Cold coils are made from hot-rolled coils as raw materials and rolled at room temperature below the recrystallization temperature. They include plates and coils. Those delivered in sheets are called steel plates, also called box plates or flat plates; they are very long and Those delivered in rolls are called steel strips, also called coils.Performance: Mainly using low carbon steel grades, requiring good cold bending and welding properties, as well as certain stamping properties.
AISI 1045 steel coils is a high-strength high-quality medium carbon steels with good weldability, good machinability and impact performance, and it is hot-pressed and cold-pressed into coils with good wear resistance and toughness. 1045 steel coil is widely used in all industrial applications that require higher wear resistance and strength, and are also used in the manufacture of mechanical parts that require high strength.

CR Cold Rolled Steel Coil
The advantages of using 1045 cold rolled carbon steel include:
- Offers excellent tensile strength and hardness, making it suitable for demanding applications.
- It can be easily machined into various shapes and forms, allowing for efficient manufacturing processes.
- When techniques for joining medium-carbon steels are used, AISI 1045 is suitable for welding.
- 1045 cold rolled carbon steels is known for its ferrite and pearlite microstructure, which consists of alternating lamellae of ferrite and cementite (iron carbide). This unique structure contributes to its wear-resistance properties. The carbides present in the pearlite structure are responsible for providing enhanced wear resistance, making 1045 cold rolled carbon steels suitable for components subjected to wear and friction.
Scope of cold rolled steel Application
The following are the application areas of AISI 1045 carbon steels:
● Bolts
● Studs
● Gears
● Axles
● Shafts
● Machine parts.
