摘要: The invention is a nitriding treatment method for a steel component including at least two nitriding treatment steps, i.e., a first nitriding treatment step in which a nitriding treatment is performed to a steel component under a nitriding gas atmosphere of a first nitriding potential, and a second nitriding treatment step in which another nitriding treatment is performed to the steel component under another nitriding gas atmosphere of a second nitriding potential lower than the first nitriding potential, after the first nitriding treatment step. The first nitriding treatment step and the second nitriding treatment step is performed at a temperature within a range of 500 °C to 590 °C. The first nitriding potential is a value within a range of 0.300 to 10.000. The second nitriding potential is a value within a range of 0.253 to 0.600.
