The process was originally used solely for making high quality steel, such as those used for machine tools and spring steel, as it gave more precise control over the composition. Today, however, it is also employed in making more widely used steels, including alloy and stainless grades as well as some special carbon and low-alloy steels.

Step 2 - Steel making The steel making process is shown in Figure 2. Vanadium recovery Before conversion into steel, vanadium is recovered from the molten iron. This is done firstly because of the value of the vanadium rich slag produced 15 vanadium as V2O5 and secondly because a high vanadium content can make the steel too hard.
