Superalloy fastener

• strong, tough

• corrosion resistant

This company now offers fasteners manufactured from MP98T superalloy. The new fasteners offer a minimum tensile strength of 180 ksi, and typical fracture values tested per ASTM E1820 exceed 200 ksi/in2. The alloy also resists embrittlement in high-pressure hydrogen environments such as found in rocket motors using liquid hydrogen fuel. Bolts made from this superalloy are available in various configurations and have been produced in sizes up to 1.75-in., with customized larger sizes possible. Maximum operating temperature is 850°F. The new alloy was developed by modifying the company’s MP159T alloy by using the same chemistry but different cold work and age hardening parameters. The tensile strength was reduced from 260 ksi to meet desired high fracture toughness requirements. SPS Technologies Inc, Jenkintown, PA. www.rsleads.com/306df-105
