The objective of this U.S. Bureau of Mines study is to calculate an accurate, reliable estimate of chromium and nickel content of stainless and heat-resisting steel produced in the United States. The columbium, manganese, molybdenum, titanium, tungsten, and vanadium contents of this steel are also calculated. Such contents are required for estimating the quantity of alloying element recovered from recycled stainless steel and consumed by market sectors. In this investigation, the elemental fraction of stainless and heat-resisting steel was calculated as the ratio of the weight of element contained in stainless steel to the weight of stainless steel produced. The elemental fraction has been calculated as a time-averaged, grade-averaged value. The elemental fraction was averaged from 1962 through 1983, and averaged over the grades for which production was reported by the American Iron and Steel Institute during that time period. The 1962-83 average elemental fraction of U.S.-produced stainless and heat-resisting steel was calculated for chromium to be about 0.17 +/- 0.01; Columbium 0.00014 +/- 0.00003; Manganese, 0.015 +/- 0.005; Molybdenum, 0.004 +/- 0.001; Nickel, 0.07 +/- 0.01; Silicon, 0.009 +/- 0.001; Titanium, 0.0004 +/- 0.0001; Tungsten, 0.0001 +/- 0.00003; and vanadium, 0.00003 +/- 0.00001.
