Stainless Steel 347 Blind Flanges

Stainless Steel 347 Blind Flanges have a unique chemical composition that includes Chromium, Nickel, Columbium + Tantalum, Molybdenum, Iron, and Nitrogen. The alloy provides excellent corrosion resistance thanks to the oxidation protection from Chromium, and increased strength from Nickel and Columbium + Tantalum provides further hardening over time. Additionally, Molybdenum allows for reliable welding between the flange and pipe, while Iron adds toughness to the alloy even at low temperatures. Finally, Nitrogen adds increased strength and corrosion resistance making them highly durable for extended use in a variety of applications.

SS 347 Blind Flanges are commonly used in petrochemical processing, cryogenic storage tanks, and heat exchangers. Their unique chemical composition imparts exceptional resistance to corrosion and pitting, making them ideal for these applications. Additionally, their strength and toughness make them highly durable even at low temperatures. Furthermore, their ability to be welded securely makes them the perfect choice for these demanding environments.
