Alloy: Fe/ Ni / Cr
Wire feedstock: AM 316LSi; 3Dprint AM 316L
AISI 316 belongs to the austenitic stainless steel class. The addition of the alloying elements brings high corrosion resistance by the formation of a protective oxide layer on the material surface, with good ductility and thoughness. AISI 316L has lower C content, which improves the resistance to intergranular corrosion. These alloys are widely used in the chemical sector, food and process industry and maritime applications.
The mentioned mechanical properties can vary according to design changes, process parameters optimization and strategy selection.

Straight lines strategy: several welding beads overlapped next to each other
Oscillation: continuous zig-zag bead that fills the entire layer
Stress relief: due to the high residual stresses build up in the WAAM product, this heat treatment is necessary to minize residual stresses.
