Compatibility of Alloys with Hydrazine Containing Freon.

Abstract : The compatibility of hydrazine containing various amounts of Freon 13B1 and Freon TF with 304L and 308 stainless steels that had been joined with Au-Ni braze and Cu braze was investigated in detail. The results are presented in various tables and graphs. It has been found that 304L stainless steel and Au-Ni braze are the most compatible of the combinations of materials, and Freon TF is a more deleterious contaminant in hydrazine than Freon 13B1.
