Stainless steel has a good corrosion resistance and a good high temperature mechanical properties. In this study, temperature dependence of elastic constants of thin cold rolled stainless steel has been measured by using the acoustic resonance method[1]. Identification of the vibration mode has been examined numerically and experimentally. The elastic constants at room temperature have been also measured by Pulse Echo method. In addition, the texture effect on the elastic constants has been analysed by assuming the specimen as orthorhombic structure.
