Atmospheric monitoring and gravimetric analysis with low alloy steel (ASTM A36), were done according to ISO 9223 and its associated procedure. There were low values of pollution by chlorides and sulfates, around 5 mg m<span class="char-style-override-2">-2</span> día<span class="char-style-override-2">-1</span> and without important levels of acid rain, despite the proximity of an active volcano, which indicates an atmosphere of “rural type”. TDH’s level was 60 %, initial corrosion speed was 40 μm year<span class="char-style-override-2">-1</span>, and this estabilized after 3 years in 20 µm year<span class="char-style-override-2">-1</span>, with protective oxides. The accumulated corrosion estimated by the model meet ISO Corroag of ISO 9226. The Matlab model produced a best adjustment exponential model with a time dependence factor of 0,89.</p><p class="x06-1-Abstract-y-Key-words" xml:lang="en-US"> </p>}, number={2}, journal={UNED Research Journal}, author={Rodríguez Yáñez, Javier E.}, year={2015}, month={Dec.}, pages={201–207} }
