Obiettivo
The operating temperatures of hydro-processing reactors are at present in the range from 400-480 °C with a corresponding hydrogen partial pressure of 10 to 35 MPa. Currently thick-walled reactors are made of 2.25Cr1Mo or 3Cr1Mo steels. The need for high stress intensity values in order to reduce the reactor wall thickness has been the continuous driving force for the development of alternative higher strength materials such as the addition of V. The aim of the project is the development of a new version of Cr-Mo-V steel with tailored addition of elements to increase the mechanical properties, to maintain the hardness in the welded zone below 250 HV and to reduce the internal protective coating disbonding and the wall thickness.
