Abstract

The paper presents the results of investigation into corrosion resistance behaviour of gas nitrided 316L austenitic stainless steel and 9.3%Cr ferritic steel. Gas nitriding is a heat treatment technique that improved fatigue life, strength and wears and localized corrosion resistance. However, at certain temperature the steel becomes sensitized to possible intergranular corrosion. The heat treatment permits the formation to small precipitate particles of chromium carbide, Cr23C6 by reaction between the chromium and carbon in the material. During the heat treatment process, the samples are heated at two different temperatures for two samples which are at 600°C and 900°C in a tube furnace through which nitrogen gas is allowed to pass. The nitrogen reacts with the steel penetrating the surface to form nitrides. In order to investigate the presence of chromium carbine in grain boundary, further studies were conducted to analyse the microstructure, physical and mechanical properties by comparing the specimens before and after the nitriding process.
