Nickel-based alloy

Abstract

Nickel-based alloy having the following composition, in percent by weight (wt.-%): C equal to or less than 0.05, Si equal to or less than 1.0, Mn 0.5-1.5, P equal to or less than 0.03, S equal to or less than 0.03, Cr 31.5-36.0, Mo 7.0-10.0, N 0.08-0.18, Cu equal to or less than 0.4, Fe 2.0-6.5, optionally Al up to 0.30, optionally one of Ca or Mg each up to 0.05 or REM up to 0.5, optionally up to 0.0050 of B, balance Ni and normally occurring impurities up to at most 1.5 wt.-% in total; wherein the composition fulfils the requirement of Equation 1: ENi≥1.864*Ecr−24.0 (Equation 1) wherein ECr=[wt.-% Cr]+[wt.-% Mo]+1.5*[wt.-% Si], and ENi=[wt.-% Ni]+30*[wt.-% C]+30*[wt.-% N]+0.5*[wt.-% Mn]+0.5*[wt.-% Cu],
