Introduce: 

ER309/ER309L is similar in composition to E309/309L, with the minor difference of the carbon being lower than 0.03% in ER309/ER309L. The lower carbon content allows for a reduction in the likelihood of intergranular carbide precipitation without having to use a stabilizer such as titanium. Filler metals of this classification are commonly used for welding similar alloys in the wrought or cast form. They are also used to weld Type 304 and similar base metals where severe corrosion conditions exist requiring higher alloy weld metal. They are used in dissimilar metal welds, such as joining Type 304 to carbon steel. This grade may be used for joining and overlay of stainless steels similar in composition. ER309L is ideal for industrial and furnace boiler parts, annealing chambers, heat exchangers, and fused salt treatment installations.

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.
