Cold Rolled Sheet
What Is Cold Rolled Steel?
Cold rolled steel is a hot-rolled steel that undergoes additional processing to improve its size and mechanical properties.
During cold rolling, the cooled hot-rolled steel passes through another series of rolls at room temperature.
Because the material is no longer hot and malleable, more pressure is needed to compress it into the desired shape.
Although this process is more labor-intensive and more expensive than the hot rolling process, it can achieve more accurate dimensions and better surface quality.
What Is Rolling?
Rolling is a kind of metal forming process; which uses a series of rollers to change shape, improve uniformity and enhance the mechanical properties of materials. Rolled steel can be divided into two types–hot-rolled steel and cold-rolled steel–which have different characteristics and are suitable for different applications. When selecting rolled steel materials for a project, it is important to understand the differences between the two types and how they affect their performance.
Differences Between Cold Rolled Steel & Hot Rolled Steel
The main difference between hot-rolled steel and cold-rolled steel lies in their processing methods.
Hot-rolled steel is rolled above the recrystallization temperature of the material, while cold-rolled steel is rolled below the recrystallization temperature of the material. Cold-rolled steel is essentially hot-rolled steel and is further processed in cold-rolled materials. Different grades and specifications of steel can be hot-rolled or cold-rolled. The difference between cold-rolled steel and hot-rolled steel is mainly in the following aspects:
Surface quality: the edges and surfaces of hot rolled steel are often rough and need decarburization or other treatment before they can be used in subsequent production operations. In contrast, the surface of cold-rolled steel is usually bright and smooth and can be directly used in production operations.
Material hardness: the steel produced by cold rolling process has higher strength and hardness than that produced by hot rolling process.
Internal stress: the higher the strength and hardness of the material brought by the cold rolling process, the greater the internal stress. These stresses must be eliminated before processing the material; otherwise, the final part or product may warp.
In conclusion, when evaluating the steel selection of a project, it is important to keep in mind that some materials are more effective than others in some uses.
Knowing which steel provides the right performance for a particular application can prevent excessive spending on raw materials and save time in the long run.
