Abstract
PURPOSE: To simply and cheaply manufacture the above mentioned steel sheet improved the strength for the pattern galling by carrying out zinc electroplating of the steel sheet in plating bath added SrCO3 having a specific concentration.
CONSTITUTION: SrCO3 is added in plating bath within the range of 0.2W5.0g/l at the time of carrying out zinc electroplating of steel sheet. Effect of preventing the pattern galling at the press time, is displayed because very dense zinc plating layer is formed by using the above plating bath. Accordingly, improvement of workability at the press processing of such steel sheet and that of quality of press forming product, are able to attain.
