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) C in an amount ranging from 0.20 to 0.28
ii) Si in an amount ranging from 0.02 to 0.50
iii) Mn in an amount ranging from 0.1 to 0.8
iv) Cr in an amount ranging from 1.2 to 4.0
v) Mo in an amount ranging from of 1.8 to 3.0
vi) V in an amount ranging from 0.2 to 0.9
vii) Zr in an amount ranging from 0.001 to 0.015;
the balance being Fe.
The invention also relates to the use of a Fe-based powder for additive manufacturing and to a process for producing an object by additive manufacturing, comprising building an object by iteratively
i) melting particles comprised in a Fe-based powder as described herein
ii) solidifying the melt to form a built object
iii) tempering the built object.
