Conditionnement thermique / condition de livraison

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