Study on the Influence of Non-Metallic Inclusions on the Pitting Corrosion of API 5L X60 Steel

The most economical way to move liquids and gaseous hydrocarbons is by using pipelines. According several international organizations oil companies, the use of fossil fuels will continue in following decades. For this reason, it important studying different corrosion mechanisms their origins. One that provoke small leaks, affecting pipeline hermeticity, pitting corrosion. It well-known non-metallic inclusion dissolution can trigger pit nucleation. As recognized be random nature, also interesting study nature inclusions present API 5L X60 steel. Probability distributions commonly used describe characteristics are appropriate for characteristics. size plays a key role nucleation because tend generate more defects, especially when these compounds MnS, steel immersed corrosive solution. results research work show there close relationship between inclusions.
