Special nickel alloy Monel K500 UNS N05500 2.4375 hex bolt DIN933 ISO4017

Monel K500 (alloy K500), UNS N05500 (QQ-N-286), is a precipitation-hardenable nickel-copper alloy that combines the corrosion resistance of Monel alloy 400 with greater strength (over 2x as strong) and hardness. It also has low permeability and is nonmagnetic to temperatures as low as -150¡ãF (-101¡ãC).

Also known as alloy K500, Monel K500 bolts are comprised of a nickel alloy that combines the outstanding corrosion resistance of Monel 400 with increased strength and hardness. These additional attributes of Monel K500 bolts are a result of an age hardening process where aluminum and titanium are added to the nickel-copper base and then precipitated throughout the matrix. This process gives K500 approximately 3 times the yield strength ( 110ksi vs 45ksi) and double the tensile strength (160ksi vs 83ksi) when compared 400. Monel K500 bolts will retain their strength to 1200¡ãF and even retain their ductility as low as -400¡ãF.
