Spherical Stainless Steel 304L Powder Reference
Spheroidisation of Stainless Steel Powder for Additive Manufacturing
- In additive manufacturing, powder characteristics play an important role in terms of flowability and densification, which can be improved by the use of spherical powders. Spherical AISI 304 stainless steel powders were produced by plasma spheroidization, and the efficiency of the spheroidisation process was evaluated. The spheroidisation process resulted in 93% efficiency with a decrease of fine particles (<63 µm) by 22%, while the all the flowability parameters of the powder improved significantly.
The distinguishing feature of 304L compared to 304 is its lower carbon content (typically 0.03% maximum), which minimizes carbide precipitation during welding and reduces the risk of corrosion in certain environments.
Stainless Steel 304 typically contains about 18% chromium, 8% nickel, and ≤0.08% carbon, while Stainless Steel 316 includes roughly 16-18% chromium, 10-14% nickel, and 2-3% molybdenum, enhancing its corrosion resistance properties, especially in harsh environments.
The choice between Stainless Steel 304 and 316 depends on the specific application and environmental conditions:
Stainless Steel 304:
Advantages: Good general corrosion resistance, particularly in less aggressive environments such as rural atmospheres, food processing facilities, and indoor applications.
Disadvantages: Less resistant to chloride environments and may corrode over time in marine or coastal environments.
Stainless Steel 316:
Advantages: Higher corrosion resistance, especially against chlorides and acids. It is suitable for marine environments, coastal areas, and applications involving exposure to chemicals or saltwater.
Disadvantages: Generally more expensive than 304 due to the addition of molybdenum.
Decision Factors:
Choose 316 for superior resistance in aggressive environments.
304 is typically more cost-effective unless the enhanced corrosion resistance of 316 is necessary.
