AWS: ER309, ER309L

Select Product

Top Features

  • Designed to be used primarily with basic fluxes that recover nearly all of the wire chromium in the deposit
  • Low carbon content recommended where there is a risk of intergranular corrosion
  • Reduced carbon levels (0.03% max) that offers increased resistance to inter-granular corrosion

Typical Applications

  • ASTM A743, A744 Types CF-8 and CF-3 and ASTM A240 Type 309S
  • For joining carbon or mild alloy steel to austenitic stainless steels
  • Can also be used on "18-8" steels, since it overmatches the corrosion resistance, if the weldment will not be exposed to temperatures of 538°C to 927°C (1000°F to 1700°F)
  • Ideal for joining stainless steels to themselves or to carbon or low alloy steels, and can be used at temperatures up to 700°F (371°C)
