General characteristics
9%Cr-1%Mo consumables with small additions of Nb, V and N, designed to weld equivalent type 91 for high integrity structural service at elevated temperature, especially in power generation plants and oil refineries
niobium (columbium) and vanadium allow to provide strength, toughness, fatigue life, oxidation resistance and corrosion resistance at elevated temperatures. Thermal treatment of this alloy is critical and must be closely controlled. The temperature Mf at which the microstructure has complete transformation into martensite is relatively low; therefore, upon completion of welding and before post weld heat treatment, it is recommended to allow the weldment to cool to at least 200°F [93°C] to maximize transformation to martensite.
