High manganese steel, also known as "hadfield steel," was created in 1882 by the British R.A. Hadfied. This form of steel typically has a high carbon content of 0.90% to 1.50% and contains 10% to 15% manganese . This material has a high surface hardening ability, while the core retains its original high plasticity and toughness.
