SMAW Stick electrodes
Basic, Cr and Mo-alloyed electrode for heat resistant steels T/P92.
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.
9018-B9 (P92) is designed to weld equivalent ‘type T/P92 CrMo steels modified with 1,6% Tungsten to match the basemetal 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. In this case, weldments will be weakest in the softened (intercritical) HAZ region of parent material, as indicated by so-called ‘type IV’ failure in transverse weld creep tests.
