Monel K500/ UNS N05500/ DIN W.Nr. 2.4375 Properties or Features
Monel K500 is a nickel-copper alloy and have a excellent corrosion resistance than Monel 400. And alloy 500 is about three times of the yield strength and double of tensile strength than Monel 400. The Monel K500 is widely used for pump, shafts, oil, well tools and instruments, doctor blades and scapers, spring, valve trims, fasteners, and marine propeller shafts.
Heat Treatment for alloy K500
The annealing is performed both for softening of the matrix after working and for solution of the age-hardening phase. Adequate softening may be achieved with temperatures as low as 760-871℃, but heating at 982℃ for hot finished products and 1038℃ for cold drawn products is recommended for optimum response to subsequent age hardening. Grain growth becomes fairly rapid above 982℃, and if a fine-grained structure is desired heating time should be kept to a min. at these higher temperatures.
