DIN2391 standard steel and 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.
