during the production process to produce an increased hardness in the rail head. Austenitic Manganese Steel (AMS) Austenitic Manganese steel is only slightly magnetic, hence the use of a magnet as a simple method of determining this type of steel. All other current grades of rail are strongly attracted to a magnet.
The ignition temperature for thermit mixture containing iron oxide is about 1200°C. Though the metal oxide used in Thermit welding is usually iron oxide however oxides of copper, nickel, chromium, and manganese can also be employed to give the following reactions and the corresponding theoretical temperatures attained.
The thermit process generates by aluminothermic reactions heat for thermit welding and similar processes. One of the first imp artial scientific publications about this process and its practical applications in the U.S.A. was published by Richard N. Hart in 1910 in his book on Welding Theory, Practice, Apparatus and Tests, as shown below:
Ferromanganese is a ferroalloy with high manganese content (high-carbon ferromanganese can contain as much as 80% Mn by weight). It is made by heating a mixture of the oxides MnO 2 and Fe 2 O 3, with carbon (usually as coal and coke) in either a blast furnace or an electric arc furnace-type system, called a submerged arc furnace.The oxides undergo carbothermal reduction in the furnaces ...

· Ferro-manganese (Fe-Mn) is an important additive used as a deoxidizer in the production of steel. It is a master alloy of iron (Fe) and manganese (Mn) with a minimum Mn content of 65 %, and maximum Mn content of 95 %. It is produced by heating a mixture of the oxides of Mn (MnO2) and iron (Fe2O3) with carbon (C) normally as coke or coal.

Red iron(III) oxide (Fe 2 O 3, commonly known as rust) is the most common iron oxide used in thermite. Magnetite also works. Other oxides are occasionally used, such as MnO 2 in manganese thermite, Cr 2 O 3 in chromium thermite, quartz in silicon thermite, or copper(II) oxide in copper thermite, but only for specialized purposes. All of these examples use aluminium as the reactive metal.
