Advantages and Disadvantages of Cold Rolled Steel

 Hot rolled steel when cooled at room temperature or below the recrystallization temperature of steel, is converted into cold rolled steel, which is then used by other industries like construction, automobile, and the making of various home appliances. Cold rolled steel is better as compared to hot rolled steel and offers various advantages –

1. Higher Strength: Cold rolled steel is cooled at room temperature, which makes it stronger for use as using heat to roll the steel can make it weak and less efficient for tough projects. Generally, it has 20% more strength than hot rolled steel, which helps in meeting the higher cr steel grades.  

2. Improved Surface Quality: Hot rolling involves higher imperfection due to the heating process in rolling. Cold rolling provides smooth finishing to steel, making it more usable for cars, furniture, and other home appliances. 

3. Greater Tolerance: The cold rolled steel is thinner than hot rolled steel but has greater tolerance, which means reduced thickness increases the toughness, hardness, and strength of the steel sheets or coils. 

4. Improve Processing: CR steel is more suitable for the further manufacturing process in various industries like construction, automobiles, etc. JSW Cold Rolled Steel is one of the top suppliers of cold rolled coils and cold rolled sheets, and its quality is unbeatable. 

5. Improved Yield Point: Cold rolling can improve the yield point of the steel as this process makes the steel produce large plastic deformation. 

6. Higher Accuracy: Cold rolled steel sheets do not shrink or change their shape after formation. Hence, it provides higher precision. 

Some of the disadvantages of cold rolled steel:

1. Higher Price: Since cold rolled steel has advantages over hot rolled steel and requires more time in its processing, it is more expensive. Moreover, the tools and equipment used in cold processing are expensive to purchase. 

2. Low Malleability: The cold rolled steel has low malleability i.e., it is very hard which makes it difficult to change its shape and convert it into other useful things. 

3. High Pressure Required: Because of the great tolerance capacity and higher strength, very high pressure is required in cold working. 

4. Nonuniform Impurities Distribution: In cold pressing, the impurities are not uniformly distributed on the surface of the steel sheets. 

You should be aware of all the advantages and disadvantages of using cold rolled steel before using it for any purpose. You should always confirm the credibility of the company and the grading of the products before buying. Moreover, JSW Cold Rolled Steel is a well-known company in India, serving a versatile range of hot and cold rolled steel to various other industries worldwide.
