There is presently a strong interest in using as-hot rolled steels in automotive and mechanical applications is place of the quenched and tempered steels. This because of the inherent metallurgical disadvantages associated with the latter, such as retained austenite, residual stresses quench-cracking and distortion. Additionally, hot rolled steels are likely to be cost effective and energy efficient, in that the additional processing through the conventional heat treatment system is eliminated. Increasing the strength of steel allows reducing the weight of a construction the knowledge about structure-property relations ship and the installation of modern facilities in steel making and rolling brought up a steady optimization of AHSS, allowing safe constructions under hostile environment with economic processes. Mobarakeh Steel has initiated the trial production of hot-rolled AHSS steels, with the utilization of the latest technologies in production trends and suitable design, focusing on the following objectives: 1) reduce Auto body weight up to 36%; 2) utilize the latest technologies; 3) achieve satisfactory performance of auto body during accidents; 4) decrease fuel consumption; 5) prevent environmental pollution. In this study, efforts are made to present the chemical analysis and mechanical properties of the coils produced in the trial running in addition to the characteristics of AHSS in relation to the optimization of strength, the effective thickness reduction of truck weight and fuel consumption reduction. The major impact was to lower the amount of inclusions and the carbon content well below the 0.09% level. The good experience obtained in the last decades of this century to the benefit of the steel users, the world economy and the ecology. It is worth quoting that HLE advanced high strength steels are applied for the production of various parts such as chassis, top ends supports, brake pedal main part, brake support D and J flanges.
