Process definition of hardened boron steel grades in aspect of anticorrosion

Abstract [en]

Hardened Boron Steel is today used on most automobiles as safety components. For a few years now the competition has increased in this area and in order to sell products they have to be cheap and provide good corrosion protection. The problem areas with the hardened boron steel are the hardening process and the corrosion protection. In the hardening process scaling is formed when hot boron steel reacts with the oxygen in the air. Boron steel also lack the Zinc coating that the HSS steels have for the corrosion protection. To solve these two problems the steel makers developed pre-coated boron steel grades. This master thesis will investigate different boron steel grades and see how they fit into the processes at Linde + Wiemann GmbH KG and if they can provide the required corrosion properties. Linde + Wiemann GmbH KG is an international company which primary focus on manufacturing of car components. In 2007 L+W bought the Swedish company Accra Teknik AB in Ă–jebyn to be able to offer manufacturing of hardened boron steel components.
