T11 steel has good hardness, wear resistance and toughness, such as mechanical properties (such as strength, hardness, wear resistance and toughness, etc.). The carbon content is between T10, T12 between. For production of tap, file, reamer reaming, die, scrapers, gauges, carpentry tools. You can also make cold heading die, Die small size, trimming molds. The carbon content is between T10, T12, between has good mechanical properties (such as strength, hardness, wear resistance and toughness, etc.). T10 steel with the same purpose, but not as good as T10 steel extensively.
