AWS A5.9 ER307Si

A 5kg pack of 307SI Stainless Steel TIG Welding Rods available in a variety of diameters.  Designed for welding between dissimilar steel and stainless steel, additionally used in applications such as joining and surfacing of steels that can be work hardened.

Excellent resistance to corrosive and atmospheric conditions make 307SI welding wire a popular choice for industries where these factors may compromise weld integrity.  These industries include chemical, pharmaceutical, petrochemical, power, and engineering, plus many more. Due to the high levels of manganese, the finished weld metal has excellent crack resistance and high mechanical strength.


In addition to having excellent crack resistance, good mechanical strength and the ability to produce porosity free weld deposits, these welding rods have a high silicon content which provides a smooth weld deposit appearance. Furthermore, they also have high ductility which ensures the finished weld will withstand the effects of bending, stretching or misshaping without compromisation. Perfect for depositing stress relaxing buffer layers on base metals with a greater degree of crack sensitivity including hardfacing.

Available in 5kg packs in the following diameter options -:

  • 0.8mm
  • 1.0mm
  • 1.2mm
  • 1.6mm
  • 2.4mm
  • 3.2mm

Wide ranging applications including buffer layers for hardfacing, dissimilar welding between steel and stainless steel, armour plate, exhaust systems (type 409,304), high Manganese austenitic steel, heterogeneous welding (joining base metals with a significantly different composition to the welding filler material), difficult to weld steels and tool steels.  Used extensively in a wide variety of industries.
