 The steel output for 1941 includes 8,174,961 net tons of alloy-steel ingots
and castings, which represent 10 percent of the total. This figure includes
steels in which the minimum of the range specified in any of the elements
named exceeds the following percentages: Nickel, 0.40 percent; chromium,
0.30 percent; copper, 0.50 percent; manganese, 1.65 percent; silicon, 0.50
percent; molybdenum, 0.10 percent; vanadium, tungsten, cobalt, titanium,
and zirconium, any percentage. The output of alloy steels in 1941 increased
65 percent and that of total steel 24 percent over 1940. Of the total alloy-steel
output in 1941, 65 percent came from basic open hearths, 5 percent from acid
open hearths, 30 percent from electric furnaces, 933 tons from crucible furnaces,
and 3,890 tons from bessemer furnaces.
