Introduction: What is 18Ni300 Powder and Why It Matters in Industry
18Ni300 powder, also known as maraging steel 300 or 18% nickel maraging steel, is a high-strength, low-carbon iron-nickel alloy known for its excellent mechanical properties and superior toughness. It is primarily used in additive manufacturing (AM), metal injection molding (MIM), and powder metallurgy (PM) processes.
For B2B professionals—especially those in aerospace, tool & die, and automotive sectors—18Ni300 powder offers critical advantages like:
- Exceptional Yield Strength: After aging, it can reach up to 2000 MPa.
- Good Weldability: Ideal for additive manufacturing, especially laser powder bed fusion (LPBF).
- Dimensional Stability: Maintains structure during aging and machining.
- Reusability: High recyclability in 3D printing processes.
With the rapid adoption of metal 3D printing in industrial-scale manufacturing, the demand for high-quality 18Ni300 powder has surged among wholesale buyers, OEMs, and AM service providers.
