During the first 9 months of 2010, prices ofhot-rolled steel were higher than those in 2009. The producer price index for steel mill products increased to 203 inMay 2010 from 153 in May 2009. Steel mill production capability utilization peaked at 75.4% in June 2010 from a lowof 40.8% in April 2009.Scrap prices fluctuated widely between about $290 <strong>and</strong> $367 per ton in 2010. Composite prices published by IronAge Scrap Price Bulletin for No. 1 Heavy Melting steel scrap delivered to purchasers in Chicago, IL, <strong>and</strong> Philadelphia<strong>and</strong> Pittsburgh, PA, averaged about $320 per ton during the first 8 months of 2010. As reported by Iron Age ScrapPrice Bulletin, the average price for nickel-bearing stainless steel scrap delivered to purchasers in Pittsburgh wasabout $2,273 per ton during the first 10 months of 2010, which was 45% higher than the 2009 average price of $1,502per ton. The prices fluctuated widely between a low of $1,711 per ton in January 2010 <strong>and</strong> a high of $2,724 per ton inApril <strong>and</strong> May 2010. Exports of ferrous scrap decreased in 2010 to an estimated 19 million tons from 22 million tonsduring 2009, mainly to China, the Republic of Korea, Taiwan, Malaysia, Turkey, <strong>and</strong> Canada, in descending order ofexport tonnage. Export scrap value increased from $7.1 billion in 2009 to an estimated $8.0 billion in 2010.North America has been experiencing a shortage of iron <strong>and</strong> steel scrap, owing to increased export dem<strong>and</strong>, primarilyfrom China, Turkey, <strong>and</strong> Canada. Even significantly increased prices for scrap have not led to an increase in scrapavailability, because almost all old scrap had been collected from farms, ranches, <strong>and</strong> other sources, <strong>and</strong> recessionhitconsumers have been keeping <strong>and</strong> repairing old appliances rather than disposing of them. Also, manufacturerswere decreasing production, thus producing little new scrap for the scrap market.World Mine Production <strong>and</strong> Reserves: Not applicable.World Resources: Not applicable.Substitutes: About 1.4 million tons of direct-reduced iron was used in the United States in 2009 as a substitute foriron <strong>and</strong> steel scrap, down from 2.0 million tons in 2008.e Estimated.

82IRON AND STEEL SLAG(Data in million metric tons unless otherwise noted)Domestic Production <strong>and</strong> Use: Iron <strong>and</strong> steel slags are coproducts of iron- <strong>and</strong> steelmaking <strong>and</strong> find a marketprimarily in the construction center. Although data on U.S. slag production are unavailable, the range of output isestimated as having increased by about 30% to about 11 to 15 million tons in 2010, owing to a restart of many of theiron <strong>and</strong> steel furnaces that had been idled at least part time in 2009. Better slag availability led to a modest increasein slag sales in 2010, although volumes remained constrained by continued low levels of construction spending. Anestimated 15 million tons of iron <strong>and</strong> steel slag, valued at about $290 million 1 (f.o.b. plant), was sold in 2010. Iron orblast furnace slag accounted for about 60% of the tonnage sold <strong>and</strong> had a value of about $250 million; nearly 85% ofthis value was granulated slag. Steel slag produced from basic oxygen <strong>and</strong> electric arc furnaces accounted for theremainder. 2 Slag was processed by nearly 30 companies servicing active iron <strong>and</strong>/or steel facilities or reprocessingold slag piles at about 120 sites in 32 States; included in this tally are a number of facilities that grind <strong>and</strong> sell groundgranulated blast furnace slag (GGBFS) based on imported unground feed.The prices listed in the table below are the weighted, rounded averages for iron <strong>and</strong> steel slags sold for a variety ofapplications. Actual prices per ton ranged widely in 2010 from about $0.20 for steel slags for some uses to about$100 for some GGBFS. The major uses of air-cooled iron slag <strong>and</strong> for steel slag are as aggregates for asphalticpaving, fill, <strong>and</strong> road bases <strong>and</strong> as a feed for cement kilns; air-cooled slag also is used as an aggregate for concrete.Nearly all GGBFS is used as a partial substitute for portl<strong>and</strong> cement in concrete mixes or in blended cements.Pelletized slag is generally used for lightweight aggregate but can be ground into material similar to GGBFS. Owing totheir low unit values, most slag types can be shipped by truck only over short distances, but rail <strong>and</strong> waterbornetransportation can be longer. Because of its much higher unit value, GGBFS can be shipped economically over longerdistances.Salient Statistics—United States: 2006 2007 2008 2009 2010 eProduction, marketed 1, 3 20.3 19.6 18.8 12.5 15.0Imports for consumption 4 1.6 1.9 1.3 1.3 1.5Exports 0.1 0.1 ( 5 ) ( 5 ) ( 5 )Consumption, apparent 4, 6 20.2 19.6 18.8 12.5 15.0Price average value, dollars per ton, f.o.b. plant 20.00 22.00 18.00 19.00 20.00Stocks, yearend NA NA NA NA NAEmployment, number e 2,500 2,200 2,100 2,000 2,100Net import reliance 7 as a percentage ofapparent consumption 8 9 7 10 10Recycling: Slag may be returned to the blast <strong>and</strong> steel furnaces as ferrous <strong>and</strong> flux feed, but data on these returnsare incomplete. Entrained metal, particularly in steel slag, is routinely recovered during slag processing for return tothe furnaces, but data on metal returns are unavailable.Import Sources (2006–09): Granulated blast furnace slag (mostly unground) is the dominant ferrous slag typeimported, but official import data show significant year-to-year variations in tonnage <strong>and</strong> unit value <strong>and</strong> commonlyinclude some shipments of industrial residues other than ferrous slags (such as fly ash, silica fume, cenospheres) orof slags of other metallurgical industries. Further, the official data in recent years appear to underrepresent true importlevels of granulated slag. Based on official data, the principal country sources for 2006–09 were Japan, 44%;Canada, 38%; Italy, 13%; South Africa, 4%; <strong>and</strong> other, 1%.Tariff: Item Number Normal Trade Relations12-31-10Granulated slag 2618.00.0000 Free.Slag, dross, scale, frommanufacture of iron <strong>and</strong> steel 2619.00.3000 Free.Depletion Allowance: Not applicable.Government Stockpile: None.Prepared by Hendrik G. van Oss [(703) 648-7712, hvanoss@usgs.gov, fax: (703) 648-7757]
