TERROWELD S3
 
Stainless Steel Electrode for Oxidation Resistance
Terroweld S3 is an all-purpose high alloy stainless steel electrode having high corrosion and heat resistance, which can be operated at low heat input. This electrode is specially recommended for repairing and joining of heat resistant stainless steel plates and pipes for protection against oxidation and corrosion. It is also suitable for joining dissimilar metals and overlays.
 
ALLOY BASE
Fe, Cr, Ni
 
SPECIAL FEATURES
  • VacPac for ready use - without preheating within 8 hours
  • Suitable for all position welding
  • Finely rippled bead with minimum spatter and easy detachability of slag
APPLICATIONS
Terroweld S3 is recommended for welding all austenitic stainless steels for heat & oxidation resistance upto 1100C in dairy, chemical & distillery equipment for applications like valves, heat exchangers etc.
