Alloy K500

CMI Alloy Data Sheet 

Description:

Alloy K500 is a nickel-copper alloy, precipitation hardenable through additions of aluminum and titanium. Alloy K500 retains the excellent corrosion resistant characteristics of Alloy 400 and has enhanced strength and hardness after precipitation hardening when compared with Alloy 400. Alloy K500 has approximately three (3) times the yield strength and double the tensile strength when compared with Alloy 400. Alloy K500 can be further strengthened by cold working before the precipitation hardening. Typical application for the alloy which takes advantage of high strength and corrosion resistance are pump shafts, impellers, propeller shafts, valve components for ships and offshore drilling towers, bolting, oil well drill collars and instrumentation components for oil and gas production. It is particularly well suited for centrifugal pumps in the marine industry because of its high strength and low corrosion rates in high-velocity seawater. The alloy is non-magnetic. The alloy should be annealed when welded and the weldment then stress relieved before aging. Corrosion Materials stocks Alloy K500 in a range of sizes including 1/2"-2-1/2" diameter cold drawn, annealed and aged, and 2-3/4"-10" diameter hot finished and aged. Material can be supplied in random lengths, cut to order or machined to your specifications. Machining includes drilling, turning, tapping, threading, CNC shapes, flanges and more.
