Abstract
The invention relates to an iron-nickel-chromium-silicon alloy comprising (in wt.-%) 19 to 34% or 42 to 87% nickel, 12 to 26% chromium, 0.75 to 2.5% silicon, and additives of 0.05% to 1% Al, 0.01 to 1% Mn, 0.01 to 0.26% lanthanum, 0.0005 to 0.05% magnesium, 0.04 to 0.14% carbon, 0.02 to 0.14% nitrogen, and further comprising 0.0005 to 0.07% Ca, 0.002 to 0.020% P, a maximum of 0.01% sulfur, a maximum of 0.005% B, the remainder comprising iron and the usual process-related impurities
