Abstract (en)
[origin: WO2019224287A1] The invention relates to an austenitic alloy comprising the following elements in weight%: C ≤ 0.03; Si ≤ 1.0; 5 Mn ≤ 1.5; S ≤ 0.03; P ≤ 0.03; Cr 25.0 to 33.0; Ni 42.0 to 52.0; 10 Mo 6.0 to 9.0; N 0.07 – 0.11; Cu ≤ 0.4; Balance Fe and unavoidable impurities; and characterized in that the austenitic alloy fulfills the following condition: ENi>1.864*ECr-19.92 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]. The invention also relates to a manufacturing method and an object comprising said alloy. The alloy and objects made thereof have less than 0.3 % intermetallic phases after solidification.
