Help me choose steel....please...
(OP)
Hi. I am searching for a low-carbon steel that will allow me to do the following. First, the dimensions of the steel bar I will be using are 1/4" by 1/4" by 48". I will be welding this bar to other pieces of steel, painting it, and then baking it in an oven at 500 degrees F for 15 minutes. I need to bake it two times to allow paint to cure. The problem I have experienced is that the steel tends deform. There are shear strains, which are causing bending and twisting of the steel bar. Could someone please recommend a steel that would stay straight through my process? Thank you very much.

Weld the assembly together,and then Anneal it to remove residual stress due to welding and forming. Then try your coating process. Fix your pieces so as not to induce stresses during bake.
Use as low of a heat input as possible to weld.

Thank you.

Assuming you may not heat treat the bar (and straighten it) before any other operation, I suppose (but no direct experience, only thoughts!) that an austenitic material (stainless steel) would behave better as it is less prone to hardening, softer and better resisting to temperature (however the heat expansion coefficient is higher and that makes worse).
