Manganese metal lump mn metal 95 pct
Manganese is a silver-gray metal, much like iron, but softer than iron. If manganese contains a small amount of impurities-carbon or silicon, it becomes very hard and brittle. However, pure metallic manganese is not very widely used because it is more rusty than iron. In humid air, it becomes gray and loses its luster in a short while-a layer of manganese oxide is formed on the surface.
Application:
1. In the iron and steel industry, metal manganese is mainly used for desulfurization and deoxidation of steel.
2. Manganese can be used as an alloy additive to improve the strength, hardness, elastic limit, wear resistance and corrosion resistance of steel.
3. In high-alloy steel, metallic manganese is also used as austenite compound element for making stainless steel, special alloy steel, stainless steel electrode, etc.
