Annealing reduces tensile strength and yield strength while enhancing elongation in laser powder bed fusion 316L stainless steel, leaving property anisotropy largely unchanged.
Annealing at temperatures of 923 to 1273 K for 2 h eliminates the cellular network within grains, which increases tensile elongation but accelerates localized corrosion.
Microstructural analysis shows that thermal processing triggers grain boundary precipitation without phase changes, highlighting that standard heat treatment is largely unnecessary.
