ASME SFA 5.9
ISO 14343-A W 23 12 2 L
ER309LMo contains an increase in Mo, compared to alloy ER309, which allows for an increase in its pitting corrosion resistance. Due to its low carbon content there is a decrease in the likelihood on intergranular carbide precipitation. This alloy is in overlay cladding as well as for austenitic ferritic joints with a maximum heat application of 572°F. ER309LMo can also be used to join low-alloy steels or stainless/ heat resistant chromium steels to austentitic steel grades.
