Product Code : ER309/309L
Product Description

ER309/309L is very similar to type 309 except for the carbon content being lower than .03%. The extra low carbon content provides good resistance to carbide precipitation and intergranular corrosion. ER309L works well for dissimilar joints that undergo heat treatment.
