Application\/properties:<\/strong><\/p>\n\n\n\n

Basic core wire alloyed electrode suited for high temperature martensitic 9%Cr-1%Mo-V-Nb-N  steels, in turbine and boiler fabrication and in the chemical industry especially for T 91 and P91 steels and operating temperatures up to 650 \u00b0C . High creep ruptures strength and good toughness properties under long term stresses.<\/p>\n\n\n\n
