Estimates are published for industries (1) which consumed at least 2,500 tons of alloy and stainless steel in 1951 and 1950, and 5,000 tons in 1949, and (2) for which the standard error of estimate for the quantity figures is 15 percent or less. Unpublished estimates, including those which can be derived by subtraction, may have standard errors considerably in excess of the published data. Data shown for 1951 by specific 4-digit industry include both alloy and stainless steel purchases and interplant transfers, and alloy and stainless steel produced and consumed in the same establishment; 1950 and 1949 data presented by specific 4-digit industry exclude tonnages of alloy and stainless steel produced and consumed in the same establishment. The total tonnages of alloy and stainless steel produced and consumed in the same establishment in 1950 and 1949 are withheld because the estimates did not meet publication standards. However, it is estimated that the total tomages produced and consumed in all industries combined did not exceed 2 percent of the tonnage purchased or received through transfer in either 1950 or 1949. Those industries where alloy and stainless steel produced and consumed in the same establishment during 1949 and 1950 made up a substantial percent (5 percent or more) of the total alloy and stainless steel consumption of the industry have been footnoted for 1951 to indicate the approximate range of the percentage which alloy and stainless steel produced and consumed in the same establishment bears to total alloy and stainless steel consumption in the industry. Industry group totals (2-digit and 3-digit) include only the estimates for these industries for which data on consumption of alloy and stainless steel were collected in the 4 years.
