What steel materials is used for chronograph hammers and other (none rotating) moving parts?

If there are missing parts of an older watch and it's not possible to find spare parts, what steel is recommended to start with?

Is there a description, video or  written guidelines to follow?

The picture is more of an illustrative picture than the real needed object.

There are several alloys used in industry but they aren't available in small quantities anywhere. But any good basic high carbon (hardenable) steel is OK, O-1 is a good one, and even more basic but  just as good would be 1095. Both of those are AISI (American) numbers, 1095 is designated as EN 1.1274 in Europe.

I found data  at one of the Swedish steel suppliers Sandvik

 https://www.materials.sandvik/en/materials-center/material-datasheets/strip-steel/20c/

and that the sizes of the material was acceptable to start with (see picture).

Thanks

Yes the 20C is an excelent spring steel from Sandvik. The problem is they dont sell it is small quantities.
As you live in Sweden there is a webshop to buy these material in small sheets.
We usually use these ones to measure gaps with but makes for example excelent reset hammers, just meassure what thikness the original hammer has and get out the jiggsaw,,,

Perfect with a "local shop", Thanks/tack!!

I think that this will take time, but missing hammer and wheel turner for the Audemars Freres repeater / chronograph , but i am not in a hurry with this one.
