This invention relates to manganese steels, in particular the invention relates to high strength iron-manganese based maraging-type steel combining high strength and toughness. Specifically, a manganese steel in accordance with the invention contains, apart from impurities, 11.8-13.5% by weight manganese, 2.0-6.0% by weight molybdenum, 0.002-0.2% by weight carbon, and optionally one or more of silicon (up to 0.4% by weight), sulphur (up to 0.02% by weight), and phosphorus (up to 0.03% by weight), and balance iron.
