Behavior of Welded Joints From Some Stainless Austenite Steel Types During Nitriding Process

Abstract

Researches made on welded and nitrided samples from stainless austenite steel types show that nitriding thermo chemical treatment can be applied also for welded joints. As a result of the treatment, a diffusion layer with austenite dendritic layer was obtained, max hardness of 500 HV005- The layer's depth depends on the finishing degree of the structure. The finer the dendritic structure is the slower the diffusion process and smaller the layer depth.
