Applications
Headers, main steam piping and turbine casings, in fossil fuelled power generating plants. Oil refineries and coal liquefaction and gasification plants. Preheat and Interpas temperature 200°C - 300°C.<br>
ES 9018-B92 is designed to weld equivalent ‘type CrMo steel .The Vanadium and Nitrogen improve long term creep properties . These consumables are specifically intended for high integrity structural service at elevated temperature so the minor alloy additions responsible for its creep strength are kept above the minimum considered necessary to ensure satisfactory performance.
