These elements are controlled to ensure proper hardenability, strength, and weldability. For instance, adding grain-refining elements such as vanadium (V), niobium (Nb), and titanium (Ti) helps improve toughness. The total content of these elements must not exceed 0.10%, 0.06%, and 0.20%, respectively, unless aluminum (Al) is added at a minimum of 0.015% .
