Abstract

PURPOSE: To improve corrosion resistance by suppressing the polarization activity of stainless steel by manufacturing a timepiece band and case using stainless steel containing less than 1.0 % Ni.
CONSTITUTION: The timepiece band and case are manufactured by using a stainless steel containing 20 to 40 % Cr, less than 1 % Ni, and 0.2 to 5 % Mo. The inclusion of Cr and Mo increases corrosion resistance and also the inclusion of less than 1.0 % Ni assists in suppressing polarization action of steel. In this case, the C(carbon) content is reduced as much as possible to suppress the formation of the carbide of Cr, thus improving the anticorrosive effect to a great extent.
