ER307
A popular European grade used for automotive exhaust applications and dissimilar stainless grades.
ER308
Alloy 308 is used for TIG, MIG, and submerged arc welding of unstabilized stainless steels such as Types 301, 302, 304, 305, and 308. This filler metal is the most popular grade among stainless steels, used for general-purpose applications where corrosion conditions are moderate.
ER308H
Alloy 308H gives high carbon deposition (0.04% C min) for high temperature applications. This provides creep strength and tensile strength. It is used for joining dissimilar alloys such as 18-8, 19-9, and 20-10 or type 304/304H materials.
ER308L
Alloy 308L has the same analysis as type 308 except the carbon content has been held to a maximum of .03% to reduce the possibility of intergranular carbide precipitation. Ideal for welding Types 304L, 321, and 347 stainless steels. This is a suitable wire for applications at cryogenic temperatures.
ER308LHS
Alloy 308LHS is a stainless steel welding wire for MIG welding. This wire is used to weld equipment made with 304 and 308 stainless grades. Welding speed is higher than 308 or 308L due to improved wettability of weld metal.
ER309
This product is partially described with relation to 309L below.
ER309L
Alloy 309L is of similar composition as Alloy 309 except for the carbon content being lower than .03%. The lower carbon content reduces the possibility of intergranular corrosion. Alloy 309L is preferred over 309 for cladding over carbon or low alloy steels, as well as for dissimilar joints that undergo heat treatment.
ER309LHS
Alloy 309LHS is of the same chemical composition as 309L, with higher silicon content to improve the bead appearance and increase welding ease. The weld beads are exceptionally smooth due to good wetting.
ER309LMo
No description available at this time. The rod is available, though!
ER310
Alloy 310 is used for the welding of stainless steels of similar composition in wrought or cast form. The weld deposit is fully austenitic and calls for low heat during welding. This filler metal can also be used for dissimilar welding.
ER312
Alloy 312 is used to weld cast alloys of similar composition and is used to weld dissimilar metals and weld overlays. This alloy has very high ferrite. When welding similar cast alloys, limit welding to two or three layers only.
ER316
This product is partially described with relation to 316L below.
ER316L
Alloy 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.
ER316LHS
Alloy 316LHS is similar to 316L, with higher silicon content for optimum ease in welding and smooth bead appearance. Higher productivity could be realized in MIG welding.
ER317L
Alloy 317L is used for welding stainless steels with similar composition. Due to its higher molybdenum content, this alloy offers high resistance to pitting and crevice corrosion. Lower carbon makes the weld metal less susceptible to intergranular corrosion.
ER320LR
Alloy 320LR has a composition similar to Alloy 320, except that carbon, silicon, phosphorus, and sulfur levels are kept at lower levels as well as the columbium and manganese being specified at a narrower range. The low melting residuals are limited in this alloy to reduce the possibility of microfissuring. It is for this reason that this alloy is often used for welding Type 320 stainless steels.
ER321
No description available at this time. The rod is available, though!
ER330
Alloy 330 is used to weld cast and wrought material of similar chemical composition. The weld metal provides excellent heat and scale resistance up to 1800°F. However, high sulfur environments may adversely affect elevated temperature performance. This being a fully austenitic alloy, heat input is necessary.
ER347
Alloy 347 is a columbium-stabilized stainless steel welding wire used to weld Types 321 and 347. Addition of columbium reduces the possibility of chromium carbide precipitation and consequent intergranular corrosion.
ER383
No description available at this time. The rod is available, though!
ER385
Alloy 385 is used for welding materials of similar chemical composition which are used for fabrication of equipment and vessels for handling of sulfuric acid and many chloride containing media. This filler metal may also find applications for joining Type 317L material where improved corrosion resistance in specific media is needed. In order to reduce the propensity for fissuring and hot cracking, the low melting constituents such as carbon, silicon and phosphorus are controlled to lower levels in this alloy.
ER409Cb
Alloy 409Cb is a ferritic stainless steel welding wire which is used to weld type 409 and 409Ti base materials. Addition of columbium leads to a preferential reaction with carbon, saving chromium from forming carbides. This improves corrosion resistance, increases strength at high temperatures, and promotes ferritic micro-structure.
ER410
Alloy 410 is used to weld Types 403, 405, 410, and 416. It is also used for welding overlay on carbon steels to resist corrosion, erosion, or abrasion. This material, being an air hardening type, calls for preheating of the joint to 350°F before welding.
ER410NiMo
Alloy 410NiMo is used primarily to weld cast and wrought material of similar chemical composition. Preheating and interpass temperature of not less than 300°F are required.
ER420
Alloy 420 has a higher carbon content than Alloy 410. This alloy is often used for surfacing applications which call for superior resistance to abrasion. It requires preheat and interpass temperatures of not less than 400°F, followed by slow cooling. Post weld heat treatment is used to temper the weld deposit.
ER430
Alloy 430 is a ferritic stainless steel which offers good ductility in heat treated condition. In addition to the applications of welding similar alloys, it is also used for overlays and thermal spraying.
ER430LCb
Note: Technically, this specification does not meet any provided by the American Welding Society.
Alloy 430LCb is stabilized ferritic steel, which offers superior mechanical properties to 430 grade. In addition its fatigue resistance is also higher, the fact that lead to its spontaneous popularity in the automotive industry. This product is also used for overlay cladding as well as in thermal spray applications. Preheating of the joint to a minimum of 300°F is recommended. Welding must be done with very low heat input.

ER630
Alloy 630 is a precipitation hardening stainless steel used for welding of materials of similar chemical composition. Mechanical properties of this alloy are greatly influenced by the hat treatment.
ER2209
Alloy 2209 is a filler material designed to weld duplex stainless steels such as UNS Number N31803. The welds are characterized by high tensile strength and improved resistance to stress corrosion cracking and pitting. The wire is lower in ferrite compared to that of base metal in order to obtain improved weldability.
ER2553

ER2594
Alloy 2594 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 welding wire is overalloyed 2-3 percent in Nickel to provide the optimum ferrite/austenite ratio in the finished weld. This structure results in high tensile/yield strength and superior resistance to SCC and pitting corrosion.
ER3556
ER3556 alloy is an iron-nickel-chromium-cobalt alloy that combines effective resistance to sulfidizing, carburizing and chlorine-bearing environments at high temperatures with good oxidation resistance, fabricability, and excellent high-temperature strength. It has also been found to resist corrosion by molten chloride salts and other salts, and is resistant to corrosion from molten zinc.

17-4PH
Alloy 17-4PH is a precipitation hardening stainless steel used for welding of materials of similar chemical composition. Mechanical properties of this alloy are greatly influenced by the heat treatment.
RA330
RA330® alloy is an austenitic heat and corrosion resisting alloy offering an exceptional combination of strength and resistance to carburization, oxidation and thermal shock. Carburization and oxidation resistance to 2100°F (1148°C) are enhanced by a nominal 1.25% silicon addition. RA330 alloy finds wide application in high temperature industrial environments where good resistance to the combined effects of carburization and thermal cycling are required.
