Hot rolled steel is steel that has undergone the rolling process at a temperature above its recrystallization temperature (usually ° F or greater). Compared to unprocessed steel, the processed material exhibits greater formability and workability, making it easier to work with in subsequent processing operations.

The hot rolling process starts with a large, rectangular slab of metal referred to as a billet. First, the billet is heated and compressed into a large roll. While still hot, it passes through a series of rotating rollers to achieve the desired dimensions. In sheet metal production operations, the rolled steel is then wound into coiled rolls and left to cool. In production operations involving other forms, the processed material is cut into the specified units and packaged.

Benefits of Hot Rolled Steel

Hot rolled steel offers several manufacturing advantages, such as:

• Lower cost: Hot rolled steel tends to be less expensive than cold rolled steel since it involves less processing.
• Better workability: As the hot rolling process occurs at elevated temperatures, the processed material is easy to form and shape.
• Little to no internal stress: The hot rolling process involves cooling the steel gradually, which allows the material to essentially normalize its structure and become free of internal stresses.

Applications of Hot Rolled Steel

Since hot rolled steel shrinks slightly during the cooling stage, there is a lesser degree of control over its final shape. For this reason, it is typically used in applications that do not require extremely tight tolerances, such as:

• Agricultural equipment
• Automobile parts (e.g., frames and wheel rims)
• Construction materials (e.g., I-beams)
• Railroad equipment (e.g., tracks and railcar components)

Wasatch Steel is a top provider of steel services across Utah, and we service numerous different types and classifications of steel. In particular, we provide steel created through both the common temperature-related processes: Hot rolled and cold rolled steel.

Both types of steel have their benefits and drawbacks, and it often depends on which type of project you&#;re looking to complete. Let&#;s look at the pros and cons of hot rolled steel, and how it might fit your next project.

Steelhighsen are exported all over the world and different industries with quality first. Our belief is to provide our customers with more and better high value-added products. Let's create a better future together.

What is It?

When steel is rolled out into a coil, it&#;s done at a varying range of temperatures. Often these are very high temperatures &#; anything over room temperature technically qualifies as &#;hot rolled&#; steel, though most of what you&#;ll see in this classification refers to steel heated up to at least 1,000 degrees Fahrenheit. This makes the steel relatively malleable compared with cold rolled steel, and there are several other differences as well.

Pros

There are a couple specific benefits offered by hot rolled steel:

• Price: Cold rolled steel is generally more expensive than hot rolled, mostly due to slightly stronger properties.
• Flexibility: Because of how high the temperatures are, hot rolled steel is more malleable. It can be cut or formed into nearly any shape needed, unlike cold rolled steel.
• Wide use: Because of this, there are tons of common uses for hot rolled steel. It&#;s most commonly made into sheet metal, and is perfect for projects where a little &#;give&#; is needed in metal.
• Time: Because of its ease of manipulation, many projects using hot rolled steel will take much less time than those with cold rolled steel.

Cons

There are also a few drawbacks to some project situations that you&#;ll want to be aware of with hot rolled steel:

• Durability: Hot rolled steel is weaker than cold rolled steel. This is due to the heat applied, which weakens the metal before it cools back down.
• Touch: Hot rolled steel is also generally much rougher to the touch. This is because of the cooling process involved, which can cause elements to settle in rougher places rather than a smooth finish.
