DIN 2391-2: 1994 / Seamless precision steel tubes - Part 2: Technical delivery conditions

Heat Treatments

  • Cold finished (hard) (BK): Tubes do not undergo heat treatment following the final cold forming and, thus, have a rather high resistance to deformation; Cold finished (soft) (BKW): The final heat treatment is followed by cold drawing involving limited deformation. Appropriate further processing allows a certain degree of cold forming (e.g. bending, expanding); Cold finished and stress-relieved (BKS): Heat treatment is applied following the last cold forming process. Subject to appropriate processing conditions, the increase in the residual stresses involved enables both forming and machining to a certain degree; Annealed (GBK): The last cold forming process is followed by annealing in a controlled atmosphere; Normalized (NBK): The last cold forming process is followed by annealing above the upper transformation point in a controlled atmosphere.
  • Normalized: 910 to 940°C, afer reaching the temperature at total cross sectional, cooling in static air; Stress relieving: 530 to 580°C, holding period for wall thickness up to 15mm at least 15min and for 15 to 30mm at least 30min, cooling in static air; Annealing(enamelling): 800 to 885°C; Cold forming at 580°C; Hot forming at 1050°C.
