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, .
Feb 21, 2020· As flat product, mirror finishes are produced by post mill abrasive polishing of either hot rolled or cold rolled sheet or strip. Although mirror finishes are only defined in standards for flat products, it is also possible to generate a mirror polish on surfaces where there is sufficient access for the grinders and polishing mops.
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.

Whether we are talking hot rolled or cold rolled, all stainless steel flat products are treated with a standard mill finish. Let's review two of the more common mill finishes: • 2B : This is achieved by cold rolling, heat treating and pickling, along with the application of a light rolling at the end in order to achieve a .
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.

Suitable for forming applications. 2B: No. 2B: 2B: Cold rolled, heat treated and pickled. Bright and smoother finish than 2D (obtained by skin passing or tension ...
Hot rolled parts are usually dark and dull, their surface oxidized from being hot worked. Extruded products may have die marks running the length of the stock. Other mill finishes are surprisingly smooth and uniform. It is possible for a mill to influence the finish of produced stock.
Hot rolled steel has been roll-pressed at high temperatures (over 1,700Ë F), which is above the re-crystallization temperature for most steels. This makes the steel easier to form, and also ...
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
Surface finish of hot rolled steel plates Steel plates must have a workmanlike finish and must be free from defects and imperfections which may impair their proper workability and use. This may, however, include some minor imperfections, e.g. pittings, rolled-scale, indentations, roll marks, scratches and grooves which cannot be avoided despite ...
Cold Rolled Steels can be joined using accepted welding practices. SURFACE FINISH Cold Rolled Steels are manufactured with a matte finish obtained by rolling with specially roughened rolls on the cold mill and the temper mill. This finish helps to maintain effective lubrication during metal forming and improves the appearance of painted surfaces.

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.
