Characteristics and application

MIG/GMAW wire for high temperature, creep resistant, modified 9%Cr-1,7%W-0,5%Mo martensitic steel (T9/P92). T92/P92 steel is commonly used at service temperatures up to 620°C. W,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 T92/P92 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.
