316L Stainless Steel Powder

316L Stainless Steel Powder(ss316L) 316L is a stainless steel grade, which is classified according to the metallographic structure and belongs to austenitic stainless steel. The standard grade of the America is AISI316L; the Japanese JIS industrial standard grade is SUS316L; 316L stainless steel has excellent corrosion resistance, especially pitting corrosion resistance, due to the addition of 2~3% Mo element. At the same time, it has good high temperature strength performance and excellent work hardening (weak magnetic properties after processing). 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.
