HMS 1 and HMS 2

Steel

HMS stands for heavy melting scrap, and this is composed of two different categories. The main difference between the two is that HMS1 does not contain galvanized and blackened steel unlike HMS2. Because both grades guarantee a minimum piece thickness – at least 1/4inch (6.3mm) for HMS 1, and 1/8in for HMS 2 – consignments have a high density. Both also have defined maximum dimensions (usually 60in x 24in), and should be prepared to facilitate handling and charging to a furnace. This density, sizing and preparation makes for efficient furnace operation by minimising the time to charge enough scrap for a full melt. In contrast, thin mixed scrap greatly increases charging time, cutting furnace productivity.
