Overview of 18Ni300 Powder

18Ni300 Pulver is a maraging steel powder that offers an optimal balance of styrka, Hårdhet, och duktilitet. It belongs to the class of martensitic age-hardenable steels and exhibits exceptional mechanical properties after the aging process. Its high nickelinnehåll (18%) and low kolinnehåll are responsible for its seghet och maskinbearbetbarhet, while added elements like molybden, kobolt, och titan enhance its overall performance.

This alloy is primarily used in applications that demand hög slitstyrka, dimensionell noggrannhet, och motståndskraft mot deformation. It’s especially popular in additiv tillverkning (3D printing), where its fine powder form allows for precise control over part geometry and properties.

Viktiga egenskaper :

• Hög drag- och sträckgräns after heat treatment.
• Excellent toughness och duktilitet at room and sub-zero temperatures.
• God bearbetbarhet in the annealed condition.
• Resistance to krypa och spänningskorrosion sprickbildning.
• Fine grain structure for enhanced fatigue resistance.
• Low thermal expansion och dimensional stability during heat treatment.
