Purpose
① Welding of 18%Cr-12%Ni-2% Mo stainless steels for high temperature service.
Attribute
① Designed for welding with 100% CO2 or Ar+15~25%CO2 shielding gas
② Excellent all position weldability
③ Smooth and stable arc with a fast freezing slag
Purpose
① Welding of dissimilar metals such as stainless steel and carbon steel or stainless steel and low alloy
Attribute
① Designed for welding with 100% CO2 or Ar+15~25%CO2 shielding gas
② Excellent all position weldability
③ Smooth and stable arc with a fast freezing slag
Purpose
① Welding of 18%Cr-8%Ni stainless steels for high temperature service
Attribute
① Designed for welding with 100% CO2 or Ar+15~25%CO2 shielding gas
② Excellent all position weldability
③ Smooth and stable arc with a fast freezing slag
Caution
① Keep preheating and interpass temperature to be more than 150℃(302℉).
② PWHT at 850℃(1,562°F) will improve mechanical properties and corrosion resistance.
③ As there is higher chance of cracks for this grade, extra care is needed when welding. ④ Use Ar or Ar + 2-5% O₂ mixed gas.
Purpose
① Stainless steels 409, 430, 436, 439 Type • Automotive mufflers
Attribute
