Cold Rolled Carbon Steel Coil

Cold rolled low carbon steel coil is a steel coil with low carbon content. It is made of hot rolled coil as raw material and rolled at room temperature below the recrystallization temperature. Cold rolled low carbon steel coil is obtained by cover annealing before rolling.

Low carbon cold-rolled coil steel is a premium modification of high-quality rolled metal, manufactured from cold-rolled hot-rolled steel through special shafts on machine tools. This type of rolled products has improved technical performance, reliability and service life compared to hot rolled products. Rolled mild steel coils is widely used to manufacture various metal structures and is ideal for transverse/vertical cutting, bending, welding, and stamping.

GNEE STEELL has extensive experience and a good reputation in the European rolled products market. We sell cold rolled steel coils from leading manufacturers. Rolled steel is manufactured as per stringent framework of various norms and standards and is therefore of extremely high quality.

Material:

①Carbon steel (different grades such as CQ, DQ, DDQ, EDDQ, etc.)

②Alloy steel (HSLA, high-strength steel, ultra-high-strength steel, etc.)

There are many materials of cold-rolled sheet, but its classification can basically be classified into two categories: carbon steel and alloy steel according to the two major characteristics of chemical composition and mechanical properties.

Features:

①Good surface quality and good stamping performance, so it can be widely used in the automotive industry, food cans, aerospace, precision instruments and many other fields.

② With good heat resistance, the cold-rolled sheet processed by the rolling process is generally more heat-resistant than the ordinary sheet.

③It has good heat reflectivity. Cold-rolled steel processed by processing technology under normal temperature crystallization has stable surface properties, and can emit heat well under the condition of heating to protect the plate.

SAE / AISI 1008 (UNS G10080) is a low-carbon steel type with enough manganese and phosphorus to be considered a low-alloy steel. It has excellent weldability with various commercial welding methods and is quickly soldering. This type of steel has higher strength than SAE/AISI 1005, providing good ductility in thicker gauges. Additionally, adding certain elements, such as aluminium, helps improve the hot-rolled finish during production. Overall, SAE/AISI 1008 offers ease of forming due to its excellent workability and is highly suitable for processes requiring moderate degrees of strength or cold bending operations.

We can also provide steel with sae 1008 material, welcome to inquire for details.

SAE – AISI 1008 Equivalent

1. The cold-rolled coil products have accurate dimensions and uniform thickness. The thickness difference of the coils generally does not exceed 0.01-0.03 mm or less, which can meet the requirements of high-precision tolerances.

2. Ultra-thin strips (up to less than 0.001 mm) that cannot be produced by hot rolling can be obtained.

3. The surface quality of cold-rolled products is superior, without pitting, hot-pressed iron oxide,

etc., commonly used in hot-rolled coils, which can produce coils with different surface roughness (smooth or pitted)

According to user requirements. The surface is rough, etc. to facilitate the processing of the next process.

4. Cold-rolled plates have good mechanical properties and process properties (such as higher strength, lower yield limit, good deep drawing performance, etc.).

5. High-speed rolling and full continuous rolling can be achieved with high productivity.

The production process of cold rolled coils varies slightly according to the raw materials and the varieties and specifications of the products. Here is the making process of cold rolled steel.

Raw Material (Hot rolled steel)- Pickling – Cold Rolling – Degreasing – Annealing – Rolling up – Packaging

1. Pickling. Hot-rolled coils pass through a pickling line to remove oxide scale on the surface by using hydrochloric acid solutions. Through the pickling process, there will be fewer surface flaws left.

2. Cold rolling. Pickled coils are rolled to a specified thickness in the cold-rolled mill.

3. Annealing. After removing the lubricant oil and contaminants by electrolytic cleaning, the coil will go through the continuous annealing process. It aims to make steel products with high tensile strength.

4. Rolling up into coils and then packaging for sale.
