Metrode Chromet-92-25MM description: These consumables are designed to weld equivalent ‘type 92’ P92 9%Cr steels modified with tungsten, vanadium, niobium, nitrogen and a small addition boron to give improved long term creep properties. They 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 practice, 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.
