Abstract

PURPOSE: To obtain exterior decoration parts made of alloy with high corrosion resistance in place of austenitic stainless steel by adding Cr, Mo and W to Ni base in a well-balanced state and further adding a specified amount of Fe.
CONSTITUTION: Exterior decoration parts for a pocket watch are made of alloy consisting of, by wt., 16W25% Cr, 5W30% Mo, 1W5% W, 5W25% Fe, ≤0.03% C, ≤2% Zr, Ta, V, Nb or Ta or ≤5% two or more among them and the balance Ni. By this alloy composition the corrosion resistance of complicated parts such as a watch mesh band apt to undergo crevice corrosion is maintained. This alloy has superior mechanical properties as well as corrosion resistance.
