Choosing Between Hot Rolled Steel And Cold Rolled Steel

It is crucial to know the distinctions between Hot Rolled Steel (or Cold Rolled Steel) when you’re looking at the steel products. Each has its own advantages and disadvantages, so choosing the right type of steel will help you save money and time. In addition, cold-rolled metal is more uniform in its grain and finish than hot-rolled steel. This can cause it to shrink or warp.

The main characteristic of steel is its capacity to withstand the forces that are imposed on it. The graph of stress-strain (Fig. 1) illustrates this property. There are two kinds of yielding behavior for cold-formed steel sheets: gradual yielding and sharp yielding. The yield strength of each depends on the distribution of yield strengths and tensile strength in virgin material.

There are several levels of hardness available for cold-rolled steel sheets. Full hard is the toughest condition. Other conditions include half hard, quarter-hard, or skin-rolled. The full hard condition reduces the thickness of the steel by up to 50%. The other three conditions cause a less drastic reduction in thickness. Skin-rolled steel, also known by “skin pass” has the reduction in thickness of half to one percent.

What is Cold Rolled Steel, the cold Rolled Steel is more precise in dimensional measurements than hot-rolled steel. The process of cold-rolling increases the steel’s strength by as much as 20%. Cold-rolled steel is more flexible and has a superior surface quality than hot rolled steel. Cold-rolled steel is suitable for high-stress situations.

While hot-rolled steel may be processed at high temperatures, cold-rolled steel is able to be cooled at room temperature. The bluish tint of hot-rolled steel is more common. It isn’t equipped with many of the characteristics of cold-rolled steel, for instance its greater ability to take on different forms. However, the advantage of hot-rolled steel is the price.

Hot-rolled steel is shaped by pressing steel at a high temperature above its recrystallization temperature. It shrinks slightly when it cools. This allows it to be cut easily in larger sizes. Hot-rolled steel is cheaper than cold-rolled steel and tends to be more flexible to work with since it doesn’t require heating. Hot-rolled steel has fewer tolerances.
