The Maraging 250/300/350 Sheets and Plates are primarily made of iron and nickel (18–25%), with some cobalt, molybdenum, and titanium thrown in for good measure. After heat treatment, these alloys develop a tough martensitic structure that provides impressive strength and ductility. The different grades of Maraging 250/300/350 vary in tensile strength, ranging from 250 ksi to 350 ksi, while still offering excellent fracture toughness and dimensional stability. They boast superior fatigue resistance, minimal distortion during aging, and good machinability. This remarkable blend of strength, hardness, and toughness makes them perfect for critical applications that require extreme performance and durability.
