(pipe) The Welding & Filler Metal for T91/ P91 Steel

The Welding & Filler Metal for T91/ P91 Steel. T91/ P91 steel manufactured to ASTM A335 P91 or ASTM A213 T91 is a typical tempered martensite in term of microstructure. They can be welded by many common welding methods including SMAW, SAW, GSAW (TIG/MIG), and FCAW, etc. Metals-Piping not only provides premium-quality T91/ P91 seamless pipes and tubes but also supplies optimum filler metals (welding wire, electrode, welding (pipe) What is p91 wall thickness?What is p91 wall thickness?P91 typically allows a wall thickness reduction by at least a 2-to-1 ratio. If the wall is thinner, hanger loads are lighter. Also, a wall that is 50 percent thinner takes less time to weld and uses less filler metal.
