Manganese is a pinkinsh-gray, chemically active element. It is a hard metal and is very brittle. It is hard to melt, but easily oxidized. Manganese is reactive when pure, and as a powder it will burn in oxygen, it reacts with water (it rusts like iron) and dissolves in dilute acids. Applications. Manganese is essential to iron and steel production.

Apr 30, 2020· The ore is particularly useful in increasing steel's resistance to oxidation, so manganese is often used to make stainless steel. The addition of manganese to steel can also improve the overall strength and workability of the material. Hadfield Steel is one example of a mixture of steel and manganese, and is known for both these properties.
