Pit corrosion of 316L chemical pipeline was studied about microstructural phenomena of grain boundary, twin boundary and metal flow. All the initiation of pits usually was occurred at grain and/or twin boundaries as like wedge type crack. On the other hand, surface pores might be occurred along metal flow of the typical microstructure of extruded 316L pipeline, which be progressed into inside of the pipeline with step by step. Pit holes were formed into both of grain boundary & metal flow line corroded surface. And all the pit deposits were composed of Al & Cl accumulation, which were also the chemical composition.

The microstructural changes of three pieces from an ancient iron pot were studied in order to identify present the material degradation due to repeated heating for one-thousand years. The microstructures of the pieces were divided into the areas of ferrite/graphite, ferrite/pearlite, and corroded oxidation. The area of ferrite/graphite was undergone by severe Galvanic corrosion, but that of ferrite/pearlite was not even during a thousand years` using . The shape of the graphites was coexisted with types of A, B, and C of as modern graphite classification. In the ferrite/pearlite area, abnormal acicula precipitates with a high aspect ratio of 0.2㎛thickness and several hundreds ㎛length were presented. They might be a kind of carbide in the ferrite matrix with its special precipitate plane.
