ER 309L
Alloy ER309L Welding data
Weld Process:
Used for Mig, Tig & Submerged arc
Deposited All Weld Metal Properties:
Data is typical for ER309L weld metal deposited by mig using Argon+2% oxygen and Tig using 100% Argon as the shielding gas. Data on Sub-arc is not presented, as sub-arc is dependent on the type of flux used.
Application:
ER-309L has the same qualities as ER-309 but with the lower carbon content deemed necessary in many chemical application ER-309L preferred over ER-309 for cladding over carbon or low alloy steel, or dissimilar joints that are heat treated.
