Testing and prediction of mechanical properties for AISI 300 series steels

This paper presents a comparison of five AISI 300 series stainless steels (304, 314, 316L, 316Ti, 321), commonly used in marine industry. Steels are compared based on experimentally determined and numerically predicted mechanical properties. Afterwards, change of some of the properties is predicted using regression analysis. Experimentally, stress-strain curves are determined at several temperatures and from them ultimate tensile (UTS) and yield (YS) strengths extracted. Charpy test is performed to determine materials’ impact resistance. Numerically, single specimen test method is simulated and FE stress analysis results are used to calculate J-integral to quantify crack driving force.
