Tata Hr Coil

Tata HR Coils, primarily branded as Tata Astrum in India, are Hot Rolled (HR) Steel Coils manufactured by Tata Steel. They are a versatile, high-quality steel product known for strength, durability, and formability, making them suitable for heavy-duty applications.

Product Description and Manufacturing

• Product Type: Hot Rolled (HR) Steel Coil, typically made from Carbon Steel.

• Manufacturing Process: Steel slabs (or transfer bars in some mills) are heated to high temperatures (over 1700F or 927C) and then rolled in a Hot Strip Mill (HSM) to the desired thickness and width. The subsequent controlled cooling ensures the product attains the required mechanical properties.

• Brand Name (India): The hot rolled sheets and coils from Tata Steel are often marketed under the brand name Tata Astrum.

• Dimensions (Typical Range):

  • Thickness: Generally ranges from $1.6\text{ mm}$ to $25\text{ mm}$.

  • Width: Typically ranges from $800\text{ mm}$ to $2050\text{ mm}$ (varying by thickness and plant).

• Coil Finish: Available in:

  • Non-pickled (Dry): The surface retains the mill scale, an iron oxide film formed during the hot rolling process.

  • Pickled and Oiled (HRPO): The mill scale is removed using an acid bath (pickling) for a cleaner, uniform surface, and then oiled to prevent rust.

  • Skin Pass, Pickled & Oiled (HRSPO): An additional process to improve surface smoothness, thickness uniformity, and minor mechanical property corrections.
