IRON-ZINC ALLOY ELECTROPLATED STEEL PLATE FOR PRESSING WITH SUPERIOR RESISTANCE TO DAMAGE OF FILM AND SUPERIOR PROPERTY OF PREVENTING STICKING OF FILM TO PRESSING DIE

摘要

PURPOSE:To obtain a plated steel plate for pressing with improved resistance to the damage of the film and an improved property of preventing the sticking of the film to pressing dies by specifying the Fe content of the film of an Fe-Zn alloy electroplated steel plate. CONSTITUTION:The Fe content of the plated film of an Fe-Zn alloy plated steel plate is restricted to 3-30wt% to improve the hardness and crystal structure of the film. Accordingly, the damage of the film as well as the powdering can be relieved during pressing, and the sticking of the film to pressing dies is also reduced. This Fe-Zn alloy plated steel plate for pressing has the advantages of both of a zinc plated steel plate and a galvanized steel plate.
