Description of Stainless Steel 316L Spherical Powder
Stainless steel 316L is a low-carbon version of stainless steel 316, known for its corrosion resistance, especially in environments where exposure to chemicals and saltwater is common.
SS 316L spherical powder, which is advantageous for additive manufacturing processes such as powder bed fusion (like selective laser melting or electron beam melting). Spherical particles flow more easily and evenly during processing, leading to better consistency in the printed parts.

Spherical Stainless Steel 316L Powder Reference
- 316L austenitic stainless steel is one of the most widely used metal materials, which has excellent properties such as high corrosion and oxidation resistance, moderate strength, and good plasticity [28], [29], [30], [31]. So far, many researchers have been devoted to the study of additive manufacturing of 316L SS, especially those about the LPBF technology.
Stainless steel 316 has a maximum carbon content of 0.08%, while stainless steel 316L has a maximum carbon content of 0.03%. The lower carbon content in 316L reduces the risk of sensitization (loss of corrosion resistance in welded areas) and enhances its corrosion resistance in various environments.
Stainless steel powder is suitable for 3D printing because it allows for precise and complex shapes to be produced directly from digital designs using techniques like selective laser melting or electron beam melting. This powder form ensures uniform particle size and flowability, essential for achieving high-quality, durable metal parts with excellent mechanical properties.
Stainless steel powder itself is not flammable under normal conditions. However, like any finely divided metal powder, it can pose a fire hazard if dispersed in air and exposed to an ignition source. The main concern is not the powder igniting spontaneously but rather the potential for combustion if exposed to a strong enough heat source, such as in a fire situation or during certain manufacturing processes.
