    1.Introduction

    4J28 is glass-to-metal sealing and iron-chromium alloy. Nominally 28 % chromium, in strip, bar, wire, and

    rod forms intended primarily for sealing to glass in electronic applications. UNS K92801 should only be

    considered for use at service temperatures below 300°C. The alloy is prone to sigma phase formation at

    temperatures close to 620°C, and exhibits brittle mechanical behavior after prolonged exposures at

    temperatures close to 475°C.


    2.Chemistry composition (%)

    Some chemical properties of permalloy 4J28 include:

    CPSMnSiNiNCrFe
    0.120.020.0210.70.50.227.0~29.0Balance

    Notes:

    1.Under condition that the average coefficient of the linear expansion meets the requirements of the

    standard, the content of chromium is allowed to deviate from the stated range.

    2.The shape and dimensions of the alloys are in compliance with GB/T14985.


    3. Typical properties

    Note:

    The hardness of the annealed strip should be no more than 170. Hardness inspection is not required

    when the thickness of the strip is less than 0.2mm.
