Cold rolled steel is hot-rolled steel that has undergone additional processing.

Cold rolled steel is hot rolled steel that has undergone additional processing to improve its dimensional and mechanical properties. During the cold rolling process, cooled hot rolled steel passes through another series of rollers at room temperature. Since the material is no longer hot and malleable, a significantly higher amount of pressure is required to compress it into the desired shape.

Cold rolled steel is hot rolled steel that has undergone additional processing to improve its dimensional and mechanical properties. During the cold rolling process, cooled hot rolled steel passes through another series of rollers at room temperature. Since the material is no longer hot and malleable, a significantly higher amount of pressure is required to compress it into the desired shape. While this process can be more labor-intensive and expensive than the hot rolling process, it can achieve tighter dimensional tolerances and better surface qualities.

 

Benefits of Cold Rolled Steel

 

Compared to hot rolled steel, cold rolled steel offers a variety of advantages, such as:

 

• Greater strength: Cold rolled steel can exhibit strength up to 20% greater than that of hot rolled steel, which makes it more suitable for use in high-stress applications.

 

• Better surface finishes: Parts and products made from cold rolled steel generally have a smooth and shiny surface that is free of rust and scale.

 

• Higher precision: Unlike hot rolled steel, cold rolled steel does not shrink after the forming process. This quality allows for the creation of highly precise components that require little to no secondary processing.

 

Applications of Cold Rolled Steel

 

Cold rolled steel is often used for applications that require tighter tolerances and better surface finishes. Typical parts and products include:

 

• Aerospace structures
• Home appliances
• Metal furniture
• Strips, rods, bars, and sheets
• Mechanical Components

UNIQUE PROPERTIES OF COLD ROLLED STEEL

Cold Rolled Steel, often abbreviated as CR or CRS, is known for being extremely ductile. Additionally, it is formable for moderate draw applications, as well as being non-shrinking and non-creeping at ambient temperatures. 

Most often, you'll find details about Cold Rolled Steel as it compares to Hot Rolled Steel. Here are a few of the key differences between the two products: 

• Strength — Cold Rolled Steel can exhibit up to 20% greater strength than Hot Rolled Steel, making it more suitable for high-stress applications. 
• Precision — Cold Rolled Steel does not shrink after the forming process, allowing for the creation of precise components that require little to no secondary processing.
• Surface — Cold Rolled Steel generally has a smoother and shinier surface, free of rust and scale. 

COMMON COLD ROLLED STEEL PRODUCTS

With better surface characteristics and fewer imperfections, Cold Rolled Steel is most commonly used for precise applications where appearances are important. In addition, because of its tight size tolerance and excellent machinability, CRS is used across a wide variety of industries.
