Shenzhen Su's heat-treated stainless steel vacuum brazing
.&&&/&&#=> rCbR&& Another problem with stainless steel brazing is that the heating temperature has a serious impact on the structure of the base metal. The brazing heating temperature of austenitic stainless steel should not be higher than =>
℃, otherwise the grains will grow seriously. If the austenitic stainless steel does not contain stabilizing elements =>
or =>
Since the carbon content is high, brazing at the sensitization temperature (=>
~ =>
°C) should be avoided. To prevent the reduction of corrosion resistance due to the precipitation of chromium carbide. The requirements for selecting the brazing temperature of martensitic stainless steel are more stringent. One is to require the brazing temperature to match the quenching temperature to combine the brazing process with the heat treatment process. The other is to require the brazing temperature to be lower than the tempering temperature. To prevent the base metal from softening during the brazing process. The principle of brazing temperature selection for precipitation hardening stainless steel is the same as that of martensitic stainless steel, that is, the brazing temperature must match the heat treatment regime to obtain the best mechanical properties.
