Uniform, compact and precipitate free hybrid solution layer (nitrogen and carbon rich) was succesfully formed on the surface of a 316Ti austenitic stainless steel by low temperature nitriding process (below 450 degrees C) in a fluidized bed furnace. After the nitriding, 316 Ti austenitic steel exhibited extremely high surface hardness (1690 HV0.05) when compared to the hardness of as-received state (295 HV0.05). Formation of solid solution layer, which did not lead any embrittlement effect during tensile and bending tests, enhanced the pitting corrosion resistance, remarkably.
