    KX 4J40 Corrosion Resistant Alloy Light Rod On Expansion Alloy


    Product Description and Application

    4J40 is also known as Alloy 40

    4J40 is Fe-Ni-Co ternary alloy and its curie point is above 300℃. The alloy has a low expansion coefficient in the temperature range of -20 ~ 300℃, and the transformation from austenite (γ) to martensite (M) does not occur until -60℃. The alloy is mainly used in the manufacture of highly precise instrument parts and electronic devices requiring sizes in the temperature range of -50 to 300℃
