Zusammenfassung:	Iron-chromium based brazing filler metal This invention relates to a brazing filler metal with excellent wetting behaviour on stainless steel base material. The brazing filler metal produces a brazed joint with high strength and good corrosion resistance. The brazing filler metal is suitable for brazing stainless steel and other materials where corrosion resistance and high strength is required. Typical examples of applications are heat exchangers and catalytic converters. The iron-chromium based brazing filler metal powder according to the invention comprises: between 11 and 35wt% Chromium, between 0 and 30wt% Nickel, between 2 and 20wt% Copper, between 2 and 6wt% Silicon,15 between 4 and 8wt% Phosphorous, between 0-10wt% Manganese, and at least 20 wt% iron.
