Hot Rolled Steel. Hot rolling is a mill process which involves rolling the steel at a high temperature (typically at a temperature over 1700° F), which is above the steel's recrystallization temperature. When steel is above the recrystallization temperature, it can be shaped and formed easily, and the steel can be made in much larger sizes. ...
Easy-To-Form Multipurpose 1050 Spring Steel Sheets Containing more carbon than low-carbon steel— but less than 1095 spring steel— 1050 spring steel is easily formed into parts such as washers, brackets, and springs before being hardened for use.
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.

A very stiff, cold-rolled strip intended for flat blanking only, and not requiring ability to withstand cold forming. No. 2. (half-hard) 65 000 ± 10 000. [ 450 ± 70 ] 10 ± 6. A moderately stiff cold-rolled strip intended for limited bending. No. 3.
Structural shapes like I-beams are usually hot rolled. The formula of steel used for I beams is different than used in cold forming. It's less ductile and harder, which makes it tougher to bend cold, hence the use for structural shapes that carry a lot of weight! Cold roll forming has many commercial and industrial uses.
Cold rolled steel, (often referred to as Cold reduced or CR), is a low carbon product, produced using raw material such as coke and coal at steel mills through out the world. Cold Rolled Process Before becoming a cold rolled product, it is effectively hot rolled steel, which then under goes further processes.

This post will explain the four different steel forming process: hot rolled steel, cold rolled steel, forged steel and cast steel. Definition & differences.
There are two major kinds of mild steel, cold rolled and hot rolled steel. Hot rolled steel is shaped and rolled at high temperatures. Hot rolled steel has a black oxide coating called mill scale. To patina hot rolled, the mill scale must come off.
* All 'value length' and 'value pack' item measurements are subject to a "mill tolerance". A product may be produced several thouhs of an inch, either over or under the stated thickness, and still be within "mill tolerance". This does NOT apply to Cut To Size items. Those will be +.125", -0.00" tolerances.
Hot rolled steel involves rolling the steel sheets above re-crystallization temperatures. Whereas cold rolled steel is processed at room temperature in cold reduction mills followed by annealing and tempering. Click this link!! to know various materials used to manufacture sheet metal parts. Each of these steels has its advantages, limitations ...
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. When steel is heated past its recrystallization point, it becomes more malleable and can be properly formed and shaped. It also allows for the ability to produce ...
Typically, mills take hot rolled steel after it's mostly or completely cooled and work it to its final dimension by either rolling it, extruding it, or drawing the metal over a mandrel. For this reason, it's usually referred to as "cold finished" in the industry instead of "cold rolled".
Cold Roll Steel. Rectangle Bar. 1018. Cold Finish. Over 6. +/- 0.013". Width governs the tolerances both width and thickness for rectangle bars. If the bar is 1.5" thick x 3.5" wide, the width tolerance of +/-0.006" will be the tolerance for the thickness as well, which is +/-0.006". Metric Rectangle Bars.
Hot Rolled Pickled & Oiled. Conventional pickled and oiled hot rolled steel is steel that has been cleaned using hydrochloric acid to remove mill scale. A recent development is eco pickling, which is an environmentally safer method that achieves the same results via a high-pressure slurry blasting system that removes mill scale.
Hot Rolled Profiles – When Stainless Steel Heats Up. Hot rolling of sections is the most productive technology of manufacturing long bars. Once the mill is set-up and ready for the production process, it can hot roll profiles in huge amounts with high productivity. In general, the temperature rises above 1.100 degrees Celsius.

Coiling – Coiling is the process of winding flat material while it is still hot.As it exits the extrusion rollers at the mill immediately after it has been formed. Coils – Sheet metal rolled from slab or ingot that has been wound into coiled roll.Coils are considered the most efficient way to store and transport sheet metal.

Multi-roll cold mill stands are described using different terms depending on their type and manufacturer: 12 and 20 roll stand Z-High® S-High. Multi-roll cold rolling mills are used to process high grade steel strip and non-ferrous metal strip. In order to prevent whipping of the work rolls, they are supported by means of intermediate
Rolled products are arranged in increasing minimum tensile strength (Rm0.2), which is indicated in the marking. The marking also contains the following information: H – high-strength flat-rolled products for cold forming; С – cold-rolled products; D – hot-rolled products; Т (nnn) – the minimum tensile strength in MPa.
