Stainless Steel TIG Wire 309

309 TIG Wire is for use when welding low carbon 22%Cr-8%Ni steel and dissimilar stainless steels.

• Can be used at temperatures of up to 371°C.
• Reduced carbon levels offer increased resistance to inter-granular corrosion.
• 309Lsi is suitable for joining material of similar composition and also dissimilar Stainless Steels.
• Contains higher Chromium and Nickel. High Silicon levels improve weld pool fluidity.
•  Ideal for use in the chemical and power generation industries, and for general repair and maintenance
