Questi acciai sono caratterizzati da limiti massimi di snervamento e di rottura ed allungamenti minimi garantiti. Sono classificati in ordine crescente di formabilit\u00e0 e possono pertanto essere utilizzati nelle diverse lavorazioni a freddo, dagli stampaggi meno critici (DC01) fino alle pi\u00f9 profonde imbutiture (DC05 e DC06). Vengono prodotti in ricottura statica o in ricottura continua. Possono essere forniti con diversi requisiti di aspetto superficiale, finitura superficiale e protezione superficiale.<\/p>\n<\/td>\n<\/tr>\n<\/tbody>\n<\/table>\n<\/div>\n<\/div>
