In response to the demanding requirements of different sectors, such as construction, transportation, energy, manufacturing, and mining, new generations of microalloyed steels are being developed and brought to market. The addition of microalloying elements, such as niobium, vanadium, titanium, boron, and/or molybdenum, has become a key tool in the steel industry to reach economically-viable grades with increasingly higher mechanical strength, toughness, good formability, and weldable products. The challenges that microalloying steel production faces can be solved with a deeper understanding of the effects that these microalloying additions and combinations of them have during the different steps of the steelmaking process.

This is a collection of papers presented at the joint conference of the 7th International Conference on High Strength Low Alloy Steels (HSLA Steels 2015), the International Conference on Microalloying 2015 (Microalloying 2015), and the International Conference on Offshore Engineering Steels 2015 (OES 2015). The papers focus on the exchange of the latest scientific and technological progresses on HSLA steels, microalloying steels, and offshore engineering steels over the past decades. The contributions are intended to strengthen cooperation between universities and research institutes, and iron and steel companies and users, and promote the further development in the fields all over the world.
