Medium Carbon Steel
Medium carbon steel is a kind of carbon steel which has 0.25%~0.6% of carbon content.
Medium carbon steel has a certain degree of plasticity, toughness, strength, and good machinability after quenching as well as cutting performance but has poor welding performance. Strength and hardness higher than low carbon steel, plasticity and toughness lower than low carbon steel. Hot-rolled and cold-drawn materials can be used without heat treatment, and they can also be used after heat treatment.
The medium carbon steel has good comprehensive mechanical properties after quenched and tempered, so medium carbon steel is most widely used in various uses of medium strength level, in addition to being used as a building material, it is also widely used for manufacturing various mechanical parts. Such as air compressors, pistons of pumps, impellers of steam turbines, shafts of heavy machinery, worm gears, gears and parts with wear-resistant surfaces, such as: crankshafts, machine tool spindles, rollers, fitter tools, etc.
