Overview

Investigation shows microhardness and corrosion resistance in SS309L fabricated by wire arc additive manufacturing, indicating suitability for industrial applications.

Key Points

  • The microstructure of SS309L exhibits heterogeneous phases, highlighting differences due to heat transfer during manufacturing.
  • The average tensile strength of WAAM-fabricated SS309L was slightly lower than that of the feed wire, demonstrating applicability in manufacturing.
  • Fabricated samples showed minimal pitting corrosion, with corrosion rates between 0.01 and 0.023 mm/year, indicating strong corrosion resistance.
  • Insights from this study could optimize wire arc additive manufacturing techniques, enhancing the mechanical performance of stainless steel components.
