Structural steel subjected to end-quench hardenability requirements are high-strength structural steels designed to have consistent and reliable hardenability. These steels undergo precise control of their chemical composition and heat treatment processes to ensure they meet specific hardenability criteria during the end-quench test. They are commonly used in applications requiring high strength and wear resistance, such as in the automotive, construction machinery, and heavy equipment manufacturing industries.
