Hot Rolled and Pickled Steel Coils

Hot Rolled Coils

Hot Rolled Sheet is the most basic and, typically, least expensive type of flat-rolled steel. It is used in its original form or becomes the feedstock for Cold Rolled and coated sheet steels. Usually produced in conformance with ASTM A568.

Categories

Unprocessed (a.k.a. "Band"): The crudest flat-rolled form. Coil product not cut back to gauge at ID and OD, not edge trimmed, not temper-rolled. Surface subject to mill finish, crossbreaks, scale and rust. Some mills are installing scale breakdown rolls to improve surface and eliminate the need for subsequent pickling. Unprocessed is usually not intended for applications requiring critical surface, flatness or tight thickness tolerances.

Temper Rolled (a.k.a. "Sheet"): An upgrade from Unprocessed, the coil is temper-rolled (a.k.a. skin passed), edge-trimmed, with coil ID and OD cropped back to ordered thickness. Provides improved flatness, smoother surface, and absence of L├╝ders Lines.

Pickled: A product that has been washed in hydrochloric and/or sulfuric acid to remove scale and rust. Has a smoother surface than unpickled unprocessed coil or sheet. After pickling, should promptly be oiled to protect against rust. Can be applied to Unprocessed or Temper Rolled product. Usually intended for applications requiring clean surface (i.e., for improved painting or die forming).
