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.
Pickling
• Thin oxide films formed by heating the alloy in atmospheres less pure than ultrapure hydrogen or in vacuums lower than those cited can be removed by
mechanical abrasion or by pickling.
• Pickling the final product will result in a decrease in fatigue strength; therefore abrasive blasting or mechanical polishing should be considered for components
which require best fatigue resistance.

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.
