E308/308L-16 is a low carbon electrode used to weld Types 304L and 347. The weld deposit contains a maximum of .04% carbon, which minimizes the formation of chromium carbides, and consequent susceptibility to intergranular corrosion. The weld deposit, with controlled ferrite, gives excellent notch toughness at -320°F (-196°C).

E309/309L-16 gives a weld deposit similar to 309, with reduced carbon levels (0.04% maximum) that offer increased resistance to intergranular corrosion. Type 309/309L is ideal for joining stainless steel to themselves or to carbon or low alloy steels. Alloy 309L is preferred to Alloy 309 for cladding over carbon or low alloy steels, as well as for dissimilar joints which undergo heat treatment.

E310-16 electrodes are used to weld stainless steels of similar composition in wrought and cast form. The weld deposit is fully austenitic, and as such calls for minimum heat input during welding.
E312-16 electrodes are used for welding wrought and cast alloys of similar composition as well as for welding dissimilar metals. The weld deposits exhibit high tensile strength and offer good resistance to abrasion.
E316/316L-16 electrodes are similar to that of Type 316, except the carbon is limited to a maximum of 0.04%. Precise control of the carbon content in Alloy 316/316L electrodes provides a weld deposit matching the corrosion resistant qualities of Type 316/316L stainless steel. The extra low carbon content reduces the possibility of carbide precipitation and consequent intergranular corrosion.

The weld deposit of
Alloy 317L is similar to that of Type 317, except the carbon is limited to a maximum of 0.04%. In addition to the resistance to pitting and crevice corrosion, this consumable offers good resistance to intergranular corrosion.

E320LR-16 is similar in composition to Alloy 320, with carbon, silicon, phosphorus, and sulfur controlled to lower limits and columbium and manganese kept to a narrower range. This composition is designed to reduce the possibility of microfissuring; however, low heat input is advisable for welding.
E330-16 electrodes are used to weld wrought and cast forms of stainless steel of similar chemical composition, which offer good heat and scale resistance above 1800°F (980°C). However, high sulfur environments adversely affect the high temperature performance. The heat input has to be kept to a minimum during welding to avoid the possibility of microfissuring.
E347-16 electrodes are columbium stabilized stainless steel electrodes used for welding Types 347 and 321 stainless and stainless clad steels. The columbium content is approximately ten times the carbon content, and when this product is used to weld stabilized Type 347 or 321 parent metal, it precludes intergranular corrosion under severe operating conditions.
E385-16 is used for welding materials of similar chemical composition (UNS Number N08904). These materials are used in fabrication of equipment and vessels for handling and storing sulfuric acid and phosphoric acid. The weld metal is fully austenitic and, as such, the low melting constituents such as carbon, silicon, and phosphorus should be kept low. Welding must be done with low heat input, using stringer bead technique.
E410-16 is designed to weld stainless steels of similar chemical composition as well as to overlay carbon steels to impart corrosion, erosion, and abrasion resistance. This material, being an air-hardening type, calls for a preheat and interpass temperature of not less than 400°F (200°C) during welding.
E410NiMo-16 is designed to weld materials of similar chemical composition in cast and wrought forms. Preheat and interpass temperatures of not less than 300°F (150°C) are recommended during welding.
E430-16 is designed to weld materials of similar chemical composition as well as overlay on carbon steels. The undiluted weld metal is ferritic, but with the dilution from mild or low alloy steel, it could become martensitic. Therefore, preheating and interpass temperatures of 300°F (150°C) during welding are recommended.

E2209-16 is used to weld duplex stainless steels such as UNS Number N31803. The welds offer excellent resistance to stress corrosion cracking and pitting. The micro-structure of the weld metal consists of austenite and ferrite. The ferrite of weld metal will be lower than the ferrite of Type 2205 base metal. Welding of duplex stainless steels calls for controlled parameters to achieve specified mechanical and corrosion resistance properties.

E2594-16 is a superduplex grade electrode that provides matching chemistry and mechanical property characteristics to wrought superduplex alloys such as 2507 and Zeron 100, as well as to superduplex casting alloys (ASTM A890). The electrode is overalloyed 2% to 3% in nickel to provide the optimum ferrite/austenite ratio in the finished weld. This structure results in high tensile and yield strengths and superior resistance to SCC and pitting corrosion.
