a metal that occurs naturally in rock. It is used in the manufacture of steel.

A naturally occurring metal that can be found throughout the world in soil, water, and many types of food such as grains and cereals. Manganese is also found in pesticides and is used as a fuel additive in some gasolines. Another common use of manganese is in a steel alloy compound that produces stronger steel resistant to wear. Although necessary in the human diet in trace amounts, excessive quantities may lead to manganese poisoning. Learn more about manganese.

These substances naturally occur at low levels in the water and may be responsible for taste and staining problems with water. They are measured in milligrams per litre (mg/L).

Lustrous redish-white metal of hard brittle and therefore non malleable character. Element number 25 of the periodic system. Atomic weight 54.93.

A metal resembling iron and having a strong affinity for it. Used in the manufacture of all steels, the percentage thereof generally varying between one-half and unity.

a metal element found in AMD that oxidizes as a blackish stain.

Manganese is important because it deoxidizes the melt and facilitates hot working of the steel by reducing the susceptibility to hot shortness. It combines with sulfur to form MnS stringers which increases machinability. Manganese contributes to the effectiveness of normalizing for strengthening, to the formation of fine pearlite, and lowers the Ms temperature, therefore increasing the probability of retained austenite.

A metallic element added to steel to increase hardenability, and to combine with excess sulfur to form manganese sulfides which remain solid at elevated temperatures thereby improving the hot workability of steels.

An element sometimes found dissolved in ground water, usually with - but in lower concentrations than - iron. Manganese causes black stains and other problems similar to iron. It can be removed by a water softener.

The presence of manganese in amounts greater than 0.05 mg/l may give water a bitter taste and produce black stains on laundry, cooking utensils, and plumbing fixtures. It generally does not present a health risk.

(Mn) An element on the Periodic Table. Symbol Mn. Sometimes found in ground or surface water usually in combination with iron. Manganese is noticeable because it causes black staining when concentration is greater than 0.05 ppm.

Manganese is a naturally occurring metal that is found in many types of rocks. In addition to natural sources, human-made sources of manganese include the burning of fossil fuels, emissions from the steel industry, and the use of synthetic manganese compounds in pesticides. Although manganese is an essential element necessary for good health, at elevated levels it can become a neurotoxin.

A gray-white or silvery brittle, metallic, element which resembles iron but is not magnetic. It is found abundantly in the ores pyrolusite, manganite, and rhodochrosite and in nodules on the ocean floor. Manganese is alloyed with iron to form ferromanganese, which is used to increase strength, hardness, and wear resistance of steel.

One of the most important constituents of steel in which it fulfils a number of functions. It acts as a mild de-oxidizing agent. It combines with the sulphur present to form globular inclusions of Manganese Sulphide which are beneficial to machining. It increases tensile strength and the hardenability of steel. Will also increase hardness as levels increase, but not to the same degree as carbon. Ductility and weldability are decreased but, again, to a lesser degree than caused by carbon.

The element MANGANESE is a metal that sits adjacent to the iron element in the Periodic Table of the Elements. Unlike Iron, MANGANESE does not oxidize very easily and is non-magnetic. Found in places like nodules on the ocean floor and within mangrove trees, MANGANESE is said to be able to improve memory in body cells if absorbed properly. Having the same atomic diameter as the iron element, MANGANESE can replace iron in the body - however, "rusted" iron is essential in carrying oxygen throughout the body.

(Chemical symbol Mn.) Element No. 25 of the periodic system; atomic weight 54.93. Lustrous, reddish-white metal of hard brittle and, therfore, non-malleable character. The metal is used in large quantities in the form of Spiegel and Ferromanganese for steel manufacture as well as in manganese and many copper-base alloys. Its principal function is as an alloy in steel making: (1) It is ferrite-strengthening and carbide forming element. It increases hardenability inexpensively, with a tendency toward embrittlement when too high carbon and too high manganese accompany each other. (2) It counteracts brittleness from sulfur.

Grayish white metallic chemical element often used as a coloring agent. Atomic Number 25. Atomic Symbol Mn. Atomic Weight 54.938.

A most useful additive to steels. Mild deoxidiser. Combines with sulphur and so decreases the chance of the steel suffering from hot shortness. Improves the toughness of ferrite-pearlite steels. Improves hardenability. Hadfield's manganese steel, which is characterised by its great resistance to wear, contains around 13% Mn. It is used in some grades of austenitic stainless steel to replace the more expensive nickel as it is an austenite stabiliser.
