Increasing rates of plastic production by injection moulding and production of larger parts have required larger die blocks of steel. Microalloying of vanadium as a substitute of nickel has induced hardenability improvement to increase size of these dies. This has referred to that nickel substituted by vanadium has been future reactor steel. Microalloying of thin slab castings by V, Ti, Nb and Zr have changed microstructure and mechanical properties in final products, e.g. stripes. Strategically this has referred to reduce coarse grained precipitation those have been formed during solidification and has not been dissolved at any greater austenitization temperature. Thin slab direct charge (TSDC) vanadium microalloyed steel has been standardized for optimization of properties and cost benefits in manufacture, e.g. compact strip processing. Investigation of yield strength (YS) in high strength low alloy (HSLA) - vanadium (V) steel have been estimated to range within 78 to 82 Knops per square inches (ksi) for cases of long span truss members. Conservative prediction of steel joist institute (SJI) has been referred not to exceed 50 ksi in long span steel joists and deep long span steel joists.
