Relationship between nitriding treatment time, treatment temperature, and hardness (nitrided steel)
Surface hardening treatment that hardens the surface of steel. Introduction of nitriding treatment time and the hardness transition curve of nitrided steel.
The Kyokuto Nitriding Research Institute Co., Ltd., which conducts gas nitriding treatment, annealing treatment, and more, will explain the relationship between nitriding treatment time, treatment temperature, and hardness (nitrided steel). A diagram shows the hardness distribution based on the nitriding treatment temperature. As the temperature increases, the surface hardness decreases. We have summarized the "nitriding treatment (SACM645) treatment time of 30 hours" in a table, and the "hardness transition curve of nitrided steel (SACM645)" is presented in a graph for explanation. *For more details, please download the PDF or feel free to contact us.
