In 1963, the Swedish Noren first proposed the definition of microalloyed steel, namely the Mn-bearing alloy steel or low-alloyed steel with the addition of a small amount of alloying elements. The alloying element has a significant effect on one or several properties of steel, and its amount is smaller than that of traditional alloying element in steel by 1–2 orders of magnitude (Noren in Special report on Columbium as a microalloying element in steel and its effect on welding technology. Ship Structure Committee, Washington, 1963, [1]). This definition has been widely adopted around the world and has been in use up to now. Titanium microalloyed steel is such one kind of microalloyed steel, and titanium is a typical microalloying element. There are other similar elements, such as niobium, vanadium and boron.
