The carbon content of less than 0.25% carbon steel, because of its low intensity, low hardness and soft, it is also known as mild steel pipes. It includes the majority of ordinary carbon steel pipe and part of high-quality carbon structural steel, mostly used in engineering structures without heat treatment, and some by carburizing and other heat treatment is used for wear-resistant mechanical parts.
Low carbon steel large number of dislocations generated by deformation, the elastic interaction from the carbon and nitrogen atoms with dislocations in the ferrite, carbon, nitrogen atoms gather around the dislocations Line. This carbon, nitrogen atom and the dislocation line combination that old Coriolis air mass (Ke lop air mass). It will make the strength and hardness of the steel to improve the ductility and toughness decreased, a phenomenon known as the deformation aging.
