Equivalent Material - French to American 2

[JOHNMORRIS]

I have a fastener of French material designation. The material information from the specification reads: Materiau indique dans la norme NF L 22-031-. Code suivant norme NF L 09-752.

Additionally, there is a surface treatment of: Code suivant norme NF L 09-753.

Any help identifying this material would be greatly appreciated.

Regards,
John Morris

You might want to try stahlschlussel, "key to steel".

hope this helps. It has references to most foreign grades of steel.

The three items that you have identified are French aerospace standards. None of them refer to one specific grade or treatment. You can obtain these standards by visiting the website for the French standardization organization AFNOR:

The standards you refer to are no use in finding out the material of your fastener. one of the two specifications are documents which help you to choose materials for a particular part, and the other defines the material once you know the two-letter material code which forms part of the fastener reference. If the fastener is a bolt, the head should be marked with this two-letter material code. Tell me what the code is and I will let you know the material.
