Monel® 400 or Alloy 400 Description Wire Description


Alloy 400 is a ductile material and with combination of nickel and copper is resistant to a wide variety of corrosive conditions. This alloy is most frequently applied in a range of environments going from mildly oxidizing through neutral and to moderately reducing conditions. Additional application area of this material is in marine environments and other non-oxidizing chloride solutions.

Applications


Cable wrap for oil and gas production
Marine components
Chemical processing
Fasteners
Screens

Additional Properties


Corrosion Resistance


Refer to NACE (National Association of Corrosion Engineers) for recommendations.

Standard Wire Finishes


Extra Clean: (XC) Extra clean is also referred to as “bright annealed” or “bright annealed and cold rolled”
Grease (round wire only): Drawn in a heavy grease produces an “Ultra bright” finish for decorative applications

Soap (round wire only): Soap is used as a lubricant in the drawing process and is not removed. It acts as a lubricant during customer part forming operation.

A soap finish is available in tempered products.
Plated: Many plating options are available.
*Special finishes are available: Contact Ulbrich Wire Sales with special finish and plating requests.

Forms


Continuous Coils
Cut to lengths
Precision cutting

Heat Treatment


Alloy 400 is non hardenable by heat treatment.
