As for the lamination processes, the standard steel mill finishes and the mechanical surface finishes of stainless steel in bars and slabs, both hot and cold rolled, are included in the EN 1008 part 2 standard and indicated with specific numbers: Keyline: 1 = Hot Rolled (abbreviation 1 = HRC = hot rolled) 2 = Cold Rolled (2 = CRC = cold rolled)

Ex-mill hot rolled finishes. The table shows the BS EN 10088-2 hot rolled finishes from table 6 of the standard, with a guide to typical Ra values (in micro-metres), based, where available, on manufacturers or surface finishing contractors' data.

A mill finished steel bucket. A mill finish is typically the finish a material has as it exits the mill where it is processed. Most metals, such as aluminum, are polished after they leave the mill. This leaves the materials bright and shiny and removes any residue that might be present. A mill finish, however, will often be dull, grainy and ...

John G. Lenard, in Primer on Flat Rolling (Second Edition), 2014 1.2.5 Cooling. After exiting the finishing mill, the strip, at a temperature of 800–900°C, is cooled further under controlled conditions by a water curtain on the run-out table.The run-out table may be as long as 150–200 m. Cooling water is sprayed on the top of the steel at a flow rate of 20,000–50,000 gpm; and …

The European norm EN 10088 defines various standard mill surface finishes having as main distinction the productio process, either hot or cold produced. All stainless steel profiles supplied by Montanstahl can be classified according to these tables. Depending on the manufacturing technology, we do offer the following standard finishes for our ...

Dull Buffed – EN No. 2J for Cold Rolled A semi-dull finish with a uniform grain generally applied to the supplied surface of the mill finish stainless steel. No pre-grinding is involved, so only the smoother mill finishes such as 2A or 2B can be used. This finish is obtained using a bristle type brush or fine abrasives. It is used

Mill Finishes for Stainless Steel. Mill finish is the basic supply condition for stainless steels, no matter whether they are cold or hot rolled. However, most of these steels require further finishing processes to meet the requirements of certain applications.

Mill Finishes: Hot Rolled, Softened & Descaled (HRS & D) Hot Rolled, Annealed and Pickled (HRA&P). No.1 (1D) Dull finish characteristic of steel after hot rolling, annealing and pickling.
