I have an application in which I need to take a piece of C 1045 Hot Rolled. 3/4" diameter (Rockwell of C16 from the chart) or 3/4" diameter C 1045 Cold Drawn. (Rockwell of C15 from the chart) and heat it red with a torch to bend it around a fixture to obtain a 4-1/4" radius and then let it cool ,then and after it cools stitch weld it at the bottom every 18-24" to a piece of 3/4 " thick flat plate of steel to hold it in place.
My question is if I use the C 1045 H.R. in this application, will I lose the hardness of the material (C16) when I heat it since it was hot worked anyway when it was manufactured?
If I use the C 1045 C.D. (C15) steel in the same application will its' hardness be changed any differently beacuse it was cold drawn during its manufacture?
I want to end up with the highest hardness value when finished and I am not sure which would be best in this application.
