Abstract

Non-ageing steel contains (%) 0.0025-0.015 C, 0.02-0.3 Nb, 0.1-0.6 Mn, =0.035 S, =0.01 O2, =0.012 N, =0.045 Al. The Nb/C ratio is between 8:1 and 12:1, such taht all the Nb is present as NbC. The Mn/S ratio is 7:1 to reduce the number of harmful inclusions. N is stabilised either by Al or Ti prior to the addition of Nb to the melt. The steel has higher ductility and formability than current non-ageing steels, and is suitable for most deep drawing operations.
