ER309L Filler Rod
Description
Filler metal particularly suitable for MIG welding. It can also be used for TIG and Plasma welding.
Deposit Properties
The following values are typical for MIG weld deposits without heat treatment, using an argon + 2% oxygen gas mixture, and TIG or Plasma welding with pure argon gas.
Microstructure
Austenitic matrix with a ferrite content of 11 FN according to the DeLong diagram, and 10.5 FN tested using a Magne-Gage device.
Corrosion Resistance
ER309L is used for welding stainless steels to low-alloy or alloy steels where corrosion resistance is of secondary importance.
TIG Welding
The appropriate polarity is Straight Polarity / Direct Current Electrode Negative (DCEN), and the shielding gas is pure argon. TIG welding parameters largely depend on material thickness and application.
Applications
ER309L is suitable for joining dissimilar steels and 24Cr/12Ni type stainless steels.
