i'm forming high grades carbon steel pipes into bends ( elbows) using induction hot coils , i don't know how to maintain the yield and tensile strenght because everytime after bending the test result of the bent area illustrate lower grade. any suggestions???

You've got a bit of a problem.

Let's say you were using 0.30% carbon tubing that was heat treated to a certain tensile and yield strength. In order for the original tubing to be hardened, it had to be heated to the austenitic temperature
