voestalpine Specialty Metals offers many different conditions of creep resistant 718 Nickel Alloys, commonly referred to as Inconel Alloy 718. AMS 5662 solution treated and AMS 5663 solution treated and aged, as well as many other customer specific conditions. AMS 5662 is the rawest state of 718, and the softest condition of the AMS group. It can be heat treated to AMS 5663. This heat treatment can be done in two ways to achieve specific outcomes such as optimum impact properties, or optimum tensile and creep-rupture properties. The hardness of AMS 5662 is Max 28HRC in the annealed condition and can increase upon aging to about 36-43 HRC.

Alloy 718 (UNS N07718) is a high-strength, corrosion-resistant nickel chromium material that offers high strength and excellent corrosion resistance, particularly in H2S and CO2 environments.  For applications requiring higher yield strength, consider our BOHLER L718 API-150ksi, which offers a minimum yield strength of 150 ksi. 718 can be used in high temperatures as it has high temp de-rating factors and maintains strength at elevated temperatures.  Several conditions of 718 API are available at vSM. We offer the NACE/API 6ACRA versions at 120 ksi min yield as well as the 150 ksi high strength version.  Both tempers are suitable for sour service and can be used for pressure containing and pressure controlling equipment in corrosive environments. Typical applications include packers, safety valves, pumps, hangers, connectors, and fasteners.

Alloy 925 (UNS N09925), commonly known as Incoloy 925, is an age-hardenable nickel-iron-chromium alloy with additions of molybdenum, copper, titanium and aluminum. Alloy 925 is used in numerous applications requiring a combination of high strength and corrosion resistance.  For applications requiring higher strength, explore our Alloy 725, which offers superior mechanical properties and corrosion resistance. The nickel, in conjunction with molybdenum and copper, provides excellent resistance to reducing chemicals and its chromium content renders protection in oxidizing environments.  Because of its resistance to sulfide stress cracking and stress-corrosion cracking in sour crude oil and natural gas, it is used for down-hole and surface gas well components including but not limited to: packers, pump shafts in marine environments, safety valves, hangers, landing nipples and fasteners.
