Cm - Nital Etched Micrography by OMDf - Ferrite and Pearlite
Micrographic detail of a transverse section of the 5 mm thick tubing, in the center of the thickness. Ferritic-pearlitic structure, with the pearlite presenting a coalesced aspect. The tubing was in service at ambient temperature, painted, and the coalesced aspect was generated before service, perhaps during the tubing manufacturing.
