SPS Technologies Offers Fasteners Manufactured from MP98T Superalloy

January 06, 2006

JENKINTOWN, PA . - SPS Technologies, a leading manufacturer of high-strength fasteners and precision components since 1903, now offers fasteners manufactured from the recently-developed SPS MP98T™ superalloy, which exhibits a combination of strength, toughness and corrosion resistance not previously available in a fastener material.

MP98T fasteners offer users a minimum tensile strength of 180 ksi. Typical fracture toughness values on MP98T specimens tested per ASTM E1820 exceed 200 ksi ● in -1/2. MP98T fasteners' strength level and unprecedented fracture toughness make them ideal for critical aerospace engine and airframe applications. The alloy also resists embrittlement in high-pressure hydrogen environments, such as rocket motors using liquid hydrogen for fuel.

MP98T bolts are available in a variety of configurations. Sizes up to 1.750-in. have been produced to date, but larger sizes are possible. MP98T nuts have also been manufactured.

SPS Technologies supplies high-strength fasteners for commercial and military aircraft, jet engines, high performance piston engines and other applications requiring reliability and consistent quality. SPS Technologies product engineers, supported by an experienced technical staff, are available to assist in product design and material selection.
