Description of 18Ni300 steel Powder
18Ni300 Iron Based Metal Powder, also called X3NiCoMoTi 18-9-5, 1.2709 steel, and Maraging Steel 300, is a high-strength steel alloy primarily composed of iron (Fe), nickel (Ni), and additional elements such as cobalt (Co), molybdenum (Mo), and titanium (Ti). The typical composition includes approximately 18% nickel, which gives it its name, along with smaller percentages of cobalt, molybdenum, and titanium that contribute to its remarkable mechanical properties.

18Ni300 steel Powder Reference
- Laser additive manufacturing (LAM) technology has been widely used for manufacturing, strengthening and repairing components in some areas.
- The as-fabricated maraging steel part was composed of amartensitic phase and a small fraction of austenite phase. After heat treatment, the volume fraction of austenite slightly increased because of the long-time heat treatment and the occurrence of the reversion of the martensitic phase into theaustenite phase. The relative density of the as-fabricated part was 98.2% 60.52%.
Maraging alloys are essentially carbon-free, a protective atmosphere is not required during annealing or aging. Material is supplied in the solution annealed condition with a hardness of 30/35 Rc. Typical heat treat time/temperature are listed below. Large cross sections should be aged for longer periods.
The material for additive manufacturing was 18Ni300 maraging steel. This steel is also known as X3NiCoMoTi 18-9-5, an equivalent to 1.2709 steel.
Maraging steel is essentially free of carbon, which distinguishes it from other types of steel. The carbon content is kept very low to avoid the formation of titanium carbide (TiC) precipitates, which severely reduce the impact strength, ductility and toughness when present in high concentration.
