S45C Carbon Steel Seamless Tubes

S45C Carbon Steel Seamless Tubes are tubes made of carbon steel with a chemical composition of carbon (C): 0.42-0.48%, Silicon (Si): 0.15-0.35%, Manganese (Mn): 0.60-0.90%, Phosphorus (P): ≤ 0.030%, Sulfur (S): ≤ 0.035%. These tubes are used for various applications, including machinery parts, structural materials, and fluid conveyance systems. They are commonly used in the automotive, construction, and manufacturing industries due to their high strength, durability, and resistance to corrosion.

The following are some specifications of S45C Carbon Steel Seamless Tubes:

1. Size: The size  can range from 6mm to 720mm in diameter and up to 100mm in wall thickness.

2. Material: These tubes are made from high-quality S45C carbon steel, which has a high carbon content and excellent heat treatment properties.

3. Surface finishing: The tubes are available in a range of surface finishes such as black, oiled, pickled, and bright.

4. Standards: comply with various international standards such as ASTM, EN, JIS, and GB.

5. Characteristics: These tubes have excellent mechanical properties such as high strength, toughness, and wear resistance. Plus, they are easy to machine and have excellent weldability.

Production Process

1. Raw material preparation: The first step in the S45C carbon steel seamless tube production process is to prepare the raw materials. The manufacturers carefully select high-quality raw materials to ensure that the finished product meets the required specifications.

2. Heating and forging: Once the raw materials are ready, they are heated in a furnace to a high temperature and then forged into the desired shape. This process helps to improve the strength and hardness of the carbon steel.

3. Cold drawing: After forging, the S45C carbon steel is subjected to a cold drawing process where it is pulled through a die to create a tube with a precise diameter and thickness.

4. Annealing: To further improve the mechanical properties of the S45C carbon steel and make it more malleable, the tube is annealed at a specific temperature for a set amount of time.

5. Cutting and finishing: The final step is to cut the tube to the desired length and finish it to remove any rough edges or impurities.
