Cold drawn carbon steel flats and hot rolled carbon steel flats differ primarily in their manufacturing processes and resulting properties. Cold drawn flats are produced by pulling the steel through a die at room temperature, which enhances their surface finish, dimensional accuracy, and mechanical properties, making them stronger and more precise. They are ideal for applications requiring tight tolerances and high strength, such as automotive and machinery parts. On the other hand, hot rolled flats are made by heating the steel to high temperatures and passing it through rollers, which results in a rougher surface and larger dimensional tolerances. While hot rolled flats are less precise, they are more cost-effective and suitable for general-purpose applications like construction and large-scale projects.
