Heat treatment:

After welding, all tubes are heat treated at a temperature of 1650℉ (900℃) or higher and followed by cooling in air or in the cooling chamber of a controlled atmosphere furnace.

Cold-Drawn tubes are heat treated after the final cold-draw pass at a temperature of 1200℉(650℃)or higher.
