A chain for a work implement has lateral connecting members connected to central driving members via studs. The stud has two lateral portions spaced apart from one another by a collar. A driving member is mounted pivotably on the collar. At the collar the stud has a surface layer harder than the base material. For a high chain service life, the stud has a diffusion layer above a surface layer above the base material. To produce the stud, the stud is provided with a diffusion layer at least at the collar, and a surface region of the collar is hardened, such that a surface layer is formed between the diffusion layer and the base material of the stud. For a method for producing a driving member, the driving member is provided with a diffusion layer at least at a circumferential surface of a hole and the driving member is hardened.
