In order to ensure the performance of the cold drawn tube, it is generally tempered in the product processing engineering, and in order to meet the needs of different occasions, the performance of the cold drawn tube is put forward different requirements, so the selected tempering temperature is also difference. The following editors will introduce various tempering of cold drawn tubes.
If it is a cold drawn tube after low temperature tempering, its structure will become martensite, which means that this process not only ensures the advantages of the tube in terms of hardness and wear resistance, but also reduces the cold drawn tube Quenching internal stress and brittleness to avoid damage during use.
The tempering of the cold drawn pipe at medium temperature can make it get good yield strength, elastic limit and high toughness. Finally, high temperature tempering is left. The cold drawn tube after this process has improved the comprehensive performance of all aspects, including strength, hardness, plasticity, toughness, etc. This type of cold drawn tube can be important in some equipment. Be applied in the structure.
