    General Properties of 347H Stainless Steel Pipes


    The general properties of 347H stainless steel pipes are similar to those of 347H stainless steel tubes, as they both belong to the same alloy. Here are some key properties of 347H stainless steel pipes:


    1. Corrosion resistance: 347H stainless steel pipes offer excellent resistance to corrosion in various environments, including acidic, alkaline, and chloride-containing solutions. They have a high resistance to intergranular corrosion due to the addition of niobium.


    2. Heat resistance: These pipes have good high-temperature strength and can withstand elevated temperatures up to 1000°C (1832°F). They are commonly used in applications involving intermittent heating and cooling cycles.


    3. Weldability: 347H stainless steel pipes can be easily welded using conventional welding methods. They offer good weldability and can be welded without the risk of intergranular corrosion.


    4. Mechanical properties: The mechanical properties of 347H stainless steel pipes include high tensile strength, good yield strength, and excellent toughness. They exhibit good ductility and can be formed into various shapes.


    5. Machinability: 347H stainless steel pipes have good machinability. They can be easily machined using conventional methods, although the presence of high carbon content may reduce tool life.


    6. Physical properties: The density of 347H stainless steel pipes is around 7.96 g/cm³. They have a melting point of approximately 1454°C (2650°F) and a thermal conductivity of 16.3 W/m·K.


    Specific properties may vary depending on the manufacturer and the specific grade of 347H stainless steel pipes. It is recommended to consult the manufacturer's datasheet or technical specifications for more accurate and detailed information.

    Heat Treatment of 347H Stainless Steel Pipes


    The heat treatment of 347H stainless steel pipes is similar to that of 347H stainless steel tubes. The most common heat treatment processes for 347H stainless steel pipes include annealing and solution annealing.


    1. Annealing: Annealing is typically performed by heating the pipes to a temperature range of 1010°C to 1120°C (1850°F to 2050°F) and then slowly cooling them in a furnace or air. This process helps to soften the material, improve ductility, and relieve any residual stresses from previous processing operations.


    2. Solution Annealing: Solution annealing is commonly performed on pipes that have been cold-worked or welded. It involves heating the pipes to a temperature range of 1010°C to 1120°C (1850°F to 2050°F) for a sufficient period of time, followed by rapid quenching in water or oil. This process helps to dissolve any carbides that may have formed during cold-working or welding, restoring the material's corrosion resistance and mechanical properties.


    After the heat treatment process, the pipes may undergo further processing steps such as pickling, passivation, and/or cold-working to achieve the desired final dimensions and surface finish.


    It is important to note that the specific heat treatment process and parameters may vary depending on the manufacturer's recommendations, the specific grade of 347H stainless steel, and the intended application of the pipes. It is recommended to consult the manufacturer's technical specifications or guidelines for the appropriate heat treatment for your specific requirements.


    Typical Uses


    Due to their excellent corrosion resistance and heat resistance, 347H stainless steel pipes are widely used in various industries, including chemical processing plants, oil and gas refineries, power generation, and other high-temperature applications.
