Product Description

Class: ER308LSI

AWS: A5.9

Conforms to Certification: AWS A5.9        ASME SFA A5.9

Weld Process Used for Mig (GMAW) and Submerged Arc (SAW)

AWS Chemical Composition
C = 0.03 max
Cr = 19.5 – 22.0
Ni = 9.0 – 11.0
Mo = 0.75 max
Mn = 1.0 – 2.5
Si = 0.65 – 1.0

Available Sizes – Diameter X Spool Sizes
.025 x 2#, 10#, 25#
.030 x 2#, 10#, 25#, 30#, 33#
.035 x 2#, 10#, 25#, 30#, 33#
.045 x 2#, 10#, 25#, 30#, 33#
1/16 x 10#, 25#, 30#, 33#

Application
WW308LSI is suitable for joining stainless steels of the 304 type and 308 types. Welding speed is higher that 308 or 308L due to improved weldability of the weld metal.

Deposited Chemical Composition % (Typical)
C = 0.016	Si = 0.85	Mn = 1.65
P = 0.016	S = 0.008	Cr = 20.65
Ni = 10.0

 

Mechanical Properties (R.T.)
Yield Strength	59,000 psi
Tensile Strength	87,000 psi
Elongation	39%
Reduction of Area	60%

Deposited All Weld Metal Properties
Data is typical for ER308LSI weld metal deposited by Mig using Argon + 2% oxygen as the shielding gas. Data on sub-arc is not presented, as sub-arc is dependent on the type of flux used.
