Title (EN) SOLDER MATERIAL FOR STAINLESS STEEL COMPONENTS, PARTICULARLY FOR THE FURNACE SOLDERING OF HEAT EXCHANGERS FOR GASES
(FR) MATERIAU DE SOUDURE POUR COMPOSANTS EN ACIER INOXYDABLE, EN PARTICULIER POUR LE SOUDAGE AU FOUR D'ECHANGEURS DE CHALEUR POUR GAZ
Abstract: front page image
(EN)Solder material (8) for stainless steel components, particularly for the furnace soldering of heat exchangers (1) for gases, said solder material (8) being made of an alloy containing boron, and is characterized in that it comprises a percentage of niobium capable of reacting with the nitrogen contained in the stainless steel itself of the components that are to be soldered, being liable to form nitrides of niobium and thus preventing the nitrogen from reacting with the boron of the solder material (8).
(FR)Matériau de soudure (8) pour composants en acier inoxydable, en particulier pour le soudage au four d'échangeurs de chaleur (1) pour gaz, ledit matériau de soudure (8) étant fabriqué dans un alliage qui comprend du bore, et qui se caractérise en ce qu'il comprend un pourcentage de niobium capable de réagir avec l'azote contenu dans le propre acier inoxydable des composants à souder, étant susceptible de former des nitrures de niobium et évitant ainsi que l'azote ne réagisse avec le bore du matériau de soudure (8).
