Know about Inconel Flange and its Grades
The Inconel superalloy family, which is based on nickel and chromium, is renowned for its exceptional strength, resistance to corrosion, and capacity to tolerate high temperatures. In industries with demanding operating conditions, inconel flanges are commonly utilized. Here's a thorough rundown:
Properties of Inconel Flanges
High Temperature Resistance: Inconel alloys maintain their strength and integrity at temperatures up to 2200°F (1204°C), making them ideal for high-temperature applications.
Corrosion Resistance: They exhibit excellent resistance to oxidation, corrosion, and pitting in a wide range of environments, including acidic and saline conditions.
High Strength: Inconel alloys are known for their high tensile and yield strength, even at elevated temperatures.
Durability: These flanges are durable and can withstand thermal cycling, mechanical stress, and other harsh conditions without degrading.
Common Grades of Inconel
