PRODUCTION OF IRON AND STEEL POWDERS

account for more than 90% of the world production of iron and steel powders, viz. the Höganäs sponge-iron process and the water-atomizing process. The former process is based on reduction of iron ore, yielding a highly porous sponge-iron which subsequently is comminuted to powder. The latter process is based on atomization of a stream of liquid iron (or steel) by means of a jet of ...

ORB: Iron and Steel Production in the Middle Ages

Carbon is the major variable that distinguishes between wrought iron, steel, and cast iron. Too little, and one gets wrought iron; too much and the iron begins to flow as cast iron. Just the right amount of carbon (around 1% or a bit more) and you've got steel. So why didn't everyone make steel? Because the smelting furnace doesn't let the operator control the carbon content with any degree of ...
