You can do the removal of the material adhered to the stainless surface at the end of the soldering by rinsing the soldered product in water, or by sandblasting. When this temperature is reached, the solder is injected into the joint. When it melts, the rest of the metal heats up gradually to a bright red heat (850 degrees). Apply it to the bond in the form of a powder or paste. Remember to use copper solders, chromium-nickel, or silver-manganese ones during oven brazing in dry conditions.īorax is the most frequent flux, used for processing stainless steel. When you make products in corrosive conditions, solder them with silver tinol, containing a small percentage of nickel. Under the influence of hot solder (tinol), the work-hardened stainless material can crack, therefore soldering occurs after annealing, without heavy loads in the process of brazing.Ĭhoosing solder metal for stainless steel consider such characteristics: steel composition and soldering conditions. To minimize the formation of carbides, titanium is added or additional heat treatment is used upon completion of brazing.
The resulting carbides reduce the corrosion resistance of stainless steel significantly. Their release level depends on the soldering time, so the duration of the procedure must be reduced. Remember that some nickel-plated alloys can form carbides when heated to a temperature of 500-700 degrees. Understanding the process and preparation
