ER 309LSi
Alloy ER309LSi Welding data
Weld Process:
Used for Mig, Tig & Submerged arc
Deposited All Weld Metal Properties:
Data is typical for ER309LSi 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-309LSi is suitable for joining Stainless steels of the 304 type and 347 type. The higher silicon gives are stability and exceptinally smooth bead appearance.
