NICKEL-BASED HYDROCHLORIC ACID CORROSION RESISTANT ALLOY FOR SOLDERING

摘要

Provided is a nickel-based hydrochloric acid corrosion resistant alloy for soldering that is provided with corrosion resistance against hydrochloric acid, and when soldering various types of stainless steel, can be used for soldering at practical temperatures (1150°C or less), and has good bond strength and solderability to the substrate. This hydrochloric acid corrosion resistant alloy contains, in mass percent, 6.0-18.0% Mo, 10.0-25.0% Cr, 0.5-5.0% Si, and 4.5-8.0% P, with the remainder being 40.0-73.0% Ni and unavoidable impurities, and the total of Si and P being 6.5-10.5%. In this case, the alloy may contain 12.0% Cu or less, 20.0% Co or less, 15.0% Fe or less, 8.0% W or less, 5.0% Mn or less, and 0.5% or less of the total of C, B, Al, Ti, and Nb.
