Manganese metal is a desulfurizer and deoxidizer, especially of liquid steel. It causes a grinding effect on the steel structure, increasing the depth of calcination. With a content of up to 7% manganese, the tensile strength of steel increases significantly. Corrosion resistance increases significantly with more than 10% manganese content.
Pieces of metal manganese, both in the fracture and on the surface, should not be contaminated with sand,
slag and other foreign materials. Traces of non-stick materials and oxide film in manganese are allowed
brand Mn95.
Manganese is a toxic substance, long-term exposure to which causes in the central nervous system
organic changes. Inhalation of dust from manganese-containing materials, in addition to general toxic effects, can cause
contribute to the development of a special form of pneumoconiosis - manganoconiosis.
