摘要： The present invention relates to a Fe-based powder for additive manufacturing comprising the following elements in wt% based on the weight of all elements of the powder:
i) Ni in an amount ranging from 9.0 to 14.0
ii) Mo in an amount ranging from 7.0 to 9.0
iii) C in an amount ranging from 0.03 to 0.08
iv) Si in an amount up to 0.3
v) Mn in an amount up to 0.3
the balance being Fe and usual impurities. The invention also relates to the use of the Fe-based powder and a process of producing an object therefrom.
