Annealing of Steels – IspatGuruAug 17, 2020 · When low C steels are spheroidized, it is generally to permit severe deformation. For example, when 0.2 % C steel pipe is being produced by cold drawing in two or three passes, a spheroidized structure is achieved if the material is annealed for 0.5 hours to 1 hour at 690 deg C after each pass. The final product has a hardness of about 163 HB.
