The Masters Mind inc. sources Scrap metal globally from various suppliers to meet the Growing demands from Domestic & International sources.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. ISRI 200 (HMS 1): Wrought iron or steel scrap 1.4 inch and larger in thickness. ISRI 201 (HMS 1): 1/4 " thick except pieces must be smaller than 36 X18 in.ISRI 202 (HMS 1): 1/4 " thick except pieces must be smaller than 60X18 in.ISRI 203 (HMS 2): Wrought iron or steel scrap, black and galvanized, 1/8 inch and larger in thickness.ISRI 204 (HMS 2): wrought iron, Galvanized 1/8 " thick except pieces [1]must be smaller than 36 X 18 in.ISRI 205 (HMS 2): galvanized 1/8 " thick 204 except it may contain automotive scrap except for thin gauge material.ISRI 206 (HMS 2): 1/8 " thick except pieces must be smaller than 60x18 in. HMS 1 and 2 are widely traded, particularly in the western hemisphere. Both HMS 1 and 2 comprise obsolete scrap only. That is iron and steel recovered from items demolished or dismantled at the end of their life. This density, sizing and preparation makes for efficient furnace operation by minimizing the time to charge enough scrap for a full melt. In contrast, thin mixed scrap greatly increases charging time, cutting furnace productivity.Variations on maximum piece size are covered by ISRI codes. HMS is usually traded as a blend of 1 and 2, either a premium blend (80:20) or lower grade mixes (70:30) & 60-40
