2. The processed iron ore boasts high yield, good quality, and low production costs.

3. Steel's physical properties are relatively stable. It can be categorized into construction steel, as well as profiles, plates, and so on. The quality and chemical composition also vary significantly, making it applicable to various economic sectors.

4. Additional rare metals are added to the iron, which enables different functionalities, and this technology cannot be replaced by other materials, such as carbon steel or alloy steel.

5. Steel is also a recyclable product.

6. Steel boasts excellent weldability and is one of the higher grades among various metal materials, with a notably high strength as well.

7. This material boasts good strength, and its flexibility and tensile strength are well-balanced. Compared to cast iron, its edges are sharper. Importantly, its brittleness is higher than cast iron, and it also offers better impact resistance and tensile properties.
