Maraging 300/Udimar 300/Maraging C300/UNS K93120/UNS K93160 Maraging 300 alloy steels material (also referred to as Maraging C300 and Vascomax C300) 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.

Maraging 300 alloy steel can be welded by conventional methods.

Maraging 300 alloy steel can be forged as for stainless 304 alloy.

Maraging 300 alloy steel has good machinability characteristics.

Maraging 300 alloy steel cannot be heat treated for hardening except by aging.

Maraging 300 alloy steel can be hot worked in temperatures ranging 260 to 93°C (500 to 200°F). Age hardening takes place when this alloy steel is exposed to these temperatures for a long time.

Maraging 300 alloy steel can be hardened by aging and cold working.

Maraging 300 alloy steel has high hardness and strength properties and is thus suitable for an aging heat treatment at 482°C (900°F).
