Cold deformation plasticity is high, generally for bending, calendering, bending and hammer arch processing, welding performance of arc welding and contact welding is good, gas welding thickness is small, the shape of strict requirements or complex shape of the workpiece is easy to crack. Cold extruded, carburized hardened steel. The steel belongs to low carbon carbon steel, the steel is low strength, toughness, plasticity and weldability are good. ≥245MPa, ≥402MPa, ≥28%. It is used to manufacture various mechanical parts which are not subjected to great stress but require high toughness. In the general machinery and automobile, agricultural machinery for the manufacture of high surface hardness requirements and heart requirements of carburizing and carburizing parts.

S45C steel is made of pure static steel by electric furnace, open furnace or pure oxygen converter process. The steel has uniform microstructure and no microstructure defects. The carbon content of the steel is more than 0.4%, excellent wear resistance, but the ductility is reduced, quenching is easy to deformation and cracking, so the heat treatment is very important, and must be quenched after tempering, to avoid the occurrence of tempering brittleness. The machinability of this kind of carbon steel can be improved by spheroidizing the steel. S45C is a high strength medium carbon quality steel. It is generally used under normal fire. When the mechanical properties of higher requirements, the use of tempering treatment. Cold deformation plasticity medium, annealing and normalizing workability is better than tempering. Used for manufacturing parts requiring higher strength, such as gear, shaft, piston pin, as well as mechanical workpiece, forging, stamping parts and bolts, nuts, pipe joints, etc. 45C is widely used in machinery manufacturing. This steel has good mechanical properties.
