Abstract��The influence of various annealing temperatures on mechanical properties of 0.18 mm tinplate was investigated by uniaxial tensile tests. The aging resistance properties of tinplate were studied using X-ray photoelectron spectrometer (XPS). The results showed that when the annealing temperature increased from 660 �� to 700 �棬 the yield strength decreased from 295 MPa to 274 MPa�� the tensile strength decreased from 371 MPa to 352 MPa�� the percentage elongation after fracture increased from 24.2% to 27.8%�� the grain size increased from 5.4 ��m to 5.8 ��m�� the surface Rockwell hardness decreased from 57.9 HR 30T to 54.5 HR 30T�� the relative mass content of solid solution C decreased from 90.5% to 88.1%�� and the relative mass content of solid solution N decreased from 88.7% to 83.7%. The tested sheet exhibited good plasticity�� lower surface Rockwell hardness�� as well as content of solid solution C and N were more accordant with the national standard when the annealing temperature is 700 ��.
