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.
