    Rationale

    Vallourec has developed a modified 9Cr steel. A user has requested to include this new material into the ASME BPVC as a Code Case and subsequently also into ASTM A213/A213M and ASTM A335/A335M. The material is fulfilling the needed requirements of improved coking resistance and high creep strength better or equal than the well established Grade 9. The modified 9Cr steel has been developed, tested and evaluated over a long time and Vallourec will separately supply supporting data. The modified 9Cr steel has already been included in the German VdTV Material Datasheets No. 588, which means it is ready for use under the European Pressure Equipment Directive with a particular Material Appraisal. The steel is considered worldwide as a candidate construction material for refinery applications.
