Three Characteristics of High-Strength Alloy Steel Pipe Strengthening
Under normal circumstances, the microstructure of the alloy steel pipe determines the structural properties of the steel pipe. However, the microstructure strengthening determines the microstructure. After the rolling of the cold-rolled alloy steel pipe is completed, as the cooling environment changes, various bainite, martensite, and other structural organizations in the structure also change, which also leads to a great change in the structural properties of the steel pipe. In this way, more incompetent steel pipes can be obtained to meet different performance requirements.
1. The mother phase is required for the reinforcement of the tissue, ie the mother phase of the steel reinforcement must be contained in the elements of the steel tube.
2, organizational strengthening is a process, including organizational deformation and organizational proliferation, with the cooling environment changes, there may be two changes in the structure of alloy steel pipe, that is, proliferation and non-proliferation, in the low-temperature environment, no proliferation determines the organization Deformation process; In high-temperature environments, diffusion determines the change in organizational structure.
3. There are two important factors for organizational strengthening: organizational strain and environmental cooling. For example, in a heating environment or a cooling environment, the microstructure of an alloy steel pipe gradually changes as the temperature changes, and the energy state changes from low to high. In addition, looking at the spot of the steel pipe can know that in the alloy steel pipe, a small amount of medium contains an extremely fine density. Therefore, when adjusting the structural performance of the steel pipe, attention must always be paid to the organizational performance of the alloy steel pipe.
