High Cr-containing Ni-based alloy with excellent high temperature phase stability

摘要

PROBLEM TO BE SOLVED: To provide a high Cr-containing Ni-based alloy excellent both in corrosion resistance and high-temperature phase stability with improved embrittlement behavior.;SOLUTION: The high Cr-containing Ni-based alloy has a composition containing ≥43-47% Cr, 0.3-1.5% in total of one or two elements selected from Ta and Nb, 0.001-0.05% Mg, 0.001-0.04% N, 0.05-0.5% Mn, and 0.001-0.05% V and, if required, one or two elements selected from 0.05-1.0% Fe and 0.01-0.1% Si, and the balance being Ni and inevitable impurities, in which the amount of C included as the inevitable impurities is controlled to less than 0.05%.;COPYRIGHT: (C)2008,JPO&INPIT
