Stainless steel 347H Flange is typically used in applications where corrosion resistance and strength are important factors. It can be found in many industries, including chemical processing, oil refining, power generation, petrochemical plants, and pharmaceutical manufacturing. Additionally, these types of stainless steel piping components can be found in food processing facilities due to their ability to resist corrosion from acidic substances such as vinegar or tomato sauce. They can also be found in marine environments since they offer superior resistance to saltwater corrosion compared to other metals like aluminum or carbon steel. Lastly, these types of stainless steel piping components can also be found on offshore oil rigs since they offer superior strength at elevated temperatures compared to regular austenitic grades like 304L or 316L. In addition to our range of Stainless Steel 347 Flanges we also offer a variety of Duplex Steel S32205 Flanges to meet your piping needs.

The benefits that come with using stainless steel 347 flange include improved strength at higher temperatures compared with standard austenitic grades such as 304L or 316L. They have non-magnetic properties when cooled below Ferrite transformation temperature (also known as Curie Temperature). SS 347 Flanges have excellent dimensional stability under severe conditions such as vibration etc.and they also have high fatigue strength making it ideal for use in high cycle fatigue applications such as automotive components etc. All these benefits make stainless steel347 flange an ideal choice for many industrial applications where reliability and performance matter most. At Metcore Steel, we pride ourselves on providing excellent customer service and offering a wide range of products, including Stainless Steel 347 Flanges and SS 304 Fasteners.

Stainless Steel 347 Flange is an incredibly versatile material that has numerous advantages over other materials when it comes to piping components due to its superior strength at elevated temperatures along with its excellent properties when exposed to acidic substances such as vinegar or tomato sauce as well as salty environments like marine environments or offshore oil rigs.

Stainless Steel 347 Flanges are available in various styles, such as slip-on flanges, blind flanges, threaded flanges, weld neck flanges, lap joint flanges, and socket weld flanges. Slip-on flanges are the most commonly used type because they are easily installed and provide an economical alternative for connecting pipe sections. Blind flanges are also popular because they can plug off a line or pressure vessel opening without welding it shut. Threaded and lap joint flanges are also often used in applications where quick installation or disassembly is frequently required. Socket weld and weld neck are typically used in high-pressure applications since they require welding for installation, which provides a more robust seal than other types of stainless steel 347 flange connections.


347 stainless steel flanges are commonly used in applications that involve high temperatures, such as chemical processing, power generation, and aerospace. They offer excellent resistance to corrosion, oxidation & high temperatures, making them ideal for use in harsh environments.
SS 347 flanges are pipe fitting made from grade 347 stainless steel. These flanges are designed to provide a strong and reliable connection between two pipe sections or between a pipe and a valve, pump, or other equipment. They are commonly used in high-temperature and high-pressure applications where a strong & reliable connection is essential.
The benefits of using stainless steel 347 flanges include excellent resistance to corrosion, oxidation, and high temperatures. They also offer good weldability and are easy to machine, making them ideal for various applications. They are more resistant to sensitization & intergranular corrosion than other stainless steel grades, which makes them suitable for use in harsh environments where other materials may fail.
