Abstract
An austenitic stainless steel screw having excellent non corroding properties and a high level of hardness is disclosed, together with a method for manufacture of such screws. A hard nitrided layer is formed on the surface of the austenitic stainless steel screw, and the nitrided layer is removed over predetermined parts such as the head and part of the shank of the screw.
