Welding electrode AWS A5.9 class ER316L

Class: ER316L

AWS: A5.9

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

Weld Process Used for GTAW, MIG (GMAW) and Submerged Arc (SAW)

AWS Chemical Composition Requirements

  • C = 0.03 max
  • Cr = 18.0 – 20.0
  • Ni = 11.0 – 14.0
  • Mo = 2.0 – 3.0
  • Mn = 1.0 – 2.5
  • Si = 0.30 – 0.65
  • P = 0.03 max
  • S = 0.03 max
  • Cu = 0.75 max

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
  • Tensil Strength 88,000psi
  • Elongation 35%
  • Reduction of Area 39%
