Rolled steel can be categorized into two types—hot rolled steel and cold rolled steel—which demonstrate distinct characteristics that make them suitable for different applications. When choosing a rolled steel material for a project, it is important to be aware of the differences between the two types and how they affect their performance.
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,
Most steel fabricators are using A36 Hot Rolled "Mild" steel for bars, shapes and tubes and some sheets. All of this material comes from the mill covered in an extremely hard blue grey oxide layer called Mill Scale. 1018 is the alloy of choice for Cold Rolled Steel for sheets, which it is more costly than A36, and it arrives scale free.
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
Our rolled out coils are extremely potent to counter pitting corrosion. These coils due to the presence of aluminum have a smooth outer finish. This kind of finish makes Aluminum Alloy 5005 Coil look appealing. It is known for demonstrating a lower rate of scaling in normal atmospheric conditions.
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. Cold finished steel is typically ready to be used for manufacturing finished goods, but in some

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.

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.
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 …

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.
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.

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.

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.
