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.
