Abstract


Corrosion is one of the issues that concerns today because it can lead to destruction of metal. Low steel carbon is one of
metal types that has been widely used in industry, such as motorcycle component (fuel tank), and fuel shelter. However,
low carbon steel use is highly suceptible to corrosion. The corrosion of motorcycle components (fuel tank) can decrease
strength, tank life, that will harm the safety of motorists. In addition, corrosion in fuel shelters (premium and pertalite)
can result in leakage of the container. The leakage is very vulnerable to fire. This research aims to analize corrosion rate
of low carbon steel speciments that immerse in fuels, premium and pertalite. Method of research includes preparation,
cutting and weighing of specimens before immersing the specimen in the fuel. Every 30 days the specimens were
removed from the fuel then cleaned from the impurities and re-weighed. Weight loss wass used in calculating the
corrosion rate occurring in the speciments. The result show that pertalite and premium corrode the speciments, low
carbon steel. Corrosion rate of speciments immersed for 30 days in premium was faster than in pertalite. The speciments
immersed in premium experienced with weight reduction from 14.312 gram to 14.307 gram, 0.05 mm/year of corrosion
rate. Meanwhile rate of corrosion of the speciments immersed in pertalite was 0.005 mm/year by which reduced the
weight from14.312 gram to 14.307 gram.
