We publish the mechanical characteristics of 3L stainless steel 316D printed parts after testing.

AISI 316L is a structural cryogenic austenitic steel. This steel is resistant to corrosion in aggressive environments, as well as to most external influences. Steel 316 L tends to maintain the integrity of the structure with increasing and decreasing temperatures.
