ASTM- B434 UNS N10242 Haynes 242 Nickel Alloy Hastelloy Plate / Strip

Shaped, Flat, Square, Round, Fine Wire, Plated and Un-plated ASTM B434

ALLOY 242® DESCRIPTION

Alloy 242 is a nickel-molybdenum-chromium age hardenable alloy which derives strength from a log-range ordering reaction upon aging. It has tensile and creep strength properties up to 1300°F which are as much as double for solid solution strengthened alloys, but with high ductility in the aged condition. The thermal expansion characteristics of alloy 242 are much lower than those for most other alloys, and it has very good oxidation resistance up to 1500°F.

APPLICATIONS

Seal rings
Containment rings
Fasteners
Chemical processing: such as high temperature HF vapor containing process,
fluoroelastomer processing equipment.

PROPERTIES:TEMPERED

Alloy 242 can be cold rolled to achieve the temper properties required by specific customers and/or manufacturing requirements. Contact Ulbrich Wire for details.

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
