1. HEAVY MELTING STEEL (HMS)
Heavy melting steel (HMS) or heavy melting scrap is a designation for recyclable steel and wrought iron. It is broken up into two major categories: HMS 1 and HMS 2, where HMS 1 does not contain galvanized and blackened steel, whereas HMS 2 does.
2. SHREDDED
Shredded scrap is a large part of the recycling industry and can be utilized in multiple circumstances. The shredded scrap grade consists of homogeneous iron and steel scrap, which is magnetically separated, originating from automobiles, including but not limited to unprepared no. 1 and no. 2 steel, miscellaneous baling, and sheet scrap.
3. CAST IRON
Cast iron is an iron or a ferrous alloy which has been heated until it liquefies, and is then poured into a mould to solidify. It is usually made from pig iron. The alloy constituents affect its colour when fractured: white cast iron has carbide impurities which allow cracks to pass straight through. Grey cast iron has graphitic flakes which deflect a passing crack and initiate countless new cracks as the material breaks
4. RE-ROLLABLE
Re-rollable scrap is a steel scrap metal that is already in such a condition that it is suitable for another application through rolling it into a saleable product.This differs from the more common processes seen in scrap recycling where the metal undergoes melting, casting and rolling. Re-rolling is more commonly used in emerging economies rather than in industrialised countries.
