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.
