Assessment 2 – 40580/02 1a) Plain carbon steel is essentially an alloy of iron and carbon which also contains manganese and a variety of residual elements. These residual elements were either present within the raw materials used in the production process e.g. iron ore and scrap steel additions‚ or they were added in the production process for a specific purpose‚ e.g. deoxidization by means of silicon or aluminium. Hence they are called residual elements to distinguish them from alloying
