Delivery Condition

Heat treatment process

+C

Cold drawn/hard.After the last cold forming,no heat treatment.

+LC

Cold drawn/soft.After the last heat treatment follows the cold drawing there is a light finishing pass.

+SR

Cold drawn and stress relieved annealed. After the final cold drawing process the tubes are stress relieved annealed in a controlled atmosphere.

+A

After the final cold drawing process the tubes are stress relieved annealed in a controlled atmosphere.

+N

Normalized. After the last cold drawing process the tubes are annealed in a controlled atmosphere.
