The present disclosure relates to a ferritic iron-chromium-aluminium (FeCrAl) powder which will provide seamless tubes of said powder and therefore will have a combination of good formability and form stability, good oxidation resistance and creep resistance. The present disclosure also relates to a seamless tube comprising a FeCrAl alloy. The FeCrAl powder comprises the following elements in weight %: Balance Fe and unavoidable impurities Al 4.0 to 6.0 0.01 to 0.10 Hf 0.05 to 0.25 O 0.01 to 0.04 Cr 19.0 to 23.0 Ta 0.01 to 0.40 Ti 0.01 to 0.15 C 0.01 to 0.05 N 0.01 to 0.10 Si Max 0.50 Mn Max 0.30 Zr 0.05 to 0.20 fulfilling the condition of: 2*[Y]−3*[O]<0, wherein the number of [Y] and [O] are in atom %.
