Hot rolled steel and cold rolled steel are some of the most widely manufactured steel types in the world. They make the I-beams we see in buildings, railroad tracks, automotive parts, tooling equipment, and are a part of everyday objects we come across. There's a simple difference between hot and cold rolled steel that makes a huge impact on the size, quality, strength and appearance of the steel. Learn why hot rolling and cold rolling steel makes a huge difference on the type of steel that is produced, why there is such a big difference in the cost of making each, the yield and tensile strength of the steel, and other physical characteristics.

1. The Difference Between Hot
Rolled Steel & Cold Rolled Steel

2. When it comes down to
making cold rolled steel
and hot rolled steel , the
process is quite similar.

3. They are both
made from the
same materials.

4. They go through a
similar manufacturing
process, except for one
crucial part.

5. Cold rolled steel is rolled, or
passed through at least two
rollers at room temperature
until it forms the desired
shape and dimensions.

6. And hot rolled steel is
rolled at or above its
recrystallization
temperature, which is at
1,700 °F.

7. Why is steel rolled? Why at different
temperatures?

11. Appearance

12. Dimensions

13. Strength

14. Cost
*This varies on many factors, including
whether the steel that is being hot rolled is
required to be reheated or not, and
whether the steel is pickled and oiled.

15. I-beams, railroad tracks, and materials needed
in large quantities.

16. Practical Uses
Tooling and machining products, automotive
parts, anything that requires more strength.
