DIN (German industrial standard) Metal Yield Strengths

[Jac1542]

Im compiling a program that calculates required torque for bolts. I can't seem to find any specs pertaining to the yield strength of DIN metals. If anyone knows where these could be found, online or ordered I would greatly appreciate the help.

The web site for the German DIN organization is:

http://www.din.de

The default is of course German, but in the upper right corner is a button for "English Version", click that and you have the site in English. That should give you a start to search for the specs you are looking for.
If I remember right, DIN 2230 is one for bolts, just fyi.
