Abstract
The present invention provides a tin blackplate for processing and a method for manufacturing the same. The tin blackplate according to an exemplary embodiment of the present invention comprises: in % by weight, 0.0005 to 0.005% of carbon (C), 0.15 to 0.60% of manganese (Mn), 0.01 to 0.06% of aluminum (Al), 0.0005 to 0.004% of nitrogen (N), 0.0005 to 0.003% of boron (B), 0.01 to 0.035% of titanium (Ti), and the balance being iron (Fe) and inevitable impurities, and satisfies the following Formula 1. 4.8≤([Ti]+[Al])/[N]−[B]≤12.5 [Equation 1] In this case, in Equation 1, [Ti], [Al], [N], and [B] mean each value obtained by dividing the content (% by weight) of Ti, Al, N, and B in the blackplate by each atomic weight thereof.
