Custom 455 is a precipitation-hardening martensitic stainless steel (Fe-Ni-Cr-Mo-Ti base) used primarily in aerospace applications requiring high strength at elevated temperatures up to 1000°F. The H1000 condition provides peak hardness and strength through aging treatment, delivering ultimate tensile strength around 180–200 ksi with good fatigue and bearing load characteristics, making it suitable for critical rotating components and fasteners in gas turbine engines and launch vehicle structures.
