Spray forming is an advanced technology for the manufacture of homogeneous material from the melt. In this study, 20MnCr5 steel, a typical case hardening steel for gear and shaft production, has been spray formed and hot worked to semi‐finished bars. Shaft‐like specimens have been made from the spray‐formed material for distortion investigation. Material characteristics of the spray‐formed 20MnCr5 steel have been studied. In cooperation with other projects of the Collaborative Research Center SFB570 ‘’Distortion Engineering’’, evaluation of distortion behavior of the shaft specimens after machining and heat treatment has been made in comparison with continuous cast material. Spray‐formed 20MnCr5 steel shows lower distortion potential due to improved material homogeneity.
