“…This type of stainless steel is used in medical devices such as implants [13]. Moreover, the high corrosion resistance of SS 316L provides by a thin chromium oxide film that has high stability against corrosion [14,15]. However, this SS 316L material still has some shortcomings; for example, when SS 316L is used as one of the materials for shipbuilding.…”

Stainless steel is one of the materials with excellent corrosion resistance, so it is widely applied in various fields such as the chemical industry, aerospace, power generation, and biomedicine. The environmental condition (neutral, acidic, salty, or basic) is the most important thing to be considered prior to choosing palpable stainless steel materials. In this study, the corrosion behaviors of stainless-steel type SS 316L under exposure immersions in salty and acidic environments using sodium chloride (NaCl) and sulfuric acid (H2SO4) solutions were investigated, by referring to a standard method of ASTM G31-72. Scanning electron microscopy (SEM) results revealed that the specimen in NaCl solution exhibited a darker color, and relatively similar shape of cracks are observed. In contrast, the specimen immersed in H2SO4 was observed to have a large diagonal crack. The corrosion rate of SS 316L immersed in NaCl was lower with a value of 0.4260 mpy, compared to that of H2SO4 which was 2.5141 mpy. The Vickers hardness test showed that the hardness value of NaCl immersion was higher than that of H2SO4, which was 6.34% and 1.94%, respectively. It can be concluded that the SS 316L is better used in a salty environment compared to acidic conditions, because the main function of SS 316L is to be able to withstand rust, one of which is caused by chloride compared to other types of stainless-steel.

Predicting fatigue life of a given specimen using analytical methods can sometimes be challenging. An approach worth considering for this prediction involves employing fracture mechanics. Fracture mechanics can complement both laboratory experiments and finite element analysis (FEA) in estimating fatigue life of a given specimen, if relevant. In the case of aluminum light poles containing a welded hand-hole, the fatigue life has not yet been thoroughly predicted. The University of Akron has conducted a comprehensive fatigue study on aluminum light poles through various means, albeit without of predicting of said fatigue life of the specimens. AFGROW (Air Force Growth) can be used as a fracture mechanics software to predict fatigue life. ABAQUS was used (for FEA) in conjunction with the AFGROW analysis. The purpose of this study was to ultimately predict the life of the specimens tested in the lab and was achieved with various models including hollow tube and plate models. The plate model process was ultimately found to be the best method for this prediction, yielding results that mimicked the data from the laboratory. Further application for this form of fracture mechanics analysis is still yet to be determined, but for the sake of aluminum light poles, it is possible to predict the fatigue life and utilize said prediction in the field.
