ASTM B564 Inconel 601 Flanges
What is Inconel 601 Flanges
Inconel 601 Flanges are considered to be the most ductile and durable flanges in the metal industries. Inconel 601 flanges are also known as heavily alloyed flanges. These flanges are enriched with excellent properties and characteristics. Inconel 601 flanges have amazing mechanical and chemical properties which is also a stand out feature of these flanges.
Inconel 601 grade is made with a mixture of nickel and chromium with a small amount of aluminum. The addition of aluminum and other elements provides excellent protection from all types of chemical reactions. It also protects an alloy from rusting and erosion. Inconel 601 flanges are commonly used in machines and plumps for various purposes.

Inconel 601 Slip On Flange, DIN 2.4851 Reducing Flanges, UNS N06601 Loose Flanges, 601 Inconel Spades Ring Spacers Flanges, DIN 2.4851 Ring Type Joint Flanges, ASTM B564 Inconel 600 Spectacle Blind Flanges Exporter.
Inconel 601 Flanges protect itself from acid attacks and chemical reactions. It also provides excellent resistance to the grade. Inconel 601 flanges provide excellent resistance from corrosion, crevice corrosion and stress cracking. Inconel 601 flanges are probably cooled at the temperature 1000°F to 1400°F. Inconel 601 flanges provide outstanding thermal conductivity and heat resistance.
Inconel 601 flanges are commonly used for joining two or more pumps, valves and pipe ends together. These flanges are used as permanent/ temporary joints. These flanges are obtainable in various sizes and shapes.
