Ni-Cr Based Alloy Brazing Material Containing Trace Amount of V

摘要

Disclosed is a Ni—Cr-based brazing alloy including, on the basis of mass %: 15%Cr30%; 3%P12%; 0%Si8%; 0.01%C0.06%; 0%≤Ti+Zr0.1%; 0.01%V0.1%; 0%≤Al0.01%; 0.005%O0.025%; 0.001%N0.050%; 0%≤Nb0.1%; and the balance being Ni and incidental impurities. Inequality (1): 0.2≤0.24V %/C %≤1.0 is satisfied if the alloy contains no Nb, and Inequality (2): 0.2≤(0.24V %+0.13Nb %)/C %≤1.0 is satisfied if the alloy contains Nb. Also disclosed is an inexpensive Ni—Cr-based brazing alloy containing a trace amount of V for use in the production of stainless steel heat exchangers and other steel articles. The alloy has a low liquidus temperature and high corrosion resistance, and achieves high brazing strength.
