In manganese: Occurrence, uses, and properties. Manganese steel is used for very rugged service; containing 11–14 percent manganese, it provides a hard, wear-resistant, and self-renewing surface over a tough unbreakable core. Pure manganese produced electrolytically is used mostly in the preparation of nonferrous alloys of copper, aluminum, magnesium, and nickel and
Material properties. Mangalloy is made by alloying steel, containing 0.8 to 1.25% carbon, with 11 to 15% manganese. Mangalloy is a unique non-magnetic steel with extreme anti-wear properties. The material is very resistant to abrasion and will achieve up to three times its surface hardness during conditions of impact, without any increase in brittleness which is usually associated with hardness.

It was discovered 1774 by Johann Gahn. Manganese easily reacts with water and air. On Earth, manganese is never found as a free metal, but it is found in a number of minerals. The most important of these minerals is pyrolusite, the main ore mineral for manganese. Manganese is essential to iron and steel production.
Manganese steel has no equal in it ability to work-harden. Although it is normally reported that a maximum hardness of about 550 BHN is obtainable, typical maximum hardness on worn castings is in the 400–450 BHN range. It is generally believed that manganese steel has poor abrasion resistance unless it has been work-hardened.
Manganese Steel in service. In 1907 the steel used on the tramway junction at Fitzalan Square in Sheffield, UK was replaced and reconstructed using manganese steel. The manganese steel lasted for 12 years with an estimated 13.5 million tramcars having passed over it. The previous layout, constructed of carbon steel, had worn out in just 3 months.
A manganese steel foundry may have several dozen modified grades on its production list. Modified grades are usually produced to meet the requirements of application, section size, casting size, cost, and weldability considerations. The mechanical properties of austenitic manganese steel vary with both carbon and manganese content.
For automotive steel sheets, a specialized high-Mn steel with a moderate amount of Al and Si has been developed, in which the stacking fault energy is controlled so as to form deformation twinning during cold working (e.g., Fe–(15–30)%Mn–Al–Si–C alloy). This new class of high-Mn steel is called twinning-induced plasticity (TWIP) steel.
Manganese steel (Manganal) is an austenitic steel which means it is non-magnetic. This property makes it useful in many applications such as bottom plates for lifting magnets – separator drum shells for magnetic materials – wear shoes on electric brakes etc.
Austenitic manganese steel is used in equipment for handling and processing earthen materials, such as rock crushers, grinding mills, dredge buckets, power shovel buckets and teeth, and pumps for handling gravel and rocks. The mechanical properties of austenitic manganese steel vary with both carbon and manganese content. Austenitic manganese ...
Manganese is essential to iron and steel production by virtue of its sulfur-fixing, deoxidizing, and alloying properties, as first recognized by the British metallurgist Robert Forester Mushet (1811–1891) who, in 1856, introduced the element, in the form of Spiegeleisen, into steel for the specific purpose of removing excess dissolved oxygen ...

Manganese (Mn) is a hard, gray metal that is frequently used in the production of steel. Workers may be harmed from exposure to manganese through the breathing of manganese fumes or dusts. Continued exposure can damage the lungs, liver, and kidneys. Exposure to manganese dust or fumes can also lead to a neurological condition called manganism.

Exposure to manganese dust occurs primarily in mining, ore-crushing, and metallurgical operations for iron, steel, ferrous and nonferrous alloys. Manufacturing of dry-cell batteries, anti-knock gasoline additives, pesticides (e.g. maneb), pigments, dyes, inks and incendiary devices can also lead to occupational manganese exposure.
Manganese is about half as effective in forming austenite as is nickel, so for every 1% reduction in nickel content, roughly 2% of manganese must be substituted. Because the broadly named 18-8 stainless (301, 304 types) constituted the largest consumption of stainless, it was the first to be targeted for nickel substitution and the result was ...

Source: USGS Prospects For Manganese. Manganese's use in steel production is a double-edged sword, as the metals' fortunes are intimately tied to those of the steel industry.
Manganese (Mn) is essential to iron and steel production by virtue of its sulfur-fixing, deoxidizing, and alloying properties. Steelmaking, including its ironmaking component, accounts for most domestic manganese demand, presently in the range of 85% to 90% of the total. Manganese ferroalloys, consisting of various grades of ferromanganese and silicomanganese, are used to
ASTM A225 steel is an alloy steel formulated for primary forming into wrought products. It has a fairly high thermal conductivity among wrought alloy steels in the same category. In addition, it has a fairly low base cost and can have a moderately high embodied energy. The properties of ASTM A225 steel include two common variations.
