摘要： The invention relates to an iron based material for coating of surfaces which comprises a binding phase in the form of a corrosion dense alloy which contains at least 50% Fe, 12-30% Cr, maximally 5% Mn, 0-40% Ni, preferably 6-20% Ni and 0-7% Mo and 0-1% N and 6-20% Si, all stated as weight percent, which addition of Si lowers the liquidus temperature, that is the temperature at which the binding phase is completely melted. The invention also aims at products of metal coated with the iron based material mentioned above.

摘要： 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.
