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. This allows mangalloy to retain its toughness.

2020.10.16 Hadfield steel also known as Hadfield steel or Hadfield austenitic manganese steel was invented by Sir Robert Hadfield in 1882. The first British patent for this steel, number 200 was granted for this steel in 1883. The first US patents, numbers 303150 and 303151, were granted in 1884.
Read MoreManganese Steel. The austenitic manganese steel appears to form a reaction product at the metal-mould interface giving very poor surfaces. They often appear as irregular very rough surfaces and in many cases skins are adherent to the casting giving the appearance of thin scabs. It is difficult to grind manganese steel, and very bad surfaces may ...

Feature. High manganese steel refers to high alloy steels containing more than 10% manganese. The biggest features of high-manganese steel are: The greater external compressive stress or impact load, the more conducive to the formation of hardened layer, so the higher the wear resistance of the casting;

2008.8.1 Hadfield austenitic manganese steel in the as-cast condition contains (Fe, Mn) 3 C carbides. It is a common industrial practice to solutionize the material before use so that (Fe, Mn) 3 C goes into solution giving completely austenitic structure. Generally, it is solution-annealed at 1,050 °C for few hours followed by water quenching.
