Recently, Ansteel succeeded in developing 200 tons of T10A hypereutectoid hot-rolled coil with carbon composition up to 1%. Ansteel claimed that they are China's first mill in this field to fill the domestic blank. Thanks to its high wear resistance with higher added value, T10A hypereutectoid hot-rolled coil, as a kind of tool steel, is often used as raw material for tool knives like steel tape and surgical blade. Due to the high carbon content of the steel, smelting and rolling is so difficult that there is no precedent for domestic production and supply. The first lot of 200 tons has met the user’s requirements for chemical composition, inclusion, decarburization layer, microstructure and properties, surface quality and other technical indicators.
