ASTM B564 N04400 Flange, Monel 400 Nickel-Copper Alloy Forged Flange for Corrosion Resistance

Brief Introduction

ASTM B564 N04400 Flange is a high-performance nickel-copper alloy forged flange, strictly manufactured in accordance with ASTM B564 (material standard) and ASME B16.5 (dimensional standard). N04400 (commonly known as Monel 400) is a premium nickel-copper alloy (approximately 65% nickel and 30% copper), renowned for its excellent corrosion resistance to seawater, brine, alkaline solutions, and various organic compounds, as well as good mechanical strength, ductility, and weldability. It is a versatile flange widely used in marine, chemical, and offshore industries, specially designed for medium to high-pressure piping systems that require reliable corrosion resistance and structural stability, serving as a key connection and sealing component in harsh service environments.
