+C Hard. No final treatment after final cold drawing.
+LC Soft. Final heat treatment is followed by a suitable drawing pass (limited reduction of area).
+SR Stress Relieved. After final cold drawing, the tubes are stress relieved in a controlled atmosphere.

The cold drawn welded tube is produced by drawing ERW (electric resistance welded tube) through a die and over a mandrel plug. During this process the sizing (wall thickness, inside and outside diameter), as well as weld integrity and surface finish is closely controlled to produce tube of the required size and mechanical property characteristics.
