ASME SB163 / B165 MONEL 400 Nickel Alloy Seamless Tube, Heat Exchanger /Air Cooler Application
ASME SB163 / B165 MONEL 400 Nickel Alloy Seamless Tube, Heat Exchanger /Air Cooler Application
Monel 400 is a nickel-copper alloy renowned for its exceptional corrosion resistance and mechanical strength, particularly in aggressive environments. Alloy 400 is a solid solution alloy that can only be hardened by cold working. This nickel alloy exhibits characteristics like good corrosion resistance, good weldability and high strength. A low corrosion rate in rapidly flowing brackish or seawater combined with excellent resistance to stress-corrosion cracking in most freshwaters, and its resistance to a variety of corrosive conditions led to its wide use in marine applications and other non-oxidizing chloride solutions.Here's a detailed overview:
