Hot Rolled Steel
Manufacturing High-Quality Hot Rolled Steel Sheets with Latest Technology Hot rolled steel refers to steel sheets that have been thinned up to 6 mm by heating, pressing, and extending semi-finished steel slabs made by processing molten metal from blast furnaces. HYUNDAI STEEL possesses a production capacity of 8.5 million tons a year to manufacture high quality hot rolled steel plates through its integrated production system with latest equipment. Hot rolled products are widely used in different industries including automotive, structures and steel pipes for construction.

Product Classification/Uses

  • Automobile
    Steel sheets that are used for automotive bodies are high in strength and resistant to fatigue, which can increase overall safety and lifespan of cars. The product is highly processable that it can be easily shaped to a car design which is increasingly diversified and also has the properties appropriate for lightweight automotive bodies. It is mostly used for car frames, wheels and exteriors.

  • High Pressure Gas Cylinder
    The product has enabled excellent processability and minimized mechanical property deviation by length by managing the temperature by each process in hot rolling. It especially maintains outstanding cleanliness through impurity management as this is directly connected to safety. It is mostly used for pressure vessels or gas tanks.

    - Major Products
  • High Carbon / Low Alloy Steel
    The product possesses high strength, high hardness, and wear resistance by adding mass quantity of carbon and alloy elements, as it requires tolerance on repeated operation and friction. It is mostly used for special purposes such as automotive parts, chains, knife blades, and tools.
