AFM E6010P  Mild Steel & Low Hydrogen Electrodes
AFM E6010P is a modified version of AFM E6010 electrode and can be differentiated by the gray coating. It has better restriking capabilities, lower spatter, and a better bead profile. It can be used for welding in the flat, vertical-up, vertical-down and overhead positions with DC reverse polarity.  
AFM E6010 Mild Steel & Low Hydrogen Electrodes
AFM E6010 is a high cellulose coated ˇ°fast-freezeˇ± electrode. It produces a deep penetrating, forceful, spray type arc and readily removable, thin, friable slag which may not seem to completely cover the weld bead. It can be used for welding in the flat, vertical-up, vertical-down and overhead positions with DC reverse polarity.  
AFM E6011 Mild Steel & Low Hydrogen Electrodes
AFM E6011 is a high-cellulose potassium electrode designed to be used with AC current and to duplicate the usability characteristics and mechanical properties of AFM E6010. Although AFM E6011 is usable with dcep (electrode positive), a decrease in joint penetration will be noted when compared to AFM E6010.
AFM E6013  Mild Steel & Low Hydrogen Electrodes
AFM E6013 is a versatile electrode with a wide variety of applications for light gauge and heavy plate. Slag removal is easy, often is self cleaning on heavy plate, and has a smooth arc transfer with a fine ripple bead appearance.
AFM E7014   Mild Steel & Low Hydrogen Electrodes
AFM E7014 is similar to AFM E6013, but with the addition of iron powder for obtaining higher deposition efficiency. The iron powder also permits the use of higher welding currents.
AFM E7018-1   Mild Steel & Low Hydrogen Electrodes
AFM E7018-1 is an all position low hydrogen iron powder electrode that is intended for welds requiring a lower transition temperature than is normally available from E7018 electrodes. It is designed to have the same usability and weld metal composition as AFM E7018, except that the manganese content is set at the high end of the range.
AFM E7018-A1 Mild Steel & Low Hydrogen Electrodes
AFM E7018-A1 electrodes are very similar to AFM E7018, except that 1/2% molybdenum has been added. This addition increases the strength of the weld metal, especially at elevated temperatures, and provides some increase in corrosion resistance; however, it may reduce the notch toughness of the weld metal.
AFM E7018-B2L Mild Steel & Low Hydrogen Electrodes
AFM E7018-B2L replaces E8018-B2L under AWS A5.5-81. The strength designations and room-temperature strength requirements after postweld heat treatment have been reduced to reflect the fact that commercial products have been producing marginal tensile strength results in classification tests over many years. The base metals with which this classification is generally used have lower strength requirements than were reflected by the former electrode classification. The lower carbon in the weld metal will improve ductility and lower hardness, but will also reduce the high-temperature strength and creep resistance of the weld metal.
AFM E7018 Mild Steel & Low Hydrogen Electrodes
AFM E7018 is an all position iron powder, low hydrogen electrode that may be used with AC or DC reverse polarity.
AFM E7024  Mild Steel & Low Hydrogen Electrodes
AFM E7024 is a high speed, heavy-coated, iron powder electrode. The coverings usually amount to about 50% of the weight of the electrode, resulting in higher deposition efficiency.
AFM E8018-B2 Mild Steel & Low Hydrogen Electrodes
AFM E8018-B2 is a low hydrogen electrode that may be used with AC or DC reverse polarity. It is different from ˇ°fast freezeˇ± electrodes in that the weld metal freezes quite rapidly even though the slag is relatively fluid.
AFM E8018-B3L Mild Steel & Low Hydrogen Electrodes
AFM E8018-B3L is similar to AFM E9018-B3, except that the carbon content is reduced to .05 maximum. This classification replaces E9018-B3L under AWS A5.5-81. The strength designations and room-temperature strength requirements after postweld heat treatment have been reduced to reflect the fact that commercial products have been producing marginal tensile strength results in classification tests over many years. The base metals with which this classification is generally used have lower strength requirements than were reflected by the former electrode classification. The lower carbon in the weld metal will improve ductility and lower hardness, but will also reduce the high-temperature strength and creep resistance of the weld metal.
