Heat treatment process delivery conditions:
Delivery Condition	Heat Treatment Process
+C	Cold drawn / hard. After the final cold forming no heat treatment.
+LC	Cold drawn/soft. After the final heat treatment-limiting deformation, cold drawn, allowing a degree of cold deformation
+SR	Steel heat treatment is applied after the last cold deformation process, the result of state steel after due process, the residual stress deformation and machining makes a certain degree of difficulty increases.
+A	In the final step of the steel pipe after cold deformation, placed in a controlled atmosphere furnace for annealing.
+N	In the final step of the steel pipe after cold deformation, placed in a controlled atmosphere furnace at a temperature above the phase transition point to continue annealing.
