Abstract Oxidation characteristics of Type 304 stainless steel in CO2 were observed over the temperature range 1100–1800 F (593–982 C). Although in general oxidation rate curves were parabolic, several periods were observed in which they were approximately linear. These breaks were reproducible and thought to be associated with changes in rate-controlling step of the oxidation process. Carburization of Type 304 stainless steel during exposure to CO2 was observed. Several other alloys were studied, to determine earbiorization mechanism. These included Type 406 stainless steel, a British 20 Cr– 25 Ni, niobium-stabilized steel, Inconel, iron, Fe–1 Cr, Fe–3 Cr, and Fe–10 Cr. Correlation was found between carburization and chromium content, with low chromium favoring and higher chromium inhibiting this reaction. Mechanism was proposed based upon influence of chromium on type of surface oxide formed.

Type 304 Stainless Steel

Application of microforming in various research areas has received much attention due to the increased demand for miniature metallic parts that require mass production. For the accurate analysis and design of microforming process, proper modeling of material behavior at the micro/meso-scale is necessary by considering the size effects. Two size effects are known to exist in metallic materials. One is the “grain size” effect, and the other is the “feature/specimen size” effect. This study investigated the “feature/specimen size” effect and introduced a scaling model which combined both feature/specimen and grain size effects. Predicted size effects were compared with experiments obtained from previous research and showed a very good agreement. The model was also applied to forming of micro-features by coining. A flow stress model for Type 304 stainless steel taking into consideration the effect of the grain and feature size was developed and implemented into a finite element simulation tool for an accurate numerical analysis. The scaling model offered a simple way to model the size effect down to length scales of a couple of grains and extended the use of continuum plasticity theories to micro/meso-length scales.
