The Difference between Cold Rolled Carbon Steel and Cold Rolled Normal Steel

Cold rolling is a method of passing the metal through rollers at temperatures below recrystallization (400 O C to 700O C). The metal is crushed and compressed, increasing its yield strength and hardness. Metal strip cold rolling is a unique section of the metalworking business. 

What is cold rolled carbon steel?

Carbon steel is a generic phrase for any hot-rolled steel that isn't categorized as 'low-alloy' or 'high alloy.' In its broadest sense, the term refers to basic steel shapes such as channels, edges, squares, etc.

All steel framed when it is cold at room temperature is referred to as cold-rolled. These shapes are usually unmistakably progressively accurate in size and consistency, and they will retain a significant amount of remaining pressure unless they are heat-rewarded after frame.

Uses/advantages:

● Cold rolled carbon steel, also known as mild steel, is widely used to construct buildings and bridges, gears, axles, shafts, pipelines, railroads, couplings, refrigerators, automobiles, and washing machines. Blades, cutting tools, punches, springs, dies, and high-strength wire is all made of high carbon steel, which has a substantially higher tensile strength.

● Cool contoured latches and jolts are examples of its fundamental applications. It is frequently used to treat toughened or hardened conditions.

Disadvantages:

● Carbon steel is tough to work with because of its strength. It is difficult to bend and mold into diverse shapes, limiting its use in several applications. Other forms of steel are more resistant to rust and corrosion than carbon steel.

What is cold rolled steel?

Cold rolled steel is essentially hot rolled steel that has been annealed, or temper rolled after being allowed to cool at room temperature. Steel produced by cold rolling has tighter tolerances and a wider variety of surface finishes than steel produced by hot rolling.

Uses/advantages:

● Metal furniture, structural elements, home appliances, water heaters, metal containers, fan blades, frying pans, and computer cabinets can be manufactured using cold rolled steel.

● Cold rolled steel has a strength of up to 20% greater than hot rolled steel, making it more suitable for high-stress applications.

Disadvantages:

● Cold rolled steel is more expensive than other steel because of its advantages. Furthermore, because cold rolled steel is more difficult to manipulate, equivalent processes take longer and cost more.

Wrapping it up!

Now that you have understood the pros and cons of cold rolled normal steel and carbon steel, you may wonder about the best place to get these types of steel. That is the first thing that comes to a consumer's mind after learning about a specific thing. Of course, there are plenty of cold rolled steel suppliers in the market. But, JSW Steel is a preferred choice for consumers with its high flatness, thickness control, and mechanical qualities.
