What is Harden-Ability Structural Steel Round Bar
High harden-ability structural steel round bar is mainly composed of iron, carbon and various alloyed elements (such as chromium, nickel, molybdenum, vanadium, etc.). The addition of these alloying elements not only improves the hardenability of steel, but also enhances its strength, toughness and wear resistance. Different alloying element proportions and heat treatment processes can produce steel rods with different properties to meet the needs of different application scenarios.
