Abstract

PURPOSE:Steel pipe (weld) at 700 deg.C or higher having been annealed after being manufactured to pipe is force-cooled, in succession to the annealing, at a specific cooling rate to the predetermined temperature of a limited range and is furhter annealed, whereby its yield strength and toughness are improved.
