Hot rolled steel is steel that has been roll-pressed at very high
temperatures—over 1,700˚F, which is above the re-crystallization
temperature for most steels. This makes the steel easier to form,
and resulting in products that are easier to work with.
To process hot rolled steel, manufacturers first start with a large, rectangular length of
metal, called a billet. The billet is heated and then sent for
pre-processing, where it is flattened into a large roll. From
there, it is kept at a high temperature and run through a series of
rollers to achieve its finished dimensions. The white-hot strands
of steel are pushed through the rollers at high speeds. For sheet
metal, rolled steel is spun into coils and left to cool. For other
forms, such as bars or plates, materials are sectioned and
Steel shrinks slightly as it cools. Since hot rolled steel is
cooled after processing, there is less control over its final
shape, making it less suitable for precision applications. Hot
rolled steel is often used in applications where minutely specific
dimensions aren't crucial. Railroad tracks and construction
projects often use hot rolled steel.
Hot rolled steel can often be identified by the following
- A scaled surface—a remnant of cooling from extreme temperatures
- Slightly rounded edges and corners for bar and plate products (due
to shrinkage and less precise finishing)
- Slight distortions, where cooling may result in slightly
trapezoidal forms, as opposed to perfectly squared angles
What are the benefits of hot rolled steel?
Hot rolled steel typically requires much less processing than cold
rolled steel, which makes it a lot cheaper. Because hot rolled
steel is allowed to cool at room temperature, it's essentially
normalized—meaning it's free from internal stresses that can arise
from quenching or work-hardening processes.
Hot rolled steel is ideal where dimensional tolerances aren't as
important as overall material strength, and where surface finish
isn't a key concern. Where surface finish is a concern, scaling can
be removed by grinding, sand blasting, or acid-bath pickling. Once
scaling has been removed, various brush or mirror finishes can also
be applied. Descaled steel also offers a better surface for
painting and other surface coatings.
