The grain boundary character distributions, crystallographic textures of metastable austenitic stainless steel 301L during annealing were investigated by using electron back scatter diffraction (EBSD) technique. The effect of annealing temperature on the grain boundary character and texture was analyzed. The result shows that the texture of metastable austenitic stainless steel 301L is mainly composed of Copper {112}<111>, Brass {110}<112>, Goss {110}<001> and S {123}<634> after cold rolled annealing. With the increasing of annealing temperature, the texture intensity of 301L was gradually weakened and the density of Σ3 coincidence grain boundary increased but the density of other coincidence grain boundary had no significant change.
