N05500 Overview

N05500 (or Nickel K500) is a nickel-copper alloy with additions of iron, manganese, aluminium and titanium.

It is resistant to hydrogen sulphide, making the alloy highly suitable for sour gas applications.

Low corrosion rates in seawater also make N05500 (Nickel K500) suitable for use in marine environments, including sub-sea and above-sea applications.
