Maraging 300
Details
Lork Group high-quality Maraging 300 has exceptional strength, toughness and is resistant to crack propagation. Used for tooling, transmission shafts, autosport components and light aircraft landing gear.
Products Description
Lork Group high-quality Maraging 300 material is a vacuum induction melted and vacuum arc re-melted, low-carbon, nickel-cobalt-molybdenum high-temperature nickel alloy. This material can produce yield strengths in excess of 270 ksi (1862 MPa) through simple, low-temperature heat treatment at 900°F (482°C). Maraging steel 300 also exhibits good ductility at high strength levels, displays excellent notch ductility and outstanding weldability.
Maraging 300 is an age hardenable (maraging) iron nickel stainless steel. Maraging 300 has exceptional strength, toughness and is resistant to crack propagation. Maraging 300 is used for tooling, transmission shafts, autosport components and light aircraft landing gear.
