- Applications
- WT-2553 is designed for the welding of 25%Cr-9%Ni-3%Mo-Cu super duplex stainless steels and this typical application is chemical plant and shipbuilding as well as nuclear plant industries. (UNS S32520, UNS S32550, S32750, S32900, JIS 329J4L)
- Characteristics on Usage
-
- - WT-2553 is a rutile type of flux cored wire for all-position welding.
- - It has low spatter generation, easy slag removal and good weld soundness.
- - It is excellent in pitting corrosion resistance and stress corrosion cracking resistance.
- Notes on Usage
-
- - The shielding gas should be used 100% CO2 or Ar+20~25%CO2 for welding.
- - Gas flow rate is proper 20~25ℓ/min.
- Sizes Available and Recommended Currents ( DC + )
