Profile

This page is mainly introduced the Alloy 52 chemical information,mechanical properties, physical properties, mechanical properties, heat treatment, and Micro structure, etc. It also contains the use of Alloy 52,such as it is commonly used in bars, sheet,plates, steel coils, steel pipes,forged and other materials application.
ALLOY 52, UNS N14052

STRIP, FOIL & WIRE, ASTM F30

Applications

Applications for Alloy 52 include magnetic reed switches and seals that need controlled linear expansion to approximately 977°F (525 °C)

Description

Alloy 52 is a 50.50% nickel-iron alloy developed for glass-to-metal seals for some of the soft glasses and some ceramics. The alloy’s rate of thermal expansion is virtually constant to a temperature of about 1050°F (565°C).

Finishes
#1 – Hot rolled annealed and descaled. It is available in strip, foil and ribbon. It is used for applications where a smooth decorative finish is not required. # 2D – Dull finish produced by cold rolling, annealing and descaling. Used for deep drawn parts and those parts that need to retain lubricants in the forming process. # 2B –Smooth finish produced by cold rolling, annealing and descaling. A light cold rolling pass is added after anneal with polished rolls giving it a brighter finish than 2D. #BA Bright annealed cold rolled and bright annealed #CBA Course bright annealed cold rolled matte finish and bright anneal #2 Cold Rolled # 2BA – Smooth finish produced by cold rolling and bright annealing. A light pass using highly polished rolls produces a glossy finish. A 2BA finish may be used for lightly formed applications where a glossy finish is desired in the formed part. Polished – Various grit finish for specific polish finished requirements
* Not All Finishes are Available for All Alloys – Consult Sales for Applicable Finishes
Wire Finishes
XC-Extra clean. Bright annealed or bright annealed and cold rolled
Grease-Ultra bright finish for decorative applications
Soap-Soap is not removed from tempered wire to act as a lubricant.
* Contact Ulbrich Wire with special finish requests.
Heat Treatment Alloy 52 is non hardenable by heat treatment.
Welding For best results refer to: SSINA’s “Welding of Stainless Steels and Other Joining Methods”.
