Ferrous Materials

HMS stands for heavy melting scrap, Heavy melting steel (HMS) or heavy melting scrap 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. HMS 1 is the term for heavier scrap which has a density of at least 0.7 tons per cubic meter, whereas HMS 2 would be lighter steel scrap such as thin wall tubing, sheet scrap less than 3.2mm thick and so on. HMS is typically traded as a blend of 1 and 2, either a premium blend (80/20) or lower grade mixes (70/30) and (60/40). For example, HMS 1 and 2 (80/20) should consist of HMS 1 and 2 in the ratio of 80% (HMS 1) and 20% (HMS 2).
