AUTOTHERME GRADE-U(MOD)

AWS: SFA 5.23 EA3K

EN ISO CODE: 14171-B SU4M31

Copper Coated Low carbon, high manganese high Silicon, 0.5% Moly special purpose wire for submerged arc welding. The wire gives good radiographic quality deposits with excellent crack resistance and toughness.Autotherme Grade-U (Mod) is suitable for single, multi-pass welding especially suitable for two run technique, suitable for similar composition C-Mo steels, fine grained steels and equivalent grade steels like: Gr. F1 of SA- 182 and SA-336 Gr. A of SA-204, Gr. P1 pipe of SA-335, class 1 of A grade of SA-533, etc suitable for fabrication of heavy machinery, steel plant equipments & structures, high strength fabricated structures etc.
