Abstract

본 발명은 내식성 및 내연료성이 우수한 Pb-Sn합금 도금강판에 관한 것으로서, 가공시, 윤활성, 용접성, 납땜성을 유지하면서 Pb-Sn 합금 도금층에 존재하는 기공부의 부식을 억제시켜 내식성, 가솔린 및 알콜혼합연료에 대한 우수한 내연료성을 갖는 강판을 경제적으로 제조할 수 있게 하는데 그 목적이 있다.The present invention relates to a Pb-Sn alloy plated steel sheet excellent in corrosion resistance and fuel resistance, and suppresses corrosion of pores in the Pb-Sn alloy plating layer while maintaining lubricity, weldability, and solderability during processing. And it is an object to be able to economically produce a steel sheet having excellent fuel resistance to the alcohol mixed fuel.

본 발명은 상기 목적을 실현하기 위하여 강판의 표면에 도금되는 도금층을 하층의 Pb-Sn 합금 도금층과 상층의 Pb-Sn 합금 도금층으로 된 이층 도금층으로 형성하되, 상기 하층의 Pb-Sn합금 도금층은 중량퍼센트로 2∼25％ 범위의 Sn을 함유하고 강판면적당 5∼100g/㎡ 범위의 부착량으로 도금되고, 상기 상층의 Pb-Sn합금 도금층은 중량퍼센트로 25∼70％ 범위의 Sn이 함유되고 강판면적당 1∼10g/㎡ 범위의 부착량으로 도금됨을 특징으로 한다.In order to achieve the above object, the present invention is to form a plating layer to be plated on the surface of the steel sheet as a two-layer plating layer consisting of a Pb-Sn alloy plating layer of the lower layer and a Pb-Sn alloy plating layer of the upper layer, the Pb-Sn alloy plating layer of the lower layer It contains Sn in the range of 2 to 25% by weight and is plated in the adhesion amount in the range of 5 to 100 g / m 2 per steel plate area, and the upper Pb-Sn alloy plating layer contains Sn in the range of 25 to 70% by weight and It is characterized by being plated with an adhesion amount in the range of 1 to 10 g / m 2.
