Rolling Direction Effects on Tensile Results for 304 Stainless Steel
Faculty Sponsor
Patrick Ferro, Gonzaga University
Research Project Abstract
Dogbone specimens of two different geometries were plasma cut from sheets of 304 stainless steel. The specimens (for each of the two different geometries) were plasma cut from parallel to and perpendicular to the sheet rolling direction. The work seeks to identify the effect of rolling direction on mechanical properties of 304 stainless as part of a larger effort to study the effect of gaseous hydrogen exposure on mechanical properties of materials that are suggested for future hydrogen designs. The specimens were exposed to one atmosphere hydrogen for one week, or were unexposed, prior to tensile testing. The specimens were pulled to failure at different strain rates ranging between 0.016 in/min and 0.15 in/min. Continued experimentation will correlate the tensile results with bending fatigue data for specimens that are plasma cut from each of the different orthogonalities.
