Re Heat Treatment of Stainless Steel Forging
(OP)
In reference to thread367-195557: the affect of doing the Heat treatment twice
For a petro-chemical project, we have the following Heat Treatment requirement. Tempering at 740 Deg C for ASTM A182 F11 Class 1 material. However, the material available in market is Tempered at 620 Deg C which is the basic ASTM requirement. Can Re heat treatment(Normalizing and then Tempering at 740 Deg C) be considered a solution ? Will this re-heat treatment change the physical properties of material beyond the requirement ?

Get coupons of the material heat treated to the 620 temper and re-temper them at 740 and test them.
They should come out exactly as you expect.
