Characteristics and application
Submerged arc welding wire for high temperature, creep resisting, modified 9%Cr-1%Mo martensitic steels (T91/P91). T91/P91 steel is commonly used at service temperatures up to 620°C and the UP-P91 wire has approval for long term service up to 650°C. V, Nb and N additions provide this ‘creep strength enhanced ferritic’ (CSEF) alloy with improved high temperature creep resistance compared to standard CrMo creep resistant alloys. Alloy T91/P91 is widely used in the power generating industry for fossil fuel ultra-super-critical (USC) power plant boilers and turbines; the alloy is also finding applications in the chemical and oil and gas industries.
Base materials
For matching P91, 9%Cr-1%Mo modified, creep resisting martensitic steels.
