Corrosion Resistance
• NI-SPAN-C alloy 902 is not “stainless”, as it will acquire an adherent red-brown oxide film when exposed to outdoor environments.
Heat Treating
• In order to maintain bright surfaces during final heat treatment the process must be carried out in a high vacuum or in a very pure hydrogen atmosphere.
• An absolute pressure of 0.1 micron or less is required for bright work in vacuum furnaces.
• Pressures around 1.0 micron may produce a faint straw color.
• Ultrapure hydrogen, such as that produced by palladium diffusion cells, will also maintain brightness.
Annealing
• The alloy is carefully processed and ready for heat treatment after fabrication.
• If, for any reason, it is desired to soften the material by annealing, the following instructions should be carefully observed:
• Heat at 1850°F in a reducing atmosphere free from sulfur and quench rapidly.
• Delay in quenching will result in partial hardening of the alloy and subsequent adjustment of the TEC by cold work and heat treatment will be impaired.
• Annealing time is governed by the dimensions of the work.
Welding
• The alloy can be joined by welding, brazing, or soldering if the surfaces to be joined have been thoroughly cleaned.
• The material should be brazed in the heat treated condition in order to prevent cracking.
• Autogeneous inert gas fusion welding has been employed successfully.
• In any joining operation the effect of joining temperature and time must be considered in relation to its effect on the thermoelastic characteristics of the device.
