Finish: Description: 2B: The general-purpose, cold rolled, smooth finish obtained as a result of a final light pass through polished rolls at the mill. BA: Bright annealed finish is a bright, cold rolled, highly reflective finish retained by final annealing in a controlled atmosphere furnace.
Hot Rolled Steel. This is the most common and simple finish and the first step to making steel plates and sheets. A steel slab is heated, typically to 1,700 degrees F, and passed through a series of rollers - each set of rollers making the slab thinner until the desired thickness is achieved.
suppied in various finishes, including the hot-rolled, pre-machined and fine machined condition. It is also available in the form of hollow bar and rings. HEAT TREATMENT SOFT ANNEALING— Protect the steel and heat through to 1560°F (850°C). Then cool in the furnace at 20°F (10°C) per hour to 1200°F (650°C), then freely in air. STRESS ...

rolled through all six stands at once. The hot steel is quite fragile as it is rolled and tension between the finishing mill stands must be closely controlled at very low levels in order to avoid stretching or tearing the strip. Prior to the finish rolling operation, the head- and tail-ends of the transfer bar will be sheared to square them up,
All coldproducts provide a superior surface finish, and are superior in tolerance,concentricity, and straightness when compared to hot rolled. Cold finishedbars are typically harder to work with than hot rolled due to the increasedcarbon content. However, this cannot be said about cold rolled sheet and hotrolled sheet.
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
Tata Steel's hot-rolled high-strength, low-alloy (HSLA) grades offer formability and strength for demanding applications. The range includes Ympress ® with grades that exceed the Euronorm, resulting in stronger and lighter products with increased yield and simplified processing. Our Ympress ® Laser range was developed specifically for fast and efficient laser-cutting.
Keep a low cut width (or cut depth if you're talking the floor of a pocket or surfacing with a Face Mill) and do a separate finish pass. The depth of cut has to be larger than the chip load, or you can get rubbing. Usually something like 2-3x chip load will be right for the finish pass.

I've face milled 4140 at over 1400 SFM. and got good tool life, and it was nice and shiny.. DOC. For some reason, on a gummy steel, you NEED a decent DOC to get a good surface finish. .001 is not going to do it, on almost any material.. .010 to .030" at least.. Feed, you *NEED* a proper feed rate.. moving the table very slow.
Mill finish is the surface texture (or finish) of metal after it exits a rolling mill, extrusion die, or drawing processes, including sheet, bar, plate, or structural shapes.This texture is usually rough and lacks lustre; it may have spots of oxidation or contamination with mill oil. Most mill finish surfaces are machined or treated with polishing, industrial etching, or some other surface ...
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. Here is an in-depth description of the stainless steels that fall into this group according to the table above.

Hot rolled steel is mill process by which the steel is roll pressed at a high temperature. Generally, the temperature for hot rolled steel exceeds 1700°F. Cold rolled steel is a process by which steel is roll pressed at room temperature. It is important to note that both hot rolled steel and cold rolled steel are not steel grades.
However, Myanmar's producers are unable to meet domestic demand, so the country's steel products are more dependent on imports. In 2019, Myanmar imported more than 1.9 million tons of QStE380TM hot rolled steel coil finished steel, including 57% of long products, 13% of uncoated hot-rolled and cold-rolled flat products, and 30% of coated steel.

Surface Finish. Probably the easiest of the features to see and verify is the third on our list, surface finish. One can easily recognize the difference in finish when comparing a cold finished bar to a hot rolled bar. A hot rolled bar comes out of the mill with a rough, abrasive, discolored, and dirty surface.
12-21-2009, 05:05 PM. 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.

the hot rolled pickled and oil product through a series of progressive dies or rollers at room temperature. The effect of such work stretches the steel, which creates a permanent increase in the hardness, strength, and finish of the product.
