BK ( C) Cold completed/tough (chilly finished as drawn).
No warmth treatment following very last chilly forming procedure.
BKW ( LC) Cold finished/soft (evenly cold labored).
Following previous heat remedy there is a gentle finishing move (chilly drawing).
BKS ( SR) Chilly finished/tension alleviate annealed.
Right after the closing cold forming method the tubes are anxiety alleviate annealed.
GBK ( A) Annealed.
Soon after the closing cold forming process the tubes are annealed in a controlled ambiance.
NBK ( N) Normalized.
After the final chilly forming approach the tubes are annealed over the higher transformation stage in a controlled atmosphere.
Exams: all tubes are checked in accordance to the relevant production stXiHu (West EPT) Dis.Hu (West EPT) Dis.rdsupplementary/optional checks are obtainable on request chemical mechanical and technological exams are created in accordance to related stXiHu (West EPT) Dis.Hu (West EPT) Dis.rd
