60mn is a high-quality carbon structural steel with slightly higher hardness, elasticity, and hardenability, and good machinability in the annealed state. Material name: 60Mn Material type: high-quality carbon structural steel Characteristics and application examples: Strength, hardness, elasticity, and hardenability are slightly higher, with good machinability in the annealed state, but poor cold deformation plasticity and weldability. It has overheating sensitivity and temper brittleness tendency. Suitable for large-sized coil springs, leaf springs, various round flat springs, spring rings, cold drawn steel wires and springs.
