SelectAlloy 309H-AP

Stainless Steel / Flux Cored / Gas Shielded


Features

  • The added C provides higher tensile and creep strength at elevated temperatures.
  • Designed for welding in all positions where well washed beads can be achieved with minimal weaving in both 100% CO₂ or 75-80% Ar/balance CO₂ shielding gas
  • Applications for this alloy are in the welding of components of similar composition used in the refinery and chemical processing equipment where higher temperature strength is required. This alloy is suitable for welding of 24 Cr 12 Ni wrought and cast grades for corrosion and oxidation resistance.
