Boiler HRC Hot Rolled Coil mild steel sS400 Q235 Q345 0.2mm - 4mm Thickness

The annealed structure of low carbon steel is ferrite and a little pearlite, with low strength and hardness, good plasticity and toughness. Therefore, its cold formability is good and can be used for cold forming methods such as crimping, bending and stamping. This kind of steel has good weldability. Low carbon steel with very low carbon content has very low hardness and poor machinability, and normalizing treatment can improve its machinability.

Low carbon steel has a great aging tendency, both quenching aging tendency and deformation aging tendency. When the steel is cooled from high temperature, the carbon and nitrogen in the ferrite are in a supersaturated state, and it can slowly form the carbon and nitrogen of iron at room temperature, so the strength and hardness of steel are improved, and the plasticity and toughness are reduced, this phenomenon is called quenching aging. Low carbon steel will produce aging even if it is not hardened and air cooled. The carbon and nitrogen atoms in ferrite interact elastically with the dislocation, and the carbon and nitrogen atoms gather around the dislocation line. This combination of carbon and nitrogen atoms and dislocation lines is called a Corleone air mass. It will increase the strength and hardness of steel and decrease the plasticity and toughness, this phenomenon is called deformation aging.
