摘要：The present invention provides a martensitic stainless steel strip for razor blades in annealed state comprising a continuous processed groove being formed with thermal energy in a longitudinal direction on one side of the strip at a position with a predetermined distance from one edge; and a continuous changed structure area being formed with thermal energy in a longitudinal direction on opposite side of the strip at a position having a predetermined distance from the edge, wherein the processed groove functions as a splitting portion of the strip. In addition, the present invention provides a method for manufacturing the steel strip for razor blades.
