Monel K-500
Alloy K500, also called Monel K-500, is an age-harden-able nickel-copper alloy that combines the corrosion resistance properties of alloy 400 with high-strength corrosion fatigue and erosion resistance properties. Alloy K500 is precipitation hard-enable through the additions of aluminum and titanium. The chemical composition of alloy K500 retains the excellent corrosion-resistant characteristics of alloy 400. Compared with alloy 400, alloy K500 has enhanced strength and hardness after precipitation hardening. Alloy K500 has approximately three times the yield strength and double the tensile strength of alloy 400. Alloy K500 can be further strengthened by cold working before the precipitation hardening. Alloy K500 should be annealed when welded and the weldment then stress relieved before aging.
