Custom 465 is a precipitation-hardened martensitic stainless steel containing cobalt and molybdenum, designed for high-strength aerospace and bearing applications requiring superior fatigue resistance and dimensional stability at elevated temperatures up to ~480°C. The H950 condition (950°F aged) provides ultimate tensile strength exceeding 1700 MPa with good bearing fatigue strength and controlled toughness, suitable for highly-stressed rotating components and precision bearing races per AMS 5936.
