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.
Scrap Description: H.M.S. 1&2 (80/20) and H.M.S.1 (100%)
Scraps Specifications:
The scrap consists out of a mix of:
– Mill scrap (stampings, cuttings, bars, etc. ;),
– Industrial scrap (nuts, bolts, misc. pieces, etc.)
– Auto and truck frames and bodies
– Railroad scrap (wheels, axles, parts of locomotives and carriages, etc.)
– Ship scrap (fittings, plate pieces, parts, etc.)
– Construction scraps (plate, bars, angle pieces, rods, steel pipe, etc.)
– Miscellaneous commercial scrap (appliance casings, frames and parts, etc.)
Non-metal impurities total of 1% (one percent) or less.
All goods sold by the Seller will also be totally free from any types of radiation, bombs, arms and ammunition, mines, shell, cartridges, sealed containers, gas cylinders, explosive shells or explosive materials in any form either used or otherwise as per the specification below.
Steel scrap shall be considered free of alloys when the residual alloying elements do not exceed the following percentages:
– Nickel 0.45%
– Chromium 0.20%
– Molybdenum 0.10%
– Manganese 1.65%
The combined residuals other than manganese shall not exceed a total of 0.60%.
