For the sheet of deep drawing steel the required properties were found as follows ; (1) Low yield point and normal tensile strength and yet good ductility. (2) Negligible strain aging to get fine surface after drawing. From this point of view, the authors studied the proper temper rolling reduction ratios for the rimmed type steel sheet manufactured in the yawata steel Works. The authors performed investigations on the annealed coil sheet manufactured by the normal process. The tensile and Erichsen tests were made with various aging samples which were reduced down to various rolling ratios, and the stress-strain curves and the strain aging effects were obtained. The author made clear the proper reduction ratio for the temper rolling mill operation. According to the result of the experiment, the most proper ratio for the temper rolling was 0.8∿1.2%. If the drawing quality of the sheet was aimed, this range of the ratio should be extended to 0.5%. On the other hand, to secure fine surface quality of the sheet, it should be extended to 1.5%.
