Haynes 188 is a cobalt-based alloy which possesses a unique combination of properties. It has excellent high temperature strength and oxidation resistance to 2100°F (1150°C) combined with good post-aging ductility.
Alloy 188 has average room temperature tensile properties in the bright annealed condition of 137.2 ksi (946 MPa) ultimate strength, 67.3 ksi (464 MPa) yield strength and 53% elongation. At 1800°F (980°C) the alloy has ultimate and yield strengths of 35.2 ksi (243 MPa) and 19.0 ksi (131 MPa), respectively, with 59% elongation. Cryogenic temperatures do not significantly affect the ductility of alloy 188, but strength levels are increased markedly.
The excellent oxidation resistance of Haynes 188 results from minute additions of lanthanum, which modifies the protective oxide scale in such a manner that the oxide becomes extremely tenacious and retards diffusion when exposed to temperatures through 2100°F (1150°C).
Haynes 188 exhibits good ductility after prolonged exposure at temperatures of 1200, 1400, and 1600°F (650, 760 and 870°C) for 16,000 hours.
The chemical composition of Haynes 188 is outlined in the following table.
Waspaloy (also known as Alloy 685) is a nickel base, age hardenable superalloy with excellent high-temperature strength and good corrosion resistance by combustion products, notably to oxidation, at service temperatures of up to 1200°F (650°C) for critical rotating applications, and up to 1600°F (870°C) for less demanding applications. At temperatures over 1600°F (870°C), intergranular oxidation can occur. The corrosion resistance is very good even after numerous cycles of elevated temperature exposure, or constant exposure to temperatures of up to 1900°F (1038°C). For the best possible corrosion resistance, solution-treated material is recommended. Waspaloy is also known to behave well in atmospheres in gas turbine engine service and salt spray environments. Due to these properties, Nickel Waspaloy finds use in gas turbine engine components and aircraft jet engines, such as compressor disks, rotor disks, shafts, spacers, seals, rings, and casings. It also finds use in fasteners and other engine hardware in airframe assemblies and missile systems. Waspaloy is produced by vacuum induction melting and vacuum arc refining (VIM/VAR), or by vacuum induction melting and electroslag refining (VIM/ESR). Tech Steel & Materials offers Nickel Waspaloy in 8 sub-type specifications and in multiple shapes/forms:
Chemical Composition of Nickel Waspaloy
*Not exclusively to the element mentioned, but that one predominates other elements that are used only in minimal quantities. Fabrication and Working Instructions for WaspaloyWaspaloy can be hot-worked in the temperature range of 2140-1800°F (1170-980°C), and cold-worked by hydroforming, drawing, spinning, bending, and rolling. That said, this nickel base alloy is difficult to machine and special instructions must be followed. As for joining, Waspaloy can be readily-welded only in carefully controlled circumstances with argon-arc methods using the AMS 5828 composition filler metal. That said, welds should be avoided in high-stress locations, due to the fact that the high strength of the welds is lower than a heat-treated material. More precisely, Waspaloy may show "hot short" tendency and sensitivity to strain cracking. That's why, it is highly recommended that welding is done on a material that is only solution treated, and then re-solution treated together with the weld.

Nickel Waspaloy is heat treated in a three-step sequence. There are two different treatments available, both giving different properties to the alloy:
For parts that require high-temperature creep and stress-rupture properties:
For parts that require optimum tensile properties at room temperature and high-temperature environments:
Scale may be formed on the alloy during heat treatment in oxidizing atmospheres. However, this doesn't affect the properties of the alloy and can be removed by acid pickling or mechanically.
