We offer These Stainless Steel 309H Flanges as per DIN, ISO, JIS or ANSI Standard.
High-Temperature Resistance: Stainless steel 309H is specially designed for high-temperature applications, withstanding temperatures up to 1000°C (1832°F) without losing its mechanical properties. This makes it suitable for use in furnaces and other industrial applications where excessive heat is a factor.
Easy to manufacture: Stainless steel 309H is easily weldable and manufacturable, making it easy to manufacture and shape to meet specific system requirements. This makes it a versatile material for flange design and various functions.
Strength and durability: Stainless steel 309H exhibits superior strength and toughness even at elevated temperatures. This ensures the reliability and durability of the flange in demanding applications where mechanical strength is important.
Oxidation Resistance: The high chromium content of stainless steel 309H provides exceptional oxidation resistance, even at high temperatures. This property helps prevent scale formation and maintains the integrity of the material in high-temperature oxidizing environments.
Corrosion Resistance: Stainless steel 309H contains high levels of chromium and nickel, providing excellent corrosion resistance in a variety of corrosive environments, including acidic and alkaline solutions. This makes it suitable for use in medicine, marine environments and other corrosives.
Stainless Steel 309H Flanges shave excellent mechanical qualities and are resistant to wear corrosion, and high temperatures, they are widely used in various industries. These flanges are widely used in the oil and gas, petrochemical, power generation, and aerospace industries. They play an important part in joining equipment, valves, and pipe systems. They are perfect for applications exposed to severe operating conditions, such as high temperatures, high pressures, and corrosive environments, because of their exceptional strength, toughness, and wear resistance.
Petrochemical Industry: Stainless steel 309H flanges are used in refineries and petrochemical plants exposed to high temperatures and corrosive environments. They provide excellent resistance to high-temperature oxidation and sulfidation.
Aerospace and Aircraft: These flanges are used in aircraft aerospace applications such as exhaust systems, combustion chambers and afterburner components, where high-temperature resistance is critical
Power generation: Stainless steel 309H flanges are used in power plants in applications such as boiler tubes, super heaters, and steam turbines, where they can withstand high temperatures and pressures
Heat Treatment: Stainless steel 309H flanges are used in heat treatment furnaces, where they can withstand high temperatures and heat cycles without losing their mechanical properties.
Chemical applications: These flanges are suitable for chemical applications such as reactors, heat exchangers and vessels where hot chemicals and high temperatures are required
Heat Resistance: 309H stainless steel is designed for high-temperature applications. Make sure the flanges have the proper heat resistance for your operating conditions, considering their maximum temperatures and fluctuations.
End connections: Specify the type of end connections required for your piping system (e.g., butt welded, socket welded, threaded). Make sure the flanges have end connections that match your piping components.
Size and Design: Select the appropriate size and thickness flanges to match your piping layout. Consider nominal pipe size, flange type (e.g., weld neck, slip-on, blind), and flange facing (e.g., raised face, flat face).
Pressure Pressure: Consider the amount of pressure required for your application. Flanges are usually rated based on their pressure class (e.g., Class 150, Class 300). Select flanges with pressure ratings that meet or exceed your system’s maximum pressure conditions.
Corrosion Resistance: Specifies the corrosive conditions in which the flange will be used. Stainless steel 309H provides excellent resistance to oxidation and sulfidation at high temperatures, making it suitable for hot environments. Make sure the flanges have the required corrosion resistance for your application.
