Belongs to the carbon structure steel medium carbon high strength carbon structure steel, after quenching has high strength and hardness, this kind of steel is of medium machinability, but hardenability is low, the critical diameter of water is 13*30mm, and water quenching from cracking tendency. The steel is usually used after heat treatment such as normalizing or quenching and tempering, or high-frequency surface quenching, and can be used for forging.
C50(1.5040） is high strength medium carbon steel, generally used in normalizing or quenching and tempering, used for manufacturing mechanical workpieces and spring parts with high wear resistance requirements and little dynamic load and impact effect, such as forged gear, pull rod, roller, shaft, friction disc, agricultural ploughshare, heavy load mandrel, etc.
