UNIMAR 250 is a maraging alloy steel having high strength, good notch toughness, excellent cryogenic properties and deep hardenability. It is recommended for pressure vessels, solid-fuel rocket cases and pressure bottles, landing-gear components, processing equipment operating in the temperature range of 300 to 600 F, and components for spacecraft, jet engines and gas turbines. This datasheet provides information on composition, physical properties, hardness, elasticity, and tensile properties as well as fracture toughness and fatigue. It also includes information on high temperature performance and corrosion resistance as well as forming, heat treating, machining, and joining. Filing Code: SA-304. Producer or source: Cyclops Corporation.
