Method for determining the organizational changes in steel due to re-annealing and the depth of quenching.
[Reproduction of Private Spring Preparatory School Lecture 59] Explanation of reversion! Also explaining martensite structure and changes in structure.
Today, let's study tempering. Steel that has been fully hardened becomes martensitic, but this is extremely hard, so it must be softened to an appropriate hardness, up to the spring hardness, through tempering. The range of tempering temperatures that can achieve spring hardness is 450 to 540 degrees, and the structure will be in a tempered troostite state. Let’s explain the changes in structure due to tempering in a bit more detail. *The detailed content of the article can be viewed in the PDF. For more information, please feel free to contact us.*
