316L stainless steel powder is a common metal powder with excellent properties and broad application prospects. It belongs to the austenitic stainless steel series and is a low carbon, low silicon, high nickel, and high molybdenum alloy powder. At room temperature, 316L stainless steel powder has excellent corrosion resistance and good processing performance, making it widely used in various fields.
1. Preparation of 316L stainless steel powder
There are two main methods for preparing 316L stainless steel powder: water atomization and gas atomization. The water atomization method is to pour molten metal liquid into the center of a high-speed rotating disk, forming a thin film, and then use high-pressure water to wash the metal liquid film into small particles. The atomization method is to spray molten metal liquid into a high-speed airflow through a nozzle, which results in the metal liquid's granulation. The advantages of the atomization method are high production efficiency, small particles, and smooth surface, making it suitable for preparing high value-added 316L stainless steel powder.
2. Performance characteristics of 316L stainless steel powder
