  327Ferroalloys 
By Frederick J. Schottman1 
 Production of ferroalloys in the United States increased in 1979 after declining
each year from 1973 through 1978. Prices were generally higher in 1978 and
1979 owing to higher production costs and stronger markets. 
 Consumption of the bulk ferroalloys of silicon and manganese increased in
1978 and weakened in 1979 as total steel and cast iron production fell late
in the year. Consumption of most ferroalloys used predomi 
nantly in alloy steels increased in both 1978 and 1979. 
 Exports of ferroalloys rose significantly in 1978 and 1979 but remained
small compared with imports. Imports increased by about a fifth in 1978 but
only slightly in 1979. 
 Legislation and Government Pro~grams—Eight ferroalloys were included
in Government stockpiles. There were no changes in the inventories held during
1978 and 1979.
