<p>A manganese steel and production method thereof, said manganese steel comprising the following components by mass percentage: carbon 0.2-1.0%, manganese 5-15%, aluminum 0.02-1.0%, phosphorus <0.025%, sulfur < 0.025%, nitrogen < 0.03%, silicon 0.03-2%; and further comprising at least one of the following alloying elements: titanium 0.01-1.2%, niobium 0.01-1.2%, vanadium 0.01-1.2%; the remainder being elemental iron. Using the described scheme provides a steel having both TWIP and TRIP effects; in contrast to existing TWIP steels, the steel of the invention has a lower manganese content, has the advantages of high strength, high plasticity, and low cost, and has value in market applications.</p> |
