This report shows the results of weldability, contact resistance, rust resistance, corrosion behavior and lacquer adhesion on the Lightly Tin Coated Steel (LTS) having 0.3 and 0.6g/m2 of tin compared with tinplate having 1.28g/m2 of tin and Tin Free Steel. Preliminary test on the iron-tin alloy comand there were some differences in shape and size of the alloy. Weldability at the welding speed of 30m/min and 48m/min was improved with increase of tin coating weight; Available current range of

Contact resistance of 0. 6g/m2 LTS was almost similar to that of tinplate, however fully alloyed LTS had relatively high resitance. Polarization characteristics of iron, tin, iron-tin alloy and metallic chromium indicated that in tomato juice, corrosion behavior of LTS was similar to that of tinplate, however underfilm corrosion of LTS was less than that of tinplate and iron pick up tendency of LTS was also less than TFS. Lacquer adhesion of fully alloyed LTS was better than that of tinplate and other LTS.
