Medium Carbon Steel
Medium carbon steel is a carbon steel with a carbon content of 0.25% to 0.60%.
Medium carbon steel offers balanced plasticity, toughness, strength, and good machinability after quenching and tempering, though its weldability is relatively low. Medium carbon steel has higher strength and hardness than low carbon steel, with slightly lower plasticity and toughness. Hot-rolled and cold-drawn medium carbon steel bars can be used directly without heat treatment or after quenching and tempering.
After quenching and tempering, medium carbon steel provides comprehensive mechanical properties and is widely used across medium-strength applications. In addition to construction materials, medium carbon steel is extensively used to manufacture mechanical components such as air compressors, pump pistons, steam turbine impellers, heavy machinery shafts, worm gears, gears, and wear-resistant parts including crankshafts, machine tool spindles, rollers, and hand tools.
