The higher the silver content, the stronger the bond but the hotter the temperature needed to melt the filler metal. Technically, you can either braze or solder, though you cannot braze with solder or solder with brazing rods. But you can attach copper to steel with silver solder using a propane torch, and call it whatever you like.
Like Type 302, Types 304 and 304L stainless steel have excellent resistance to a wide range of corrosive media and to atmospheric exposures. The low carbon content of Type 304 and especially 304L, by reducing or eliminating carbide precipitation due to welding, makes these types of stainless suitable for a much wider range of corrosive service

It can readily join stainless steel to itself, and is an alternative to welding. The recommended filler rod for brewing service is AWS type BAg-5, and its temperature range 1370-1550°F (743-843°C). While brazing can provide a stronger joint, the high brazing temperatures can be bad for stainless steel.

Is there a trick to Brazing Copper to Steel or Stainless Steel? My Machinist buddy needed me to silver braze some copper washers to stainless steel bolts and also a copper block to a swivel foot. So here is the video with a few tips on silver brazing copper to steel and brazing stainless steel bolts to some copper washers.
Type 304. Type 304 stainless steel is basically the same as Type 302 except for a higher chromium and lower carbon content. Its lower carbon minimizes chromium carbide precipitation due to welding and its susceptibility to intergranular corrosion.
Shiri et al.  performed gas tungsten arc welding of CP-copper to 304 stainless steel using Ni-Cu-Fe, 304 stainless steel and Cu filler materials and concluded that copper is the best filler
