Four hot rolled steel grades were produced by the thin slab casting
with direct rolling technology at Acciaieria Arvedi S.p.A. (Cremona)
and were coiled at two different temperatures. The steels are featured
by different chemical compositions: one is low carbon Al killed
and three are high strength low alloy (HSLA) characterized by the
presence of Nb, V. The aim of the study is to investigate the influence
of the different coiling temperature on the mechanical and formability
properties as a function of the different chemical compositions
in order to exploit the potential of the plant. The results about the
induced strain aging appear interesting and are presented in this
paper.
