Weld Process: Shielded Manual Metal Arc

AWS Chemical Composition Requirements
C = 0.03 max Si = 0.90 max
Cr = 26.5 – 29.0 P = 0.02 max
Ni = 30.0 – 33.0 S = 0.02 max
Mo = 3.2 – 4.2 Cu = 0.6 – 1.5
Mn = 0.5 – 2.5

Application
DURAMAX E383-16 the nominal composition (wt %) of this weld metal is 28 Cr, 31.5 Ni, 3.7 Mo, 1 Cu. These electrodes are used to weld base metal of a similar composition to itself and to other grades of stainless steel. DM383-16 weld metal is recommended for sulfuric and phosphoric acid environments. The elements C, Si, P and S are specified at low maximum levels to minimize weld metal hot cracking and fissuring (while maintaining the corrosion resistance) frequently encountered in fully austenitic stainless steel weld metals.
