Properties of electrolytic manganese

 In the iron and steel industry, electrolytic manganese metal is also used as deoxidizer and desulfurizer. With the gradual progress of metallurgical technology, steelmaking enterprises usually produce manganese steel with high added value. Manganese steel containing 1.4%-1.8% manganese is generally used in the manufacture of connecting rod bolts on automobiles and diesel engines, intake air Gears of valves and machine tools, etc. At present, about 90% of electrolytic manganese is used in the production of steel, especially stainless steel. About 70%-75% of electrolytic manganese is used in the downstream steel industry, 45% is used in manganese steel alloy steel, and 30% is used in 200 series stainless steel. Especially with the development of 200 series stainless steel, the proportion of metal manganese in metallurgy is increasing. 200 series stainless steel is mainly used in the field of consumer goods, all food utensils, cabinet equipment and appliances, and architectural decoration. In steelmaking production, electrolytic manganese is especially suitable for smelting high-manganese steels, heat-resistant steels, precision steels, corrosion-resistant steels and other "special, refined, high" alloy steels containing more than 10% alloying elements and smelting low-impurity, low-alloy steels. Pure steel, pure steel and other steel types without harmful elements. High manganese steel is hard and tough, and has no magnetism and will not be attracted by magnets. For example, alloy steel composed of 84% copper, 12% manganese and 4% nickel has little change in resistance with temperature , are used to manufacture precision electrical instruments. High manganese steel is the main wear-resistant material in mining roads, railway building materials, chemical metallurgy, and abrasive production industries.
