A new coating steel such as a resin coated steel has been applying for various home appliances. The resin coated steel has different friction coefficients between the front and the back face. In this study, influence on formability by the different friction coefficients is investigated using numerical simulation.

Steel sheets with different coating layers on front and back such as Black Resin Coated Steel and UV Curable Resin Coated Steel have been developed to obtain high functionality of steel material. The formability of the steel sheets is changed because these steel sheets have different friction coefficients necessarily. In this paper, tensile, friction and FLD tests of the steel sheet with different coating layers on the each side have been performed and the results have been discussed to verify how to change the formability of the steel sheets.
