DIN Standard Steel Pipes Specification

German Institute for Standardization (DIN)

DIN (Deutsches Institut für Normung ) standards for topics varying from agriculture to vehicle manufacturing in Germany.

Type:seamless steel pipe:1/2″-24″; ERW steel pipe:1/2″-48″
Condition on delivery:

Term Symbol Explanation
Cold-finished/hard
(cold-finished as-drawn)
BK No heat treatment after the last cold-forming process. The tubes therefore have only low deformability.
Cold-finished/soft
(lightly cold-worked)
BKW After the last heat treatment there is a light finishing pass (cold drawing) With proper subsequent processing, the tube can be cold-formed (e.g. bent, expanded) within certain limits.
Annealed GBK After the final cold-forming process the tubes are annealed in a controlled atmosphere or under vacuum.
Normalized NBK The tubes are annealed above the upper transformation point in a controlled atmosphere or under vacuum.
