Abstract
An electroless nickel plating film layer is formed over a surface of a base material of a forceps piece made of austenitic stainless steel. The forceps are chemical resistant. The electroless nickel plating film layer displays a hardness suitable for the forceps and superior toughness, and allows an edge to be put on the electroless nickel plating film layer more easily than a hardened steel that has the same hardness.
