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

These plates and wide flats are rolled on reversing mills. They have nominal thicknesses equal to or less than 150 mm. ISO 7788 specifies requirements, repair procedures, and in annex A definitions of products and discontinuities.
Sep 11, 2014· The differences between hot rolled steel and cold rolled steel relates to the way these metals are processed at the mill, and not the product specification or grade. Hot rolled steel involves rolling the steel at high temperatures, where cold rolled steel is processed further in cold reduction mills where the material is cooled followed by ...
The AR finish (meaning as rolled) is our standard for hot rolled sections in in carbon steel, which is defined by EN 10025. The hot rolling and the final straightening process affect the surface. Admissible imperfections are defined by the EN 10163-3.

The starting material for Cold Rolling always has a No. 1 finish. Cold Rolled material is supplied with the following standard mill finishes. No 2D Finish A no. 1 Finish after being Cold Rolled, Annealed, Pickled and Passivated. This results in a uniform dull matt finish, superior to a No. 1 Finish.
Hot rolling is a metalworking process that occurs above the recrystallization temperature of the material. After the grains deform during processing, they recrystallize, which maintains an equiaxed microstructure and prevents the metal from work hardening. The starting material is usually large pieces of metal, like semi-finished casting products, such as slabs, blooms, and billets.
A bright, cold-rolled finish is the most commonly "Mill" finish for light gauge stainless steel sheet. It resembles a very hazy mirror, with some reflection evident. It is obtained by a final light roll pass of the sheet through polished rolls. This is the general-purpose cold-rolled finish that can be used as is, or a preliminary step to ...
Standard EN 10088 Part 1. Introduction Standard mill finishes and mechanically treated surface finishes of appropriate hot and cold rolled stainless steels are given in EN 10088 Part 2 in which the designations for surface finishes are given by number, for example, 1 for hot rolled, 2 for cold rolled, and classified by a combination of number

Our hot rolled products available in 1/1D surface finish. They are hot rolled, heat treated and pickled. We offer also semi-cold rolled 1/2E surface finish RAP®2E that is a relatively rough shot-blasted finish with cold band tolerances and less roughness than a 1/1D finish…
NOTE: Hot-rolling and cold-rolling should not be mistaken for different grades of steel. Steels of different grades can be produced as hot-rolled or cold-rolled. HOT-ROLLED STEEL. Hot-rolling refers to a mill process in which you roll the steel at a temperature above its recrystallization temperature; a heat that typically exceeds 1000° F.

Cold rolled steel will have a a very uniform finish and uniform dimensions. It looks much more silvery and shiney as opposed to hot rolled steel. hot rolled steel will have a grey/black coating of powdery mill scale that will stain everything it touches. Also the dimensional tolerances will generally be much poorer.
BLACKENED HOT ROLLED. Our Blackened Hot Rolled finish is simple. We use Hot Rolled Steel and clean the original mill scale of the steel to a blue black finish that has a clean, durable, classic industrial look. Actual colors in finish may vary slightly from sample image shown.

Not free of surface imperfections. Hot formed, not heat treated, not descaled. Suitable […]
Deep drawing ability is available by certain alloy and temper combinations. The surface of our sheets may have a mill finish, coated with paper or foil (laser foils are also available), prepainted or embossed. The surface of hot-rolled plates has a mill finish.
The thickness of the hot-rolled strip is important in that the properties of the final cold rolled and annealed product is influenced by the percent of cold reduction. This means that the thickness of each hot-rolled coil is carefully controlled to provide the mill with a specific thickness to achieve the proper percent cold reduction.
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. Hot Rolled vs Cold Rolled Steel Advantages and Use-Cases. Also, the surface has a scaly finish.
Mill Finishes are the least expensive finish option. There are both hot-and cold-rolled mill finishes, and, as this description implies, their appearance is produced at least in part by passing the stainless steel through special rolls or dies. The reflectivity of these finishes varies from dull to mirror-like.
Also, the surface has a scaly finish. This is a kind of oxide that forms at high temperatures, known as mill scale. It is easy to identify hot rolled products by touching the surface because of the uneven finish but it is also lacking an oily film. With steel bars, the corners are rounded. Hot Rolled Steel Uses
Hot rolled surface finishes The use of stainless steel is increasing fast due to the material's durability and corrosionresistance. If the right grades and surface finishes are selected, stainlesssteel lasts hundreds of years making it the least expensive material, thanks to its lowmaintenance costs.
Cold Rolled Steel Smooth finish Higher carbon content than hot rolled steel Tighter tolerance control Can be used raw and will develop an oxidized (rusty) look. Will need coating with paint, clear, or other protective layer if oxidation is not desired Hot Rolled Steel Panel 9
