Description: AFM E320LR-16 weld metal deposits have the same basic composition as that
deposited by AFM E320-16; however, the elements of C, Si, P, and S are specified
at lower maximum levels, and Cb (Nb) and Mn are controlled within narrower
ranges. These changes reduce the weld metal fissuring (while maintaining the
corrosion resistance) frequently encountered in fully austenitic stainless steel
weld metals. Consequently, welding practices typically used to deposit
ferrite-containing austenitic stainless steel weld metals can be used. AFM
E320LR-16 has a lower minimum tensile strength than AFM E320-16.
