    Product Description

    Thick Mild Carbon Steel Welded Pipe

    Carbon Steel Welded Pipe 4140 :4140 steel, this steel has good processability, processing deformation is small, fatigue resistance is quite good, such as hardenability steel, 4140 heat treatment after better strength and good comprehensive mechanical properties, good process, high yield.

    The maximum use temperature is 427 degrees Celsius, 4140 strength, high hardenability, good toughness, small deformation during quenching, high creep strength and lasting strength at high temperature.

    It is used to manufacture forgings requiring higher strength and larger tempering cross-section than 35CrMo steel, such as large gear for locomotive traction, supercharger transmission gear, rear shaft, connecting rod and spring clamp with great load, and can also be used for drilling pipe joints and fishing tools in oil deep Wells below 2000m, and can be used for bending machine molds.

    Advantage

    Good wear resistance

    Good processability, good corrosion resistance,good oxidation effect of easycoating, and good weldability.

    Good weldability

    Wear-resistant steel has high wear resistance and good impact resistance. It can be cut. Bending, welding, etc. It can be connected with other structures by welding, plug welding, etc. Bolt connection, etc.

    High hardness

    Carbon steel also typically contains small amounts of silicon, manganese, sulfur, and phosphorus. In general, the higher the carbon content, the greater the hardness of the carbon steel, the higher the strength.

    Application

    1、 Construction field:Carbon steel pipes are widely used in the construction field, commonly used in building structures, underground water pipes, heating pipes, etc. Carbon steel pipes are widely used due to their low price, strong compressive strength, and good corrosion resistance. In building structures, carbon steel pipes are used as materials for supporting frames, suspension rods, and other components to ensure the stability and safety of the building structure.

    2、 Manufacturing field:Carbon steel pipes can be used as materials for manufacturing mechanical components and are commonly used for making bearings, gears, screws, etc. Carbon steel pipes have the characteristics of high strength and good wear resistance, making them able to withstand large loads and friction, and are therefore widely used in the manufacturing field.

    3、 Chemical industry:Many pipes and fittings are required in the chemical industry, and carbon steel pipes, as a commonly used pipe material, are widely used in the chemical industry. Due to the corrosive nature of chemicals, selecting appropriate pipe materials can improve the service life and safety of the entire pipeline system. Carbon steel pipes have excellent corrosion resistance, even in acidic and alkaline environments.

    4、 Energy sector:In the energy field, carbon steel pipes are mainly used to transport some media, such as oil, gas, water, etc. Due to the high strength and good wear resistance of carbon steel pipes, they can ensure the hydraulic and sealing performance of the pipeline, thereby making the transportation process safer and more stable.
