Filter Housings, which weighs 2.2kg, chooses 20# material, 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. Deformation aging is more harmful to the ductility and toughness of low carbon steel than quenching aging, and there are obvious upper and lower yield points on the tensile curve of low carbon steel.

From the appearance of the upper yield point to the end of yield extension, a surface corrugation band, called Luders zone, is formed on the surface of the sample due to uneven deformation.
