Alloy 46 UNS K94600 bar / sheet/ strip

Product Detail

Common Trade Names: Alloy 46, 4J46, Fe-46Ni, UNS K94600, NiLo46

Alloy 46 is obtained at a given termperature range by adjusting the content of nickel internal energy and the expansion coefficient of different softglass and ceramic matching a series of expansion alloy, its expansion coefficient and the Curie temperature increases with the increase of nickel content.The assembly is widely used in electric vacuum industry the sealing structure ofthe material.

Grade	Heat treatment of samples	20～300°C	20～400°C	20～500°C
Alloy 46	Heat to 850～900°C in a protective atmosphere or in vacuum condition, hold for 1 hour, and then cool to 300℃ at a rate less than 300℃/h	5.5～6.5	5.6～6.6	7.0～8.0

Notes:
1. The Vickers hardness of the annealed strip (sheet) should be no more than 170.
2. For the unannealed strip (sheet) delivered, after heat treat at 900℃, and then hold for 30 min, the Vickers hardness should be no more than 170.
