CR COILS and Sheets. C. R. Sheets/ Coils. CR sheets or cold rolled sheets are hot rolled products which provides a superior surface finish, with improved physical properties of the steel, such as high formability, high strength, excellent dent resistance, good magnetic properties, tensile strength, and workability and welding properties.
Cold rolled steel is stored and sold in coiled form after rolling. Steel comes in many grades, specifications, shapes, and finishesthe World Steel Association lists over 3,500 different grades of steel, each with unique properties. The various types mean that steel can by widely used in infrastructure, appliances, vehicles, wind turbines, and many more applications.
Sep 11, 2014 · 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 steels 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.

Difference Between Hot Rolled and Cold Rolled Steel Coil. Customers often ask us about the differences between hot rolled coil and cold rolled coil. There are some fundamental differences between these two types of metal. These differences relate to the ways these metals are processed at the mill, and not the product specification or grade.
Hot rolled steel coils are then shipped to service centers, like Metalwest, to process and distribute to our customers. However, hot rolled steel can be sent through other processes, including pickle and oiling, cold rolling, and many more to create other forms of steel.
Apr 06, 2018 · Hot rolled dry sheets and coil are a darker grey than most other steel types and have a silvery blue, almost purple strip along both sides. The color of the strip makes the steels surface appear as if it is still hot to the touch.
Compared to hot rolled steel, cold rolled steel has a nearly 20% increase in strength through the use of strain hardening. Its through a series of breakdown, semi finishing, sizing, semi roughing, roughing, and finishing that cold rolled steel shapes can be created. Cold rolling steel allows for
Apr 24, 2017 · Hot Rolled Steel Vs. Cold Rolled Steel. Updated April 24, 2017. Cold rolled steel is made by passing the steel through a number of rollers after the metal has cooled from initial production. Cold rolled steel in normally available in four typescommercial steel, drawing steel, extra deep drawing steel, and extra deep drawing steel plus
Although hot rolled steel plate products are known for looser tolerances than cold rolled steel alternatives, a bit of play may be appropriate in your specific application. For instance, joinery and other construction endeavors often employ wood beams that exhibit some variance in size; using hot rolled brackets may make the build process a bit
Hot rolled steel is turned into a coil of steel while the temperature is above 1700 degrees Fahrenheit. This process makes the material more malleable, making it easier for the material to be rolled. Because of its malleability, hot rolled steel is used as a material for structural components.
In addition to different sizes of steel coils, there are also two different primary typesCold rolled steel coils. Cold rolled steel is a more finished product that not only looks nicer, having a more finished surface but is also more durable than is hot rolled steel. This steel is
This post will explain the four different steel forming processhot rolled steel, cold rolled steel, forged steel and cast steel. And discuss the advantages and applications of each steel forming process, and will tell you how to buy the right steel materials in great quality and price.
