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 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.

Other shielding Gases may be used for Mig welding. Shielding gases are chosen taking Quality, Cost, and Operability into consideration

Recommended Welding Parameters
SAW “Submerged Arc Welding Process”   REversed Polarity Suggested
Wire Diameter Amps Volts
3/32 250-450 28-32
1/8 300-500 29-34

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.
