Stainless Steel Mig ER316L Mig Welding Wire. 035 - 10 lb Spool 316L has the same analysis as ER316, except that the carbon content is limited to a maximum of 0.03% in order to reduce the possibility of formation of intergranular carbide precipitation. This filler metal is primarily used for welding low carbon molybdenum-bearing austenitic alloys. This low carbon alloy is not as strong at elevated temperatures as ER316H. Damage inflicted by the user is not covered. Your satisfaction is our priority.
