Free-cutting variant of 50CrMo4 — S 0.020-0.040% for machinability. Higher C (0.46-0.54%) than 42CrMoS4 = higher hardness after Q&T (UTS 1100-1300 MPa). Used for high-strength shafts, torsion bars, and heavy-duty bolts produced on CNC automatics where maximum CrMo strength with machinability is needed.
