Looking for material porperties on AR-200?
(OP)
I have a mill run in my hand for AR-200 sheet metal but I need a few more paramters then what is on the mill run. I cant find AR200 on matweb so I assume it is just a common trade name. Can anyone offer me an actual code for this product?
Thanks a bunch.

I should have guessed that was the answer and its not even monday today... I guess I will need another excuse.

We just got a new accupress press brake and I am just adding all the materials we use to its software. There are a few parameters that I am unclear about. Perhaps you could enlighten me.
The program asks for the following(with no units) along with the data that was already entered from factory for A36
Strain hard - 0.17
Strength - 676
PreStrain - 0
Yield Stress - 242
Youngs Modulus - 200000
Poisons Ratio - 0.3
Fracture strain - 0.24
Coulombs - 0.1
UTS - 500
So my question would be what measurement is being used to give a hardness < 1,
what is "strength"?
Is fracture strain a % elongation at failure,
What do Coulombs have to do with press braking?
RE: Looking for material porperties on AR-200?
Strength is the Ultimate Tensile Strength.
Fracture strain εf is the non-dimensional value of strain at fracture. Percent elongation is a commonly used substitute, except that it is 100 · εf .
Coulomb is referring to Coulomb's law for friction.

However, I dont think Strength is Ultimate Tensile Strength as there is a UTS parameter. I do think that strength would be the fracture point assuming constant volume in the yield section of the curve.
Im still trying to figure out how to get this true strength as well as the strain hardening exponent n.

So if the K and the n are both experimentally determined how can I find them? I have yet to see AR200 in any lists for k and n values. Maybe im way off the mark on this one and you can calculate them somehow.

They both should be higher should they not?
I dont have the capabilities of running a strength test on material?
