ISGEC Hitachi Zosen Limited - Case Study

With the rising demand for cost- effective designs of structural components in the oil and gas sector, manufacturers want to utilize the maximum temperature capability of the materials. The current ASME code (Section VIII, Division 2) limits the generation of fatigue curves up to a maximum of 371 °C. 

ASME Code Case 2605 is a special rule used in the industry worldwide for fatigue evaluation of 2.25Cr- 1Mo-0.25V steels at temperatures greater than 371 °C and less than 454 °C.
