Stress Corrosion of Chaparral Fin Retainers
Abstract
An investigation of the stress-corrosion characteristics of two materials proposed for use as fin retainers for the CHAPARRAL missile system was made. The two materials were 17-7PH stainless steel and QQ-S-777 carbon spring steel. Retainers made from these two materials were mounted on a test fixture, which simulated the static loading conditions, and subjected to a salt fog environment per MIL-STD-151-B. It was concluded that the retainers manufactured from the spring steel (QQ-S-777) were superior to those manufactured from the 17-7PH stainless steel.
