An iron-based brazing material for joining of objects by brazing represents an alloy, which apart from iron contains 9 to 30 wt% Cr, 0 to 5 wt% Mn, 0 to 25 wt% Ni, 0 to 7 wt% Mo, 0 to 1 wt% N, and 6 to 20 wt% 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.
L'invention porte sur un matériau de brasage à base de fer permettant d'assembler des objets par brasage. Ledit matériau est composé d'un alliage qui contient au moins 50 % de fer et 0 à 30 % de chrome, de préférence 9 à 30 % de chrome, un maximum de 5 % de manganèse, 0 à 25 % de nickel, un maximum de 7 % de molybdène, 0 à 1 % d'azote et 6 à 20 % de silicium, chacun des éléments étant exprimé en pourcentage pondéral. L'addition de silicium abaisse la température de Liquidus, température à laquelle le matériau de brasage est entièrement fondu. Un produit brasé est fabriqué par le brasage d'objets à base de fer avec un matériau de brasage à base de fer, lequel est allié avec un élément abaissant la température Liquidus, tel que le silicium, ou encore, si possible, le bore ou le phosphore.
