What Steel?

[LiamPSD]

HI there, I have an old production drawing and on it the material specifcation calls for TL-4223. This is a German drawing from 1987. does anybody have any idea as to what grade steel this would be today?
many thanks,
Liam

I think this may be a proprietary specification from Volkswagen. I don't know about this one in particular, but they do use TL ### designations.

Cory

Just wanted to confirm Cory's information that this is likely a VW specification. Sorry I can't provide any details on composition, etc. Depending on the type of component, I would recommend contacting German steel companies to see if they can offer some assistance. Eng-tips member richardbuss may be the best person on this forum to help...
