Application
ER316L filler metal is primarily used for welding low carbon molybdenum-bearing austenitic alloys. This low carbon alloy is not as strong at elevated temperatures as ER316H.

Deposited Chemical Composition % (Typical)
C = 0.015 Mo = 2.50 P = 0.010
Cr = 18.75 Mn = 1.80 S = 0.010
Ni = 12.25 Si = 0.34

 

Mechanical Properties (R.T.) 
Yield Strength 59,000psi
Tensile Strength 88,000psi
Elongation 35%
Reduction of Area 39%

Deposited All Weld Metal Properties
Data is typical for ER316L weld metal deposited by Tig using 100% Argon as the shielding gas.

Recommended Welding Parameters
GTAW “Tig Process”
Wire Diameter Amps DCSP Volts Shielding Gas
.035 60-90 12-15 Argon 100%
.045 80-110 13-16 Argon 100%
1/16 90-130 14-16 Argon 100%
3/32 120-175 15-20 Argon 100%

Note: Parameters for tig welding are dependent upon plate thickness and welding position.
Other shielding Gases may be used for Tig welding. Shielding gases are chosen taking Quality, Cost, and Operability into consideration.
