Dear Readers
I have bent Carbon Steel (A179) (2.11 mm Thickness) tube and there is requirement for post bending stress relief due to Sulfide stress cracking. based on UCS-56 the minimum soaking time at maximum temp. is 15 minutes, bu at UCS-79 it is mentioned that it is possible to change soaking time for less than 6 mm thickness if it is sure that all thickness is in the same temperature. so I want to know what is the soaking time for u-bend of carbon steel tube with 2.11 mm thickness? 15 minutes or lesser?
------
besides i have the same question for solution annealing of Stainless Steel (SS316 and SS321) tubes with the same thickness. How much soaking time is enough for Solution Annealing of these tubes?
