Mechanical properties from chemical composition
Mechanical properties from chemical composition
(OP)
Is it possible to obtain mechanical properties (yield point, resistance, elongation, etc), or some of them, even approximately, by knowing the chemical composition of a steel plate?
In this case it is a very low carbon steel, used to build a galvanizing pot, and its compositions is(%):
0.04C + 0.28Mn + 0.019P + 0.008S + 0.063Al
I don't need a very accurate value. The steel supplier is unknown.
Thanks in advance,
Heyner

RE: Mechanical properties from chemical composition
Your reported chemical composition indicates a low carbon steel. The Al addition implies a killed steel (deoxidized). At my present location, the only information I can find regarding this low carbon steel is as follows;
Assuming a 1006 CS, hot rolled;
UTS ~ 60 ksi
Yield Point - ~40 ksi
Elongation (2" gage) ~ 30%
These are ball park estimates.

Min. tensile strength, kgf/mm2 = 20 + 100(%C)
in your case, it's approx. 34 ksi. This should be the figure to be considered in your design.
Besides, from safety pont of view, usage of an unknown steel, should comply the following;
- it does not subject to temp. more than 350 C
- do not weld it
