U.S. Raw Steel Production Slips in September

Written by Brett Linton

U.S. raw steel production in September fell 5.3 percent to 7,720,237 net tons, reports the American Iron and Steel Institute in Washington. September production is below the 2019 average of 8,099,797 tons and down 3.5 percent compared to the same month last year.

Broken down by production method, 5,349,165 tons (69.3 percent) were produced by electric arc furnaces (EAFs) and 2,371,072 tons (30.7 percent) were produced by blast furnaces.

September production was 432,559 tons lower than August, and 276,763 tons lower than the same month last year. AISI’s monthly estimates are different than the weekly estimates SMU reports each Tuesday; the monthly estimates are based on over 75 percent of the domestic mills reporting versus only 50 percent reporting for the weekly estimates.

The mill capacity utilization rate for September averaged 77.4 percent, down from 79.1 percent in August, and down from 79.6 percent one year ago. The yearly capacity utilization rate has been adjusted down to 80.3 percent, still up from 77.5 percent compared to the same period last year.

The chart below shows total monthly steel production (blue) broken down by electric arc furnace production (green) and blast furnace production (red).
