Additional Information
Fabrication
Heavy machining of alloy 500 is best achieved when the material is in the annealed or hot-worked and quenched condition. It is common practice to machine slightly oversize, age-harden, then finish to size. However, age-hardened material can be finish machined to close tolerances and fine finishes. The alloy can be joined by industry-standard welding, brazing and soft soldering processes.
Corrosion Resistance
Alloy 500 provides excellent resistance to corrosion in seawater, oil and gas environments and a wide variety of industrial media. The corrosion resistance of alloy 500 is substantially equivalent to that of alloy 400 (non-hardenable nickel-copper alloy) except that when in the age-hardened condition, alloy 500 has a greater tendency toward stress-corrosion cracking in some media.
