HEAVY MELTING SCRAP (HMS1&2)

Heavy Melting Scrap (HMS) 

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 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).
Each grade guarantees a minimum piece thickness: at least 1/4 inch (6.3 mm) for HMS 1, and 1/8 in for HMS 2.

HMS 1&2 (80:20) and HMS1 (90:10):
HMS 1&2 (80:20) is the most traded grade of scrap metal globally. Since the yields around 20 tons in a 20 feet container, obviously the density of this grade is a bit lighter than HMS1&2 (90:10). Conforming to ISRI 200 to 206, this grade of scrap comes mostly from countries which are not industrialized as this will comprise of household scrap, demolition scrap and re-furbishing scrap. From recycled ship following kind of scrap comes:
Light Melting Scrap,
Heavy Melting Scrap,
Re-roll-able Plates from 6 mm to 40 mm,
Cast Iron Scrap,
MS Shafting : EX-18, EX-19, EX-21, EX-24 with hole & without hole.
