Application
ER308L has the same analysis as type 308 except the carbon content has been held to a maximum of .03% to reduce the possibility of intergranular carbide precipitation. ER308L is ideal for welding Types 304L, 321, and 347 stainless steels. This is a suitable wire for applications at cryogenic temperatures.

Deposited Chemical Composition % (Typical)

C = 0.02 Si = 0.32 Mn = 1.70 P = 0.011 S = 0.009 Cr = 20.0 Ni = 10

 

Mechanical Properties (R.T.)  

Yield Strength 57,000 psi Tensile Strength 87,000 psi Elongation 34% Reduction of Area 56%

Deposited All Weld Metal Properties
Data is typical for ER308L 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.

Both Agglomerated and fused fluxes can be used for submerged arc welding.
Note: The chemical composition of the flux mainly affects the chemistry of the weld metal and consequently its corrosion resistance and Mechanical properties.
