Trying to match DIN WK numbers to source standard
Trying to match DIN WK numbers to source standard
(OP)
Hi
I have two DIN specifications with matching Wk numbers, and I am trying to find the source DIN/ISO standard. An extensive search by two of us has so far not found anything. They are
11 NiMoV 5 3, Wk 1.6341
GS14NiCrMo 106, Wk 1.6779
Thanks

RE: Trying to match DIN WK numbers to source standard
Perhaps what confuses you is that Werkstoffnummern are not used exclusively by DIN standards.
Indeed, there are at least two additional German institutions that employ the same designation, i.e. VDEh (Verein Deutscher Eisenhuettenleute, German for "Iron and Steel Institute") and VdTÜV (Verband der Technischen Überwachungs-Vereine, German for "Association of Technical Monitoring Clubs"). Both have their own material specifications, named respectively SEW (Stahl Eisen Werkstoffblatt) and WB (Werkstoffblatt); and in this case, they both cover the materials you are looking for:
1.6341
1.6779
Actually there is also a third one, the BWB (Bundesamt für Wehrtechnik und Beschaffung, German for Federal Office of Defense Technology and Procurement). In this case, the specifications are WL (Werkstoffleistungsblätter) and to my knowledge they cover aerospace material grades.

1.6341 11NiMoV5-3 DIN SEW 028 (05/1993)
1.6779 G14NiCrMo10-6; GS-14 NiCrMo 10 6 † DIN SEW 520 (09/1996), DIN SEW 685 (03/2000)
I cannot tell for 1.6341, but 1.6779 is in both mentioned standards.
