The Monel K-500 nickel alloy has the same corrosion resistance as the Monel 400 but higher mechanical strength and hardness. The strengthened properties are achieved by the additions of aluminum and titanium to the nickel-copper base and by heating under controlled conditions. Monel alloy K-500 also has excellent resistance to high temperature corrosion and long term structure stability. 1.Virtually nonmagnetic, even at quite low temperatures 2.Exceptionally good dimensional stability 3.Resistant to a sour-gas environment 4.Excellent corrosion resistance together with increased strength and hardness of that of Alloy 400
