SAE 1020 and SAE 1008 material properties and stress/strain curve
(OP)
Hello,
Does anyone have the material properties for SAE 1020 and SAE 1008 steel or can point me to a good web site for these properties? But I also need the true stress and true strain curves for them too. Thanks.

It costs ~ $100/specimen to tensile test at an A2LA accredited lab. The output can be true stress-true strain if you ask for the data to be collected.

True Strain = ln(1+ engineering strain (At very low strain there is little difference)
True Stress = Engineering Stress * (1 + True Strain)
If you plot the results on a log/log graph you should obtain a straight line.
The slope of this line 'n' would be the work hardening exponent and the intercept on the y axis is 'K' the strength coefficient.
If you are interested in looking at formability and you are carrying out tensile tests then you should be able to determine 'n' quite easily.
It may also help to look a the 'r' value which is a measure of anisotropy and is influenced by a material rolling history.
