Superalloy Fasteners

The MP98T fasteners, manufactured from SPS MP98T superalloy, have a minimum tensile strength of 180 ksi and fracture toughness that exceed 200 ksi in.- 1/2.

This toughness makes them suitable 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. Available in a variety of configurations, the MP98T fasteners come in sizes up to 1.75 in., with larger sizes possible.
