More Information
Summary:The present invention relates to an Fe-Ni-based alloy which has a composition containing, in mass%, 0.005%-0.10% of C, 0.01%-0.10% of Si, 0.015% or less of P, 0.003% or less of S, 23.0%-27.0% of Ni, 12.0%-16.0% of Cr, 0.01% or less of Mo, 0.01% or less of Nb, 2.5%-6.0% of W, 1.5%-2.5% of Al and 1.5%-2.5% of Ti, with the balance made up of Fe and other unavoidable impurities, and which has excellent high-temperature characteristics and hydrogen embrittlement resistance characteristics.
