Abstract
An iron based brazing material for joining of objects by brazing represents an alloy, which apart from iron contains maximum 40% Cr, maximum 16% Mn, maximum 40% Ni and maximum 7% Mo, all stated in weight percent and 6-40% Si, which Si-addition lowers the liquidus temperature, that is the temperature at which the brazing material is completely melted. A brazed product is manufactured by brazing of iron based objects with an iron based brazing material which is alloyed with a liquidus lowering element as Si, possibly also with B or P.
Claims8
Iron based brazing material for joining objects by brazing characterized in that the brazing material consists of an alloy which contains at least 50% Fe and includes 0-30% Cr, preferably 9-30% Cr, maximum 5% Mn, 0-25% Ni and maximum 7% Mo, 0-1% N and 6-20% Si, all stated in weight percent, which Si-addition lowers the liquidus temperature, that is the temperature when the brazing material is completely melted.
Iron based brazing material according to any of the preceding claims, characterized in that the brazing material is produced by gas- or water atomising or melt-spinning.
