TERROWELD S1
 
Stainless Steel Electrode for Heat and Corrosion
Terroweld S1 is an all-purpose stainless steel electrode having a high corrosion and heat resistance, which can be operated at very low heat input. It is specially recommended for repairing and joining extra low carbon grades of stainless steels, where a combination of corrosion resistance, heat resistance and scaling resistance is called for.
 
ALLOY BASE
Fe, Cr, Ni
 
SPECIAL FEATURES
  • VacPac for ready use - without preheating within 8 hours
  • Superior welding characteristics
  • Finely rippled bead with minimum spatter
  • All positions
APPLICATIONS
Terroweld S1 is recommended for welding all austenitic stainless steels of 18/8 and 19/9 types, particularly the ELC grades, and can be used for joining and repairing of mixers, valves, sterilizers etc., in dairy, chemical and distillery equipment. The electrode can also be used as a preventive overlay on steel.
 
PROPERTIES
UTS : 50-57 kg / mm2
Elongation : 38-44%
 
WELDING PROCEDURE
  • The weld area should be cleaned of all dirt, grease and oil
  • Stringer bead welds are preferable, maintaining a short arc
  • Use smaller size of electrode wherever practicable
