Advanced High Strength Steel
CR(Advanced High Strength Steel)
Cold-rolled steel products are widely used in various applications, ranging from household appliances such as automobiles, washing machines, and refrigerators to industrial machinery and various construction materials. Furthermore, new demands for high-value-added products, such as steel cans and steel houses, continue to be created, leading to an expansion of development and production in this field.
Advanced High Strength Steel (AHSS) is a type of transformation-hardened steel that uses low-temperature phase transformation to enhance its strength. It includes several varieties such as Dual Phase (DP) steel, Transformation-Induced Plasticity (TRIP) steel, Extra Formable (XF) steel, Twinning-Induced Plasticity (TWIP) steel, Complex Phase (CP) steel, Martensitic (Mart) Steel, and Ferrite and Bainite (FB) steel.
Among them, steels with a tensile strength of 1GPa or higher are referred to as Giga steel.
