GFW310E
Applicable Specification
JIS Z3323 TS310-FC0
AWS A5.22 E310T0-1
Applications and Characteristics
TASETO GFW310E is used for welding AISI310 or SUS310S and welding dissimilar metals such as stainless steel and carbon steel combinations. Weld metal has excellent corrosion resistibility and heat resistance, because of the higher content of Cr and Ni than Type 308 weld metal.
Notes on Usage
Please refer to “Guideline for Welding Stainless Steel with GFW Wires”.
* Because of the fully austenitic structure of weld metal, the weld metal susceptibility to hot cracking is high. So, the welding current must be kept within 150～200A. In the case of highly restrained conditions, it must be kept within 150～170A. Keep the interpass temperature at 120℃ or below. To minimize crater cracks, fill craters with filler metal and remove crater cracks with a grinder.
Use 100%CO2 as shielding gas.

GFW2594
Applicable Specification
JIS Z 3323 TS329J4L-FC0
AWS A5.22 E2594T0-1
Applications and Characteristics
TASETO GFW2594 is used for welding of super duplex stainless steel such as UNS S32750, and S32760. As weld metal has a higher pitting resistance equivalent (PRE※) value than that of GFW329J4L, GFW2594 is suitable for more corrosive environment.
※ PRE = Cr% + 3.3xMo% + 16xN%
Notes on Usage
Preheating is not necessary and interpass temperature should be kept under 150℃.
Post-weld heat treatment causes severe embrittlement of weld metal.
Use 100%CO2 as shielding gas.
