    In austenitic stainless steels, the Young's modulus ratio E100/Ehkl in single crystal is expressed as a function of the orientation parameter Γ: E100/Ehkl=1-2.027Γ. Under the presumption that this relationship stands up on commercial stainless steels with various chemical composition, the elastic stiffness cij was calculated as follows in connection with Young's modulus Ep of poly crystal austenitic stainless steels: C11=1.0311Ep, c12=0.6864Ep, c44=0.6246Ep. As a result, the elastic stiffness ratio c12/c44 and the anisotropy parameter Ai (=2c44/(c11-c12)), that are required in the dislocation analysis by modified Williamson-Hall method, are estimated constant at c12/c44=1.099 and Ai=3.624.
