OK Tubrod 14.37
FCAW
Type Rutile
OK Tubrod 14.37 is a flux-cored, tubular wire developed for the welding of Duplex stainless steels and corresponding to ASTM A240S31803 and DIN 1.4462. The weld metal produced is of the 22Cr9Ni3Mo type which exhibits exeptional resistance to pitting and intergranular corrosion as well as stress corrosion cracking. Shielding gas CO2 or Ar+20% CO2.
