Abstract
This experimental study investigates the nitriding effects on microstructure of wrought 17-4 PH stainless steel. Nitriding was carried out at 560 °C for 2 hours, resulting in significant improvements in hardness. Nitriding improves the hardness on the surface of the 17-4 PH steel and remains constant in the core. As a result of nitriding the harness increased 3.5 times the hardness of the wrought alloy. Microstructural analysis of both untreated and nitrided samples using a scanning electron microscope (SEM) equipped with energy-dispersive X-ray spectroscopy (EDS) revealed the formation of a nitride layer. The results show a relationship between nitriding temperature and nitride layer thickness, with higher temperatures leading to thicker layers.
