MONEL FLANGE

Monel is a trademarked name for a series of nickel-copper alloys known for their strength and resistance to corrosion. The most commonly used grades for Monel flanges are Monel 400 and Monel K-500. Below are the specifications for these grades, including their chemical compositions, mechanical properties, and equivalent standards.1.
