C35 vs C35E: 70% composition overlap. Some similarities but notable differences in alloying elements.
C35 vs C35E
Side-by-side chemical composition and mechanical property comparison.
Overview
C35
1.0501
Medium-carbon unalloyed steel with moderate strength. Good machinability and weldability. Used for lightly stressed components like levers, axles, bolts, and general machine parts.
C35E
1.1181
Mid-carbon unalloyed Q&T steel — 0.32-0.39% C. Good balance between strength and toughness/weldability. Modern designation for Ck35. Used for moderately loaded shafts, axles, bolts, connecting rods, and machine parts where C45 would be too hard and C22E too soft. Also suitable for surface hardening (flame/induction) to HRC 50-55.
