... INTRODUCTION ABSTRACT UNS N04400 and UNS N05500 (in this paper: Alloy 400 and Alloy K-500, respectively) are Ni-Cu alloys that are included in NACE Standard MR0175. Alloy K-500 is the precipitation hardening version of Alloy 400. Both alloys are used in sour service in oil and gas production...

..., about 100 years ago, was a Ni-Cu alloy 400. This alloy is still being widely used in a variety of industries and will continue to be used in this current century. Over the past 100 years, specially in the last 50 years, improvements in alloy metallurgy, melting technology, and thermo-mechanical...

... ABSTRACT Cracking discovered in portions of an atmospheric tower overhead piping system prompted this investigation. Alloy 400 had been used to replace carbon steel that had shown unacceptable metal loss. Intergranular stress corrosion cracking (IGSCC), which was identified as the corrosion...

To reduce seawater valve life cycle costs, passive film-forming alloys are being considered as alternatives to current valve materials (typically bronze and nickel-copper alloy 400). These passive film-forming materials have increased corrosion resistance to most forms of corrosion...
