Selection of tempering process for precision cold drawn tubes
If it is a cold-drawn pipe after low-temperature tempering treatment, its structure will become martensite, which means that this process not only ensures the advantages of the pipe in terms of hardness and wear resistance, but also reduces the quenching internal stress and brittleness of the cold-drawn pipe to avoid damage during use.
The medium-temperature tempering of cold drawn tubes can obtain good yield strength, elastic limit and high toughness. Finally, high-temperature tempering is left. The cold-drawn tube processed by this process can improve its comprehensive performance in all aspects, including strength, hardness, plasticity, toughness, etc. Such cold-drawn tubes can be used in important structures of some equipment.
