What metal was use in production of the luger p08

I want to make a CAD file for the p08 luger
I also plan to make the CAD file easily arrange by parts
So repair or part replacement can be done easier

but i need to know what it was made of
so any spec on the steel type and tempering would be appreciated

Hmm, No one knows? I'm a machinist myself, looked like a good question.

I have no idea, specifications show dimensions, but NOT type of metal.

Many things ae just not known. I doubt you could find this same information about the Ruger Security Six and it is onl 35 years old... ???

I am not aware of any technical information that specifies the steel type, but I think that some members may have part of the information from historical documents, but perhaps not the whole picture.

I would recommend the use of 4140 steel as that is the current type used by the industry for most firearms that end up getting blued, but as to hardness and temper of various parts? The only way to be certain would be to get a shooter Luger for testing and have the various parts hardness tested using Rockwell or Brinell tests... and then torture test those parts for durability.

If you don't own my Blueprint CD's... I suggest you order one (see the for sale forum sticky) and get your self a German - English technical dictionary. The blueprints are the largest source of technical information on the Luger.

It is a good question and we are getting closer to answering it. The main problem is the duration of the period the luger was made (some 50 years) during which the German standards developed into the DIN standards, which have now been surpassed by ISO standards.

Documentation dating from 1937 shows a number of DIN steel types and shapes (like round bar, squared bar, etc..) but it's a challenge to find the correct specifications and references.

I can give a couple of steel types:
Frame: DIN steel 50.11, forged.
Toggle and receiver parts, most stress parts: DIN steel C 25.61 and DIN steel C 60.61. Many of these in round bar or squared bar 'raw' shape.

I beleve Gerben found a good answer to the question, but if someone has the will and the equipment to do a test like John S. suggested, I can provide a broken frame and and probably some toggle parts. I have some chrap laying around perfect for this.. (both DWM and Mauser frames) just let me know:)
