This work presents a DP800 automotive steel produced using rapid alloy prototyping with varying levels of copper, tin and nickel, which are three common residual elements introduced into new steels by recycling steel scrap. Manufacturers have increasing responsibilities to be environmentally responsible and although recycling is a huge part of this, it is not without issue; residual elements can be detrimental to the mechanical properties of the steel. Here, the mechanical impacts of higher residual elements are presented and compared to industrially produced versions of the same grade to predict what could be expected if the scrap content in new steel were to be increased. These results aim to show that higher levels of scrap can be used without comprising the quality of the steel. This move would have the potential to preserve valuable iron ore, lime and coal resources, reduce water and energy use, and lower carbon dioxide emissions.
