to asminternational.org and look up tinplate. If it will not let you into it deep enough to answer your question, give us a road map of how far you got and one of us with a subscription can probably ferret it out.

Also I will try to remember to look it up in my metalforming book at work.

NickE,
Excellent resource material. I had no idea such helpful info is available. Therefore I took the liberty of creating a FAQ by copying and pasting the links that you provided. I trust this does not qualify as plagerism. I suggested a new category of forming/straightening.

WOW! Thanks metman, I am flattered.
