Heat Treatments

  • Welded and sized (BKM) - Bright drawn, no heat treatment after welding and sizing; Annealed (GBK) - After sizing, the tubes are annealed in a controlled atmosphere or under vacuum; Normalized (NBK) - The tubes are heat treated above the upper transformation point in a controlled atmosphere or under vacuum.
