Abstract

The behavior microestructural of the super alloys hastelloy C-276 is analyzed, the one which for its resistance characteristic to the corrosion, it is used in a fluid that presents different concentration elements, besides the speed of the same one for its transport. He was carried out the sample analysis without being exposed to work conditions and after retreat of service. It was determined that the most remarkable effects that affect their operation are the phenomenon of the corrosion for stings and the inter granular, associated to the impoverishment of the chromium layer in the affected areas. When establishing the profiles of hardness, this property falls in the measure that meets the super alloys in contact with the fluid.
