What are the choices of tempering technologies for high-precision cold-drawn tubes: In order to ensure the performance of cold-drawn tubes, they are usually subjected to tempering treatment during the product processing. Moreover, to meet the needs of different applications, different requirements are put forward for the performance of cold-drawn tubes, so the tempering temperatures used are also different. The following is a comprehensive introduction to various tempering methods for cold-drawn tubes. If the cold-drawn tube is treated by low-temperature tempering, its structure will become martensite. That is to say, this technology not only ensures the advantages of the tube in terms of hardness and wear resistance, but also can reduce the quenching internal stress and brittleness of the cold-drawn tube to avoid damage during use. The medium-temperature tempering of cold-drawn tubes can make them obtain good yield strength, elastic limit and high toughness. High-temperature tempering: After this technical treatment, the comprehensive performance of the cold-drawn tube is improved in various aspects, including strength, hardness, plasticity, toughness, etc. Such cold-drawn tubes can be used in the main structures of some equipment.
