What is The Difference Between Hot Rolled (HR) & Cold Rolled (CR) Steel?

This article will help you understand the main differences between cold-rolled steel (CRS) and hot-rolled steel (HRS). Anyone working in the metal fabrication business must be aware of the distinctions between these two widely used steel-making methods.
That's exactly how it sounds.
Hot rolled steel is an important material in many fields. It is made between 1500°F and 1800°F, which is a high amount of red or orange heat. This high warmth helps formation happen quickly and significantly. But as the hot steel cools and shrinks, the size tolerance needs to be able to change. HR Coil Wholesalers are very important for getting this important product to people who need it.
On the other hand, cold rolled steel shapes up at a lower temperature, usually between 400°F and 900°F, which is called a "black heat." The process takes longer and puts more stress on the rollers, but when the steel cools to room temperature, it shrinks less, which makes the limits tighter. This level of accuracy is highly respected across all fields, which shows how important HR Coil Wholesalers is as a supplier of cold-rolled steel.
It is also thought that cold rolling can help strengthen the surface of bars or sheets. This process may have a small and usually unimportant hardening effect on most steel types, but in some cases it can make the steel last longer and be less likely to wear down. HR Coil Wholesalers are very important because they make sure that both hot and cold-rolled steel are available for all kinds of industrial uses.
Hot Rolled Steel vs. Cold Rolled Steel
It is very important to know the differences between the two types of rolled steel and how those differences affect how well they work when picking a material for a project. See the "Hot Rolled vs. Cold Drawn" table below for a side-by-side look at the two:
Hot Rolled Steel
Cold Rolled Steel
Process
Rolled at high temperatures and allowed to cool
Hot rolled steel has been further processed by being allowed to cool at room temperature and annealed, or temper rolled.
Characteristics
• Scaly finish
• Rounded edges and corners
• Slight distortions
• More malleable
• Increased ductility and toughness
• Closer dimensional tolerances
• A wider range of surface finishes
• Up to 20% stronger than HRS
Advantages
• Cheaper than CRS
• Normalized from cooling
• Free from internal stresses
• Smooth, finished surfaces
• Closer tolerances
• Harder and stronger than HRS
• Aesthetically pleasing finish
Applications
• Structural components (railroad tracks, I- beams)
• Metal buildings
• Agricultural equipment
• Automotive Frames • Home appliances
• Metal furniture
• Aerospace components
• Automotive parts
