Development of Advanced High-Strength Steels for Automobile Applications

Stelco has developed a suite of Advanced High-Strength Steels (AHSS) grades with tensile strength greater than 1000 MPa to meet standard automotive specifications and for unique customer requirements. These grades were optimized by correlating chemical composition and processing parameters with microstructures and mechanical properties . Dual-Phase 980 (Stelco trademarked STELMAX TM 980DP), Multiphase 1180 (STELMAX TM 1180MP), Martensitic 1300 (STELMAX TM 1300M) and 1500 (STELMAX TM 1500M) products met strength and formability requirements with excellent flatness and consistent mechanical properties across the entire strip length and width by using hydrogen quench continuous annealing technology.
