Stainless steel powder

In terms of its physical and chemical properties, stainless steel powder primarily consists of iron, along with alloying elements such as chromium, nickel, and molybdenum. The chromium content ensures excellent corrosion resistance, nickel enhances toughness and strength, while molybdenum reinforces corrosion resistance and high-temperature performance. Physically, it appears in fine spherical or near-spherical particle shapes, with particle sizes typically ranging from a few micrometers to several tens of micrometers, exhibiting good flowability, which facilitates uniform powder spreading and ensures a smooth printing process with accurate forming. Additionally, it has a relatively high bulk density, meeting printing requirements.
