  • Steel Material for Forming Components Using Additive Manufacturing and Use of a Steel Material of This Type
    Publication number: 20230220526
    Abstract: The invention relates to a steel material which allows for components to be formed with low residual stress via additive manufacturing without pre- or post-heating. The steel material consists of a steel with the following composition, in wt. %: C: 0.28-0.65%, Co: <10.0, Cr: 3.5-12.5%, optionally Mo: 0.5-12.5%, wherein the sum of the content of Cr and Mo is 4-16%, the Ni equivalent Ni_eq calculated according to the formula Ni_eq [%]=30% C+% Ni+0.5% Mn from the C-content % C, the Ni-content % Ni, the Mn-content % Mn fulfills the condition (1) 10%?Ni eq?20%, and alongside C, optionally respectively up to 9% Mn and up to 4.5% Ni are provided to fulfill condition (1), wherein the Cr equivalent Cr_eq calculated according to the formula Cr_eq [mass]=% Cr+% Mo+1.5% S+0.
