Abstract

1,174,414. Steel. YAWATA IRON & STEEL CO. Ltd. Dec. 19, 1966 [Dec.18, 1965], No .56710/66. Heading C7A. A semi-killed steel has the following percentage composition: - C less than 0À85 Si 0À02 - 0À09 Cr 0À42 - 2 Mn 0À3 - 1À25 Fe and impurities - balance with the provisos that Cr > Mn, and Cr + Mn < 2À5. The steel may also contain (a) one or more of Cu, Ni, Mo, W and Co in a total amount not more than 2%, or less than 1% if only one element is added; and (b) one or more of Nb, Ta, As, V, P, S, Sb and Pb in a total amount not more than 0À2%, or not more than 0À1% if only one element is added. If elements from both groups (a) and (b) are present, the sum of (a) and 10 times (b) should be less than 2%.
