thumb|A World War I Brodie helmet|M1917, made from [[Hadfield steel]] Mangalloy, also called manganese steel or Hadfield steel, is an alloy steel containing an average of around 13% manganese. Mangalloy is known for its high impact strength and resistance to abrasion once in its work-hardened state.
==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. This allows mangalloy to retain its toughness.
