Deposited All Weld Metal Properties:
Data is typical for ER308LSi weld metal deposited by mig using Argon+2% oxygen and Tig using Argon as the shielding gas. Data on Sub-arc is not presented, as sub-arc is dependent on the type of flux used.
ER308Si is suitable for joining stainless steel of the 304 type and 308 types.welding speed is higher that 308 or 308L due to improved weldability of the weld metal.
Mechnical Properties (R.T.): Yield strength > 380 MPa Tensile strength > 610 MPa Elongation > 39% Reduction of area > 65% Impact value > -196°C (35-55 Joules)
