Develop a type of rare earth corrosion-resistant carbon steel with Chinese characteristics. Corrosion is one of the main failure modes of steel materials. It is necessary to solve the corrosion problem of large-scale and widespread carbon steel (accounting for about 70% of the total output) in a low-cost and green manner. Rare earth corrosion-resistant carbon steel effectively utilizes China's abundant lanthanum and cerium rare earth resources, endowing carbon steel with atmospheric corrosion resistance (increasing by 30%-50%). The cost of rare earth alloy per ton of steel is less than 10% of that of traditional weather-resistant steel alloys. It is a new type of green and low-cost steel. The series of rare earth corrosion-resistant carbon steel products include hot-rolled strip coils, hot-rolled plates, rebar, wire rods and sections, with strength levels ranging from 195 to 550 MPa. It is applied in fields such as steel structures, highway guardrails, communication tower, photovoltaic supports, protective wire meshes, urban decoration, containers, and building rebar.
