Chemical Composition Of High Manganese Steel
May 09, 2023
High manganese steel is divided into 5 grades according to national standards, the main difference is the carbon content, which ranges from 0.75% to 1.45%. High impact and low carbon content. The manganese content is between 11.0%-14.0%, generally not less than 13%. There is no national standard for ultra-high manganese steel, but the manganese content should be greater than 18%. The level of silicon content has a great influence on the impact toughness, so the lower limit should be taken, preferably no more than 0.5%. Low phosphorus and low sulfur are the most basic requirements. Since the high manganese content naturally plays a role in desulfurization, phosphorus reduction is the most important thing. Try to keep phosphorus below 0.07%. Chromium improves wear resistance, generally around 2.0%.
