Abstract
L'invenzione ha come oggetto acciai di composizioni particolari che, grazie al loro tenore in zolfo e alla composizione delle inclusioni ossidate, sono particolarmente adatti per la lavorazione in barra o a troncatura e per la lavorazione a grande velocità mediante utensili di carburo o di ceramica.Gli acciai contengono in % in peso:C - da 0,05 a 0,45%Mn -da 0,80 a 1,65%Si - da 0,10 a 0,35%P - massimo 0,030%S - da 0,50 e 0,2 %e le loro inclusioni ossidate hanno come composizioni, in % in peso:Al2O3 -da 15 a 50%SiO2 -da 20 a 60% CaO + MnO - da 15 a 50%Questi acciai conservano, nonostante la presenza di zolfo, buone caratteristiche meccaniche.The invention relates to steels of particular compositions which, thanks to their sulfur content and the composition of oxidized inclusions, are particularly suitable for bar or parting and for high speed machining with carbide or ceramic tools. The steels contain in% by weight: C - from 0.05 to 0.45% Mn - from 0.80 to 1.65% Si - from 0.10 to 0.35% P - maximum 0.030% S - from 0 , 50 and 0.2% and their oxidized inclusions have as compositions, in weight%: Al2O3 - from 15 to 50% SiO2 - from 20 to 60% CaO + MnO - from 15 to 50% These steels retain, despite the presence of sulfur, good mechanical characteristics.
