ABSTRACT:
An iron-based brazing alloy suitable for brazing iron-based alloys subject to high temperature environments. The resulting brazement contains little or no undesirable chromium boride (CrB) phase. Manganese, substituted for boron, depresses the melting point of the brazing alloy and vaporizes during the brazing cycle. This vaporization, by adjusting the relative proportions of the remaining elements, raises the remelt temperature of the brazement.
