REPORT ON TEST OF STELLITE #3 GUIDE BUSHINGS WITH H1025 AND H1100 SHAFTS FOR BUFFER SEALS

Tests determine the wearability of two chrome plated 17-4 PH shafts in guide bushing service for buffer seal applications on water reactor control rods. Age hardening specifications in ranges of 1015 - 1035 degrees and 1075 - 1100 degrees made mechanical straightening unnecessary. Each test provided 25,000 feet of travel of a dummy seal shaft with a 3-inch stroke over each wear point. The shaft was supported in two fixed bushings with a 120-pound loaded floating bushing between them. The tests were conducted with water of reactor purity taken from the loop for the buffer seal tests.
