If you really have a sufficient understanding of pipeline pipes, you can better understand that when using this type of pipeline, there are actually some specific types of tempering. If you have a better understanding of this knowledge, the following will explain the specific classification of tempering in pipeline pipes:
1. Low temperature tempering
The temperature ranges from 150 ° to 250 °, with the aim of maintaining the high hardness and wear resistance of quenched steel, in order to reduce the internal stress and brittleness of quenching, and avoid cracking or premature damage during use. It is mainly used for various high carbon cutting tools and measuring tools. After tempering, the hardness is very good.
2. Medium temperature tempering
250 °~500 °, this is the tempered bending body, which aims to obtain high yield strength, Elastic Limit and high toughness. So it is generally applied to the treatment of some hot working molds, in order to achieve the corresponding hardness requirements.
3. High temperature tempering
From 500 ° to 650 °, the obtained microstructure is tempered sorbite. Traditionally, a combination of quenching and high-temperature tempering is used for heat treatment, which is called quenching and tempering treatment. The purpose is to obtain comprehensive mechanical properties with excellent strength, hardness, plasticity, and toughness. In this aspect, it is widely used in automobiles, as well as important structural components such as machine tools, such as bolts, gears, shafts, etc. Its tempering hardness also needs to meet corresponding requirements.
These are the three classifications of pipeline pipes. In fact, the content discussed by Tianjin Yuantai Derun Steel Pipe Group will become more detailed and require detailed understanding. This way, pipeline pipes can be used effectively, allowing enterprises to solve some problems and truly play their role.
