BK ( C) Cold concluded/challenging (chilly completed as drawn).
No heat therapy right after final cold forming procedure.
BKW ( LC) Cold completed/comfortable (evenly cold worked).
Right after previous heat remedy there is a mild ending go (cold drawing).
BKS ( SR) Cold finished/tension minimize annealed.
Soon after the last cold forming approach the tubes are tension minimize annealed.
GBK ( A) Annealed.
Right after the last cold forming process the tubes are annealed in a controlled ambiance.
NBK ( N) Normalized.
Following the final cold forming method the tubes are annealed previously mentioned the upper transformation level in a managed atmosphere.
Checks: all tubes are checked in accordance to the related creation stXiHu (West EPT) Dis.Hu (West EPT) Dis.rdsupplementary/optional tests are obtainable on request chemical mechanical and technological checks are made according to pertinent stXiHu (West EPT) Dis.Hu (West EPT) Dis.rd
