What is SS 347 Flanges?

SS 347 Flanges are flange fittings made from stainless steel grade 347, which is a stabilized austenitic stainless steel with the addition of columbium (niobium) and tantalum. These flanges offer excellent high-temperature strength and resistance to intergranular corrosion. SS 347 Flanges are commonly used in applications involving elevated temperatures, such as in thermal processing equipment, exhaust systems, and chemical processing plants.

What is 347 stainless steel flange used for?

347 stainless steel flanges connect pipes or fittings in various industrial applications requiring resistance to high temperatures and corrosive environments. They provide a secure and leak-free connection, allowing for efficient flow of fluids or gases in piping systems. 347 stainless steel flanges are commonly utilized in petrochemical, chemical, and power generation industries, where thermal cycling and exposure to corrosive substances are prevalent.

What is the difference between 304 and 347 stainless steel flanges?

The main difference between 304 and 347 stainless steel flanges is their chemical composition and stability. While both grades are austenitic stainless steels, 347 stainless steel contains columbium and tantalum, which provide stabilization against sensitization and intergranular corrosion at elevated temperatures. This makes 347 stainless steel flanges more suitable for high-temperature applications than 304, which are not specifically designed for such environments.
