Cold rolled steel is a type that is slowly cooled to create a uniform surface and reset the grains. This allows it to be easier to shape and form steel as opposed to hot rolled steel that is heated to over 1200 degrees Fahrenheit. Cold Rolled Steel is stronger than hot-rolled steel and easier to work with.
The American Iron and Steel Institute (AISI), has published a variety of design manuals and specifications for cold-formed steel. These manuals and specifications were designed to assist in the design of structures. Cold-rolled steel is a type of structural steel. It is used in a variety of applications. Its high tensile strength as well as low yield strength make it a great material for building.
The primary difference between hot-rolled and cold-rolled steel is the method in which it is processed. Hot-rolled steel is created by high temperatures in a mill process, while Cold Rolled Steel undergoes this process at a much lower temperature. Both of these processes impact the steel’s overall performance as well as its application. Hot-rolled and Cold-rolled steel have different grades and specifications that relate to the metallurgical composition and performance ratings.
What is Cold Rolled Steel, the cold-rolled steel has an excellent surface finish and requires very little secondary processing. It does not shrink after the formation process, unlike hot-rolled steel. This makes it possible to produce components of very high precision. It is also easier to work with than hot rolled steel. Therefore, Cold Rolled Steel is more flexible in production processes.
The production of hot-rolled steel involves an process that involves rolling steel at temperatures that are high, typically more than 1000 degrees Fahrenheit. This process permits easier shaping and larger sizes, however it also creates residual stresses. Steel that is hot-rolled shrinks a bit when it cools down and results in less control over its size and shape.
It is less expensive than Cold Rolled Steel and requires less processing than cold-rolled. Since the steel is cooled slowly, it offers better workability. This process creates less stress on the internal structure which makes it more pliable to form. Cold-rolled steel is stronger, however it is more expensive.
Cold steel is produced by rolling it at room temperature. This increases steel’s strength by up to 20%. It has a grayish finish and is smooth to the feel. Cold Rolled Steel has a more precise dimension because it has been chilled. This makes it ideal to use in high stress situations.
