Pb-8mass%Sn coated steel sheet (which is known as terne sheet) has been widely used for automotive fuel tanks because of its well-balanced properties during tank manufacturing and durability under severe corrosion circumstances. Reduction of lead has become an urgent topic in discussions on ways to reduce the burden on the environment. Nippon Steel Corporation has developed alternative steel sheet. They are hot dip Sn-Zn alloy coated steel sheet and GI-Ni double-layered steel sheet, which has electro galvanized .Ni on hot dip Zn coatings (GI). Both of them are capable of providing: (1) good internal corrosion resistance, (2) good external corrosion resistance, (3) good solderability and resistance weldability, and (4) good press formability. They have been already adopted by many automobile producers and significantly reduced the use of lead for automobiles.
