Mangalloy was created by Robert Hadfield in 1882, becoming the first alloy steel to both become a commercial success and to exhibit behavior radically differing from carbon, it is generally considered to mark the birth of alloy steels. Benjamin Huntsman was one of the first to begin adding other metals to steel. His process of making crucible steel, invented in 1740, was the first ...

Manganese bronzes are a group of high strength copperbased alloys that include manganese as an alloying agent and high levels of zinc. They are characterized by high strength and hardness. This grade provides tensile strength to 110,000 psi and hardness well over 200 BHN.
This is basically natural Manganese Dioxide, which is having low chemical reactivity and poor application results, besides being loaded heavy metals and other impurities. To overcome these problems occurring in natural Manganese Dioxide, synthetic Manganese is produced by chemical process.

High Carbon Steel: Composition of %% carbon, with %% manganese. It is very strong and holds shape memory well, making it ideal for springs and wire. Very High Carbon Steel: Composition of %% carbon. Its high carbon content makes it an extremely strong material. Due to its brittleness, this grade requires special handling.
Manganese bronze alloys can operate under very high loads and speeds. However, bearing applications require reliable lubrication. Besides excellent mechanical qualities, these alloys have good corrosion resistance. The standard alloy in this group is high tensile C86300, which is comprised of copper, manganese, aluminum and iron. This ...
The main product of the smelting process is a carbonsaturated ferroalloy consisting of 76 to 80% manganese, 12 to 15% of iron, % of carbon, and % of silicon. 70 to 80% of the manganese is recovered in the melt, and a slag consisting of 30 to 42% manganese is also achieved.

Apr 03, 2014· Fig 1 Typical microstructure of austenitic manganese steel. The basic condition for the chemical composition of AMS is the ratio Mn/C=>10. The upper borderline is normally 15 % Mn but in practice this ratio can be increased to 20 % mostly in thick walled castings. The main reason for using of high content of Mn is to improve the hardenability.
manganese is permitted, up to a maximum of % for Grades 50, 60, 70 and up to a maximum of % for Grade 80. B The contents of columbium and vanadium shall additionally be in accordance with one of the following: Columbium % with vanadium <%; Columbium <% with vanadium %; or
