In recent years, the 3rd generation of advanced high-strength steels (AHSS) has been developed for automotive sheet applications using quenching and partitioning (Q&P) as one of the heat treatments, developing a microstructure of martensite and retained austenite (RA). There is interest in exploring the application of a Q&P process to low-alloy plate steel because a microstructure of martensite and RA may have enhanced wear resistance and toughness as compared to tempered martensite microstructures generated by traditional quench and temper (Q&T) processes. In this work, Q&P and Q&T heat treatments are applied to 18 mm steel plates with nominal composition 0.2C-1.5Si-1.5Mn-0.4Cr-0.25Mo to obtain a bulk hardness >400 HBW. The conditions are compared via microstructural characterization and mechanical properties.
