摘要:
A brazing method for brazing article of stainless steel comprises the steps of: Providing a brazing paste comprising a metal powder comprising: Trace amounts of C and S; 2-2,5% Mo; 12-13% Ni; 17,5-18,5% Cr; 6-8.3% Si; 4.5-5.5% Mn; all percentages being given by weight, balance being iron (Fe). The metal powder has a particle size less than 106 μm, wherein the metal powder is made into a paste by addition of binder and solvents. The paste is applied on or close to contact points between the stainless steel articles to be brazed, whereafter the articles are placed in a furnace. The furnace is heated to a temperature lower than the temperature at which the metal powder of the brazing paste is completely melted, whereafter the stainless steel articles are allowed to set by lowering the temperature.
