AWS Class ER330
ASME SFA 5.9
ER330 is made to weld wrought and cast material of metal composed of similar compositions. ER330 has a good heat and scale resistance at a maximum of 1800°F, although this metal’s high temperature performance can be unfavorably affected in high sulfur environments. Also the heat input on this alloy should be kept to a minimum to decrease the likelihood of micro-fissures.
Tensile Strength: 84,000 psi
Yield Strength: 56,500 psi
