Additive manufacturing (AM), also known as 3D printing. 3D printing technology is a kind of rapid prototyping technology. Many different metals and metal alloys are used in additive manufacturing.
By using metal powders, it prints and constructs objects layer by layer based on digital model files. In recent years, with the rapid development of 3D printing equipment, 3D printing has been widely used in the industrial fields, such as model and mold manufacturing, automobile, aerospace, dentistry and medical treatment education.
304L stainless steel powder is one of the most used material for 3D printing.Stainless Steel Powder 304L is a kind of common stainless steel, it is widely used to make for a good comprehensive performance, corrosion resistance and formability of equipment and parts. Nitrogen Atomization Spherical Stainless Steel Powder has the characteristics of low impurity content，high sphericity（good fluidity of interval powder), no chemical segregation and stable performance.

Pulverizing process:
1. Matching, we need to match the alloy according to the proportion.
2. Melting, put the prepared metal alloy in a high temperature for melting and smelting, so that the metal powder becomes a flowing liquefied body.
3. After high temperature, the alloy is deoxidized, slag-forming, slag-removing, and slag-removing treatment, and finally added to the alloy product.
4. After cooling and grinding, the product is filtered and cooled, and then the alloy block metal is pulverized. The pulverized powder particles are sent to the cyclone separation or rotating drum by wind force, and the ventilation reaches a certain level. The product is collected, and finally sieved and packaged into a product. By filtering out residual materials or substances with excessively large particles, qualified products are packaged for processing.
Application
(1) 3D Printing
(2) injection molding(MIM)
(3) powder metallurgy(PM)
(4) spraying coating(SP) etc.
