Key features of Stainless Steel 446 Flanges:

High-Temperature Resistance: Stainless Steel 446 is specifically designed to withstand elevated temperatures. These flanges maintain their structural integrity and mechanical properties at temperatures up to 1800°F (982°C), making them ideal for applications such as heat exchangers, furnace components, and exhaust systems.

Corrosion Resistance: Stainless Steel 446 contains a high percentage of chromium, which enhances its resistance to corrosion. This makes it suitable for applications in chemical processing plants and environments where exposure to corrosive substances is common.

Strength and Durability: The combination of chromium and molybdenum in the alloy gives Stainless Steel 446 Flanges excellent mechanical properties. They are known for their strength and durability, ensuring a long service life and reduced maintenance costs.

Weldability: These flanges offer good weldability, which simplifies the installation process and allows for the creation of strong, leak-resistant connections. Proper welding procedures should be followed to maintain the corrosion resistance of the material.

Variety of Flange Types: Stainless Steel 446 Flanges come in various types, including weld neck, slip-on, blind, socket weld, and threaded flanges, among others. This diversity allows them to be used in a wide range of applications and configurations.

Applications of Stainless Steel 446 Flanges:

Petrochemical Industry: These flanges are used in the construction of pipelines and equipment for the transportation and processing of oil and gas.

Power Generation: Stainless Steel 446 Flanges are employed in power plants, particularly in components like high-temperature boiler systems and steam lines.

Chemical Processing: Their corrosion resistance makes them suitable for handling a wide range of chemicals and acids in the chemical industry.

Aerospace and Automotive: In high-temperature exhaust systems and engine components, Stainless Steel 446 Flanges find application in the aerospace and automotive sectors.

Furnace and Heat Exchangers: They are commonly used in the construction of furnaces, heat exchangers, and other equipment that operates at elevated temperatures.

Manufacturing Process Of Stainless Steel 446 Flanges

Raw Material Selection

The manufacturing process of flanges begins with the careful selection of raw materials.

Cutting and Shaping

Once the raw materials are selected, they undergo a precise cutting and shaping process.

Finishings and Coatings

Coating the materials to a specific temperature ensures they become malleable, facilitating the shaping process.

Welding and Joining

These processes ensure secure and leak-proof connections, enhancing the reliability and longevity.

Finishing and Quality Control

After this the buttweld fittings undergo comprehensive finishing and quality control procedures.

Packaging and Delivery

To reach their destination in pristine condition, we employ careful packaging techniques.
