UCS-79(d)(5) warm forming?
UCS-79(d)(5) warm forming?
(OP)
Why does UCS-79(d)(5) exist? Or rather, why is forming in that temperature range a problem?
Is this called "warm forming" in this temperature range? I've never heard that term until today when I started researching this.

Residual tensile forming strains can result in reduced corrosion resistance and possible low temperature creep.

So how is warm forming worse than cold forming? I understand that it takes less force to warm form and that the warm temperature isn't hot enough to relieve residual stresses. I just don't see how cold forming is better than warm forming as this rule implies.

Perhaps since the yield stress is lower in the warm forming temperature range that the strain pattern is different in a way that raises concern.

and it is still cold forming.
