Types of Cold Rolled Carbon Steel
Cold rolled carbon steel comes in a variety of carbon content levels:
Low-Carbon Steel—Also known as mild steel, contains less than .3% of carbon. It is highly formable, making it effective for applications that require a great amount of bending and forming.
Medium-Carbon Steel—Contains anywhere from .3% to.6% carbon, which makes it stronger and more durable for applications such as automotive manufacturing.
High-Carbon Steel—Consists of .61% to 1.5% carbon, which changes its physical properties significantly. With higher carbon content, the steel becomes stronger and harder than the lower carbon steels; however, this material exhibits less ductility.
Additionally, the cold rolling and annealing process that the steel undergoes produces different levels of hardness:
Dead soft
¼ Hard
Half Hard
Full Hard
The specific hardness required depends on the particular application that the material will be used for.
Premium Steel Sales stocks and sources a large amount of cold rolled steel, including master coils that we can slit to width and pre-cut sheets, that will fit your specific application. We can help you choose the proper grade and hardness level of cold rolled steel for your specific need based on the fabrication method and type of environment in which the material will be used. We also offer various processing services, including slitting to width (narrow slitting is also available), coil spinning for inspection, and both; cut to length and multi-blanking capabilities.

Cold rolled carbon steel is hot rolled steel that has been further processed. Once hot rolled steel has cooled, usually at or below its recrystallization point, it is then annealed and re-rolled at room temperature to achieve more exact thickness, higher strength & hardness, and better surface qualities. Besides altering mechanical properties, the cold rolling process produces steel with tighter tolerances and greater dimensional accuracy than hot rolled steel. It also tends to be more available in lighter gauges and is better suited for applications that require a more visually appealing finish.

Cold Rolled Carbon Steel Applications：
Because of its excellent dimensional tolerance and press formability, cold rolled carbon steel is typically used in a wide range of structures and applications such as machinery framing, ductwork, construction, and other varieties of industrial applications.
Typically, carbon steel is used where it is not exposed to external elements due to the risk of the material oxidizing. Cold rolled carbon steel is best suited for more technically precise applications, such as electronics, appliances, automotive use, office furniture, and construction.
Cold rolled coil type:
Cold-rolled coil and plate products can also be divided into 3 categories according to application fields:
SPCC and SPCCT are commonly used in refrigerators, cabinets, distribution boards, and rollers; SPCD is used for automobile floor and roof panels; SPCE and SPCF are used for automobile fenders and side panels, and SPCG is used for automobile interior panels and deep-drawn parts.
Better processability for special purposes: NSCC is used for car doors, hoods, shallow drawn parts, NSC270D NSC270E is used for car side panels, floors, deep drawn parts, car side panels, NSC270F is used for car side panels, NSC270G is used for cars Oil pan, high top, extra deep drawn part
High-strength steel: NSC390N, 440N, 490N, 540N, 590N are used for reinforcements, components, pillars and bumpers, NSC340BH is used for hood outer panels, door outer panels and trunk lid outer panels, etc.
