摘要： A metallurgical product, made of carbon steel and to be galvanized, which is in the form of a strip or of a sheet obtained from a continuously cast intermediate product having the following composition by weight: 0.0005%nullCnull0.15%; 0.08%nullMnnull2%; Sinull0.040%; Altotalnull0.010%; Alsolublenull0.004%; 0.0050%nullOtotalnull0.0500%; Pnull0.20%; Snull0.10%; each of Cu, Cr, Ni, Mo, W, Conull1%; each of Ti, Nb, V, Zrnull0.5%; each of Sn, Sb, Asnull0.1%; Bnull0.1%; Nnull0.0400%; and the remainder being iron and impurities. Also, a process for obtaining a metallurgical intermediate product, which includes: producing in a ladle a liquid steel the composition of which is as above, and in which the dissolved oxygen content is maintained between 0.0050 and 0.0500% by the establishment of a chemical equilibrium between the metal and the ladle slag; and casting said steel on a continuous casting machine.
