Abstract (en)
[origin: WO0121848A1] The invention relates to creep-resistant iron-nickel alloys with a low expansion coefficient that contain (in weight %), in addition to 0.02 to 0.3 % C, a maximum of 1 % Mn, and a maximum of 1 % Si, an Mo content of 0.1 to 2.5 % and/or a Cr content of 0.1 to 2.5 % </=1.0 % Nb, as well as an Ni content of 31.0 to 45.0 %, remainder iron and production-related impurities. The inventive alloy has a thermal expansion coefficient of <6.0 x 10<-6>/K in the temperature range of 20 to 100 DEG C.
