Custom 455 Stainless Steel H1000
VerifiedmetalCustom 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.

Industry-Specific
RoHS, REACH, and Prop 65 statuses are validated against official substance lists (ECHA SVHC Candidate List, OEHHA Prop 65, RoHS Annex II). Other regulations are estimated from composition and material classification. All screening is a starting point for due diligence — always verify with your supplier before making compliance decisions.
