Description

ER309L is a low-carbon austenitic stainless steel welding wire designed for welding 309 and 309L stainless steels, as well as dissimilar metals. The low carbon content reduces the risk of carbide precipitation, ensuring excellent weld strength and resistance to intergranular corrosion. ER309L is widely used in high-temperature applications and in industries where corrosion resistance and weld quality are critical.

KEY FEATURES

  • Low Carbon Content: Contains less than 0.03% carbon, which minimizes the risk of carbide precipitation and ensures better weld integrity, especially for applications exposed to high temperatures.
  • Superior Corrosion Resistance: Provides outstanding resistance to corrosion and oxidation, especially in environments where high temperatures and aggressive chemicals are present.
  • High Strength and Durability: Offers good tensile strength and high-temperature strength, ensuring durability in demanding applications.
  • All position welding
  • Suitable for  chemical and petrochemical industry,power generation,heavy equipment and structural applications
  • Shielding gas: (TIG)100%Ar , (MIG)Ar+1-2%O2 

DIAMETER

  • MIG: 0.6-1.2 （mm) / 0.023“,0.030″,0.035″,0.040“,0.045″
  • TIG: 1.6-4.8 (mm) / 1/16″,3/32″,1/8″,5/32″,3/16″
