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 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.

F6NM is a stainless soft martensitic Cr steel with 4% nickel with molybdenum addition and medium corrosion resistance in media with only a low chloride content. To achieve the best possible corrosion resistance with F6NM, it is essential to polish the surfaces concerned. Good mechanical properties in the quenched and tempered condition. This makes this material very suitable for use in turbine and power plant construction. Very good low-temperature properties. Recommended temperature of use: – 60 to 350°C. Use for valves, pumps, compressors, centrifuges, hydroelectric machines, turbines, reactor technology, shipbuilding, chemicals. Special heat treatment to max. 23 HRC is required for sour gas environments in petroleum engineering.

ToughMet 3 copper nickel tin alloys (UNS C72900) provide high performance property combinations beyond those found in other alloys. Alloy C72900 resist most sour environments and retain their strength at elevated and sub-zero temperatures. ToughMet alloys are available in different tempers that meet specific application requirements. ToughMet 3 AT110: This is a hot worked and spinodally hardened alloy available in many product forms and sizes. It has good ductility, resilience and low friction. Typical applications include oil and gas hardware including rotary steerable housings, Kelly valve seats, bushings, bearings, threaded components and metal seals. ToughMet TS: This is a cold worked, spinodally hardened alloy designed to provide additional property attributes for the most demanding applications. ToughMet TS95 and TS120U tempers combine high levels of fracture toughness with strength to resist impact loading. ToughMet TS95 temper also provides the highest mechanical wear resistance of the ToughMet alloys. ToughMet TS130, TS150 and TS160U tempers offer the highest strength for the most demanding static structural loads and pressures.
