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 galvanised and blackened steel, whereas HMS 2 does. This kind of scrap may include automobile parts and cast iron.
Plates and Structural: Re-rollable scrap is a steel scrap metal that is already in such a condition that it is suitable for another application through rolling it into a saleable product.This differs from the more common processes seen in scrap recycling where the metal undergoes melting, casting and rolling. Re-rolling is more commonly used in emerging economies rather than in industrialised countries. Cut structural and plate scrap, 5 feet and under and 18 inches in width.
Cast iron scrap is a variety of metal scrap that is high in carbon. Several products and structures around us use carbon steel such as columns, pipes, plates, and/ or castings of miscellaneous nature. Must not be over 24 x 30 inches in dimension and no piece to weigh over 150 pounds.Cast iron is a comparatively brittle when compared to mild steel products.
Busheling bundles has one of the highest recovery rates when charged in a furnace. It consists of clean steel scrap of a maximum size of 2 feet by 5 feet. It includes new factory busheling (for example, sheet clippings, stampings, etc.). Busheling bundles are required to be oil free and free of any coating or galvanisation.
Shredded steel scrap or Shredded 211 is a homogeneous iron and steel scrap magnetically separated, originating from automobiles, unprepared No. 1 and No. 2 steel, miscellaneous baling and sheet scrap. This scrap is then processed through shredders that size the scrap to pieces that are 3 to 4 inches in length and 2-3 inches in width. This scrap is of the correct density if it is measured to have an average density 70 pounds per cubic foot.
Wrought iron or steel scrap, black or galvanized, 1/8 inch and over in thickness, compressed to charging box size and weighing not less than 75 pounds per cubic foot. Auto body and fender stock, burnt or hand stripped, may constitute a maximum of 60 percent by weight. (This percent based on makeup of auto body, chassis, driveshafts, and bumpers.) Free of all coated material, except as found on automobiles.
Mild steel turnings and iron borings are a result of the manufacturing and machining of iron and steel parts, components and articles. It is clean steel or wrought iron turnings, free of nonferrous metals or excessive oil. Turnings and borings come in two physical forms; loose, or in pressed briquettes.
