AI Thread Summary
The image of 1018 steel at 100x zoom reveals darker regions identified as perlite. 1018 steel typically contains 0.15-0.20% carbon, with the specific carbon content being 0.18%. The annealing treatment leads to a microstructure comprising both perlite and ferrite. In the micrograph, the dark areas represent perlite, while the bright regions indicate ferrite. This analysis confirms the expected microstructural characteristics of annealed 1018 steel.

Hi, steel 1018 usually has between 0.15-0.20 % of Carbone, yes, the darker regions are perlite

Sure, dark structure is Perlite.
Carbon fraction is given in alloy specification

1018 \rightarrow 0.18% Carbon

And ... Annealing Treatment ( Total Annealing) may result in perlite + ferrite.
It's shown in your micrograph
Dark - perlite
Bright - Ferrite
