Alloy structural steels are widely used materials in engineering. Based on their properties and applications, they are mainly divided into two categories: quenched and tempered structural steel and surface-hardened structural steel. Quenched and tempered structural steel achieves good comprehensive performance through heat treatment and is suitable for manufacturing various important structural parts. Surface-hardened structural steel forms a high-hardness, wear-resistant, and corrosion-resistant hardened layer on the surface of the steel through special processing, making it suitable for applications subject to friction and wear. These two types of alloy structural steels each have their advantages and are widely used in bridges, buildings, machinery, and other fields, providing a solid material foundation for modern engineering construction. With continuous technological advancements, the performance of alloy structural steels continues to improve, providing stronger support for development in various fields.
