Nickel-chromium alloy.

摘要

The present invention provides a nickel-chromium alloy in which it has an excellent mechanical character and improves a pitting corrosion resistance, a stress corrosion cracking resistance and a crystal boundary etching resistance, and the Ni-Cr alloy is obtained by carrying out an annealing treatment under required conditions, said alloy having the following composition: in therms of by weight, 40 - 70% of Ni; 0.015% or less of C; 1.0% or less of Si; 25 - 35% of Cr; 1.0% or less of Mn; 0.030% or less of P; 0.020% or less of S and the residue comprising Fe and impurities. i
