Abstract

An aluminium-killed steel contg. 0.04-0.35% Ti with a Ti:C ration 4 and 0.005-0.15% sol. Al is hot rolled at 980-1100 degrees C with >1 pass to give a redn. in cross-section >28%, then rolled 980 degrees C to give a redn. over 50% with an end temp. of 730-880 degrees C. It is then cooled at 3-40 degrees C/sec. to the reeling temp. of 500-680 degrees C. The steel is heated >1200 degrees C prior to hot rolling. The steel compsn comprises 0.03-0.20% C, 0.8% max. Si, 0.9-2.5% Mn, 0.020% max. S, 0.008% max. N, and opt. 0.01-0.15% Zr, 0.005-0.10% La and Ce, 0.01-1.0% Nb, 0.01-0.10% V, 0.003% max B, and/or 0.5% max. each of Ni,Cr,Cu. The rolling technique rests on the basic that the coarse austenite grains formed on heating Ti steels can be recrystallised to fine grains by rolling >1100 degrees C and rolling below this temp. with >1 pass and a redn. >28% causes recrystallisation with a fine grained structure up to about 980 degrees C conferring high tensile strength with good cold toughness and cold working characteristics.
