Influence of grain size in mechanical properties of austenitic stainless steels
Keywords:Grain size, Metastable steels, Stable steels, Elastic limit, Tensile strength
The goal of this work is to study the influence of the grain size on mechanical properties of austenitic stainless steels. The study covers both, stable stainless steels and metastable steels. A relevant topic is to identify the differences in the behaviour of both types of steels. First of all, several steel taps are taken into account and by this way the average of results are derived. A sorted collection of them show its behaviour. Several rules are identified, like straight relationship between the number of grain size (ASTM) and the 0.2 % proof stress and the tensile strength and inverse relationship with the elongation. Specific studies analyzing the relevance of nickel are performed. Finally main conclusions and valuations are presented and some statistic results of mechanics properties and steel taps are performed in order to get better prediction of their behaviour.
