The steel of Steel Plate comes in many grades, specifications, shapes, and finishes - the World Steel Association lists over 3,500 different grades of steel, each with unique properties. The various types mean that steel can by widely used in infrastructure, appliances, vehicles, wind turbines, and many more applications.

Optimizing steel's properties for each application goes beyond changing the chemical composition, however. The manufacturing processing of steel can also have a significant impact on steel products - even when the grades and specifications are the same. One key distinction among pre-fabricated steel products is the difference between hot rolled and cold rolled steel.

It's important to note that the main difference between hot rolled and cold rolled steel is one of process. "Hot rolling" refers to processing done with heat. "Cold rolling" refers to processes done at or near room temperature. Although these techniques affect overall performance and application, they should not be confused with formal specifications and grades of steel, which relate to metallurgical composition and performance ratings. Steels of different grades and specifications can be either hot rolled or cold rolled - including both basic carbon steels and other alloy steels.

It may seem obvious, but some types of steel are better suited for certain applications. Knowing which to use can help avoid over-spending on raw materials. It can also save time and money on additional processing. Understanding the differences between hot and cold steel is integral to choosing one over the other.

Hot rolled steel including Hot Rolled Steel Plate and Hot Rolled Steel Coil 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.
