Manganese Metal (Mn)-Pellets
Product Description
Characteristic
Manganese is a chemical element with the atomic number 25, VIIB.Is a kind of gray, hard and brittle, shiny transition metal, pure metal manganese is slightly softer than iron metal, containing a small amount of impurities manganese hard and brittle, moist place will oxidation.In the solid state it exists in four allotropes: alpha manganese, beta manganese, gamma manganese, delta manganese.The ionization energy is 7.435 electron volts.A variety of industrial alloys are used,particularly in stainless steels.

Application
It is mainly used for desulfurization and deoxidation of steel in iron and steel industry.It is also used as alloy additive to improve the strength, hardness, elastic limit, abrasion resistance and corrosion resistance of steel.In high alloy steel, also used as austenitic compound elements, used for refining stainless steel, special alloy steel, stainless steel welding rod.In addition, it is also used in nonferrous metals, chemical industry, medicine, food, analysis and scientific research.
