Application
ER317L is used for welding stainless steels with similar composition. Due to its higher molybdenum content, this alloy offers high resistance to pitting and crevice corrosion. Lower carbon makes the weld metal less susceptible to inter-granular corrosion.

Deposited Chemical Composition %(Typical)
C = 0.02	Mo = 3.40	P = 0.010
Cr = 18.50	Mn = 1.70	S = 0.012
Ni = 13.20	Si = 0.40

 

Mechanical Properties (R.T.)
Yield Strength	55,000psi
Tensile Strength	87,000psi
Elongation	47%
Reduction of Area	70%

Deposited All Weld Metal Properties
Data is typical for ER317L 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.
