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.
