The Manufacture of High Strength, Vanadium-Containing Steels by Thin Slab Casting
Abstract:
The effects of microalloying with vanadium, niobium, titanium and molybdenum on the manufacture and properties of hot rolled coil, produced by simulating the thin slab casting process have been studied. It has been demonstrated that vanadium-containing steels should be less prone to exhibit transverse cracking during continuous casting than niobium-containing steels. It has also been shown that steels alloyed with vanadium alone are capable of achieving yield strengths up to and including 550MPa (80ksi), depending on the levels of vanadium and nitrogen used. The potential for further increase in yield strength to 700MPa (1 02ksi), has also been established. The mechanisms controlled both the cracking behaviour and mechanical properties are illustrated and discussed.
