Beschreibung
Zusammenfassung:	The invention relates to a plate heat exchanger and a method of manufacturing a plate heat exchanger. The plate heat exchanger includes a number of heat exchanger plates ( 1, 1', 1 '') which are provided beside each other and connected to each other by means of a braze connection. The heat exchanger plates are substantially manufactured in stainless steel containing chromium. The plate heat exchanger includes a number of port channels extending through at least some of the heat exchanger plates. Each port channel is surrounding by a connection surface ( 5 ) for connection of the port channel to a pipe member ( 6 ). The connection surface includes a material permitting brazing of the pipe member to the connection surface in a more easy manner than stainless steel.
