Super alloys or high performance alloys include iron-based, cobalt-based and nickel-based alloys. These alloys contain good oxidation and creep resistance and are available in different shapes.
Super alloys can be strengthened by precipitation hardening, solid-solution hardening and work hardening methods. These alloys can function under high mechanical stress and high temperatures and also in places that require high surface stability.

Fabrication and Heat Treatment
Glass sealing 42-6™ can be annealed at 788°C (1450°F) and then cooled in air.
Glass sealing 42-6™ is capable of being readily cold worked due to good ductility of the alloy.
Conventional procedures are used for welding Glass sealing 42-6™.
Glass sealing 42-6™ can be forged at 1204°C (2200°F). During the forging process, this alloy should be prevented from being contaminated by sulfur as a result of prolonged soaking in a furnace atmosphere.
Glass sealing 42-6™ contains good formability characteristic as it has ductility.
Conventional methods can be used to readily machine Glass sealing 42-6™.
Glass sealing 42-6™ can be hardened only when cold worked.
Glass sealing 42-6™ is suitable for annealing teat treatment as it cannot be hardened by heat treatment.
Glass sealing 42-6™ is suitable for use in glass sealing of double pane windows and cathode ray tubes.
