Metal Properties Database

I'm working with FEA and i need the stress-strain graphics of the AISI Type A2 Tool Steel, but i can´t find it anywhere. Does anybody know of some database available on internet that could help me?

Thanks
Guilherme

I've briefly gone through the net for the properties of AISI A2, they don't really have the stress-strain graph... but they do show it's youngs modulus and etc and in these links below... hope it might help...

Guilherme,

You don't intend to deform the A2 plastically do you? If not, then can't you choose to model the A2 part as elastic only, and use the Young's modulus as your only required parameter?

Cory

Thanks for the links Salvatio, i found one stress-strain graphic on the net. It´s not a very good one, but I think it´ll do it.

Yes, I do intend to deform it plastically... and a lot. It´s not very usual to do it with this kind of material, but I´m simulating the forging process of a cylinder that´ll be used in steel plates rolling. So it´s very difficult to find all the data I need.

Thanks again

Guilherme

overgone-

so your starting with annealed material right? You might be able to make a compression specimen and have your local metallurgy/mat. sci. school do a test and output the data in ASCII form for your FEA package. I'm not sure but I'd bet a dollar that the compressive curve is different from the tension.

overgone,

I would recommend you discuss this with a manufacturer of A2 tool steel like Carpenter, Crucible, or Timken Latrobe. They will have mechanical property data on this alloy, and not just room temperature data, which will not be of much use to you. Also, as NickE pointed out, a tensile stress-strain curve is not really what you need. You want flow stress curves, probably for a variety of temperatures and strain-rates. Tool steels have poor elongation in tension, so try to keep the deformation compressive as much as possible. Hydrostatic stresses are your friend. The following links provide more information on the steelmakers I mentioned:
