Semi-finished products are produced by the continuous casting of liquid steel or by rolling or forging of ingots (a primary solidification of liquid steel). Their chemistry is adjusted to meet specific physical property and grade requirements. Semi-Finished products are used in industry for the further production of finished steel products. Some examples of these products could be billets & slabs. Billets are generally used for making flat steel products by forging them in desired shapes and slabs are generally used in construction of heavy machinery or hot rolling them into flat products.
