PRODUCTION OF IRON AND STEEL POWDERS

by Höganäs could readily be comminuted to iron powder. Production of iron powder started on a small scale at Höganäs in Sweden between 1937 and 1939, and regular shipments were made to the USA. These early grades of sponge iron powder were unannealed, containing up to 2% of reducible oxygen (H 2-loss) and up to 0.15% of carbon. Consequently, their compressibility was poor, and the ...
