Carbon steel flat washers, do you know the characteristics of carbon steel materials

Carbon steel flat washers are a common metal raw material in flat washers. Regarding the material properties of carbon steel, its strength and hardness are lower, and its plasticity and toughness are better. Xiaoshuo sorted it out, and let's understand with you: Carbon steel has a greater tendency to age, both quenching and deformation. When the steel is cooled quickly from a high temperature, the carbon and nitrogen in the ferrite are in a supersaturated state. It can also slowly form iron carbon and nitrogen at room temperature, so the strength and hardness of the steel increase, while the plasticity and toughness decrease. This phenomenon is called quenching aging. Low-carbon steel will produce aging even if it is not quenched but air-cooled. Low-carbon steel produces a large number of dislocations through deformation, and the carbon and nitrogen atoms in the ferrite interact elastically with the dislocations, and the carbon and nitrogen atoms gather around the dislocation line. This combination of carbon and nitrogen atoms and dislocation lines is called Korotkoff gas 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 plasticity and toughness of low carbon steel than quenching aging. There are two obvious upper and lower yield points on the tensile curve of low carbon steel. From the appearance of the upper yield point until the end of the yield extension, a surface wrinkle zone formed by uneven deformation appears on the surface of the specimen, which is called the Ludes zone. Many stamping parts are often scrapped because of this. There are two ways to prevent it. A high pre-deformation method, the pre-deformed steel will also produce Lüdes strips when stamping after being placed for a period of time, so the pre-deformed steel should not be placed too long before stamping. The other is to add aluminum or titanium to the steel to form a stable compound with nitrogen to prevent deformation and aging caused by the formation of Coriolis air mass.
