John S,
In the 1946 to 1977 era.
I seem to remember Working on many Stainless steel models that were silver soldered for research applications.
These models were typically of 18-8, 416, and 17-4 ph stainless steels.
Heat treatment was generally of no consideration as the use of these steels were chosen for corrosive resistance and other properties that were normal to non-heat treated applications.
Generally the flux was simply 20 mule team borax.
With the coming of the more advanced eutectic silver solder the demand for fluxes that were better applied to low temprature applications in the range of 350 to 1000 degrees developed.
I can see no reason why some of these low temp silver solders would not be applicable to the many grades of stainless steel, where there is consideration given to the precipitation hardening charactistics of these newer steels, and the application is kept within the realm of acceptablility.
