Manganese: Nodules, Uses, Facts, Ore, Alloys, Metal

As an alloy, it decreases the brittleness of steel and imparts strength. The amount of manganese used per ton of steel is rather small, ranging from 6 to 9 kilograms. About 30 percent of that is used during refinement of iron ore, and the remaining 70 percent is used as an alloy in the final steel product. Manganese Can Color Glass: Ancient Egyptians …
