| description | A machine structural steel being free of lead, excellent in machinability and reduced in strength anisotropy, which has the following composition based on weight; C: 0.10 to 0.65 %, Si: 0.03 to 1.00 %, Mn: 0.30 to 2.50 %, S: 0.03 to 0.35 %, Cr: 0.1 to 2.0 %, Al: less than 0.010 %, Ca: 0.0005 to 0.020 %, Mg: 0.0003 to 0.020 %, O: less than 20 ppm, balance: Fe and inevitable impurities. The structural steel contains no Pb and has properties which are same as or superior to those of a conventional free cutting steel containing Pb.
L'invention concerne un acier structural sans plomb pour construction mécanique présentant une excellente usinabilité et une anisotropie de résistance réduite. Cet acier présente la composition suivante, sur la base du poids: C: entre 0,10 et 0,65 %, Si: entre 0,03 et 1,00 %, Mn: entre 0,30 et 2,5 %, S: entre 0,03 et 0,35 %, Cr: entre 0,1 et 2,0 %, Al: moins de 0,010 %, Ca: entre 0,0005 et 0,020 %, Mg: entre 0,0003 et 0,020 %, O: moins de 20 ppm, le reste se composant de Fe et des impuretés inévitables. Cet acier structural ne contient pas de Pb et présente des propriétés identiques ou supérieures à celles d'un acier de décolletage classique contenant du Pb. |
