Recently, Anshan Iron and Steel Company of Ansteel Group successfully developed the T10A hypereutectoid hot-rolled coil with carbon content as high as 1% and became the first enterprise in China to successfully develop the hot-rolled coil with the steel grade, filling in the domestic blank.
T10A Hypereutectoid hot-rolled coil steel is a kind of tool steel, because of its high wear resistance, is often used as a tape measure and scalpel and other tool knife raw materials, high added value due to the steel carbon content than High, smelting and rolling difficult, there is no domestic production and supply precedent.
By the end of 2016, Ansteel Group Steel Research Institute set up a research group to develop such a steel plate.After sufficient preliminary studies in the laboratory, access to accurate reference to the thermoplastic, thermal strength curve, strength level, etc. R & D, metallurgy, rolling related According to the characteristics of the steel, the technicians have carefully designed the smelting, heating, rolling and cooling process routes and process parameters. With the close cooperation between the steel making department and the hot rolling department of the Baotu ring branch of Angang Holding, In the near future, it has successfully produced over 200 tons of T10A hypereutectoid hot-rolled coil. The chemical composition, inclusion level, decarburized layer, microstructure and surface quality meet the customer's requirements.
