Description
Summary:One of the essential branches of today's engineering production involves the production of sheet stock by rolling. In the automotive industry is used the majority of steel sheet stock. In recent decades, this sector has been striving to reduce vehicle emissions. One of the available solutions involves the use of advanced high-strength steels whose chemical composition and strengthening mechanisms make it possible to build the car body with thinner sheet blanks than before. For rolling trials in which ingots were converted into 1.8 mm sheet by combined hot and cold rolling were used two advanced high-strength steels containing 0.2 wt. % carbon and additions of manganese, silicon and different levels of aluminium. This procedure was found to produce strengths in excess of 1000 MPa combined elongation of more than 15 %.
