AFM ER2209 AFM ER2209 is used primarily to weld duplex stainless steels which contain approximately 22 percent of chromium such as UNS S31803 (alloy 2205).
AFM ER2594 Superduplex grade 2594 electrodes provide matching chemistry and mechanical property characteristics to wrought superduplex alloys such as 2507 and Zeron 100 as well as superduplex casting alloys (ASTM A890).
AFM ER308 AFM ER308 is used for welding alloys 18-8, 19-9, and 20-10 such as AISI 201, 202, 204, 301, 302, & 304 grades.
AFM ER308H This classification is the same as AFM ER308, except that the allowable carbon content has been restricted to the higher portion of the 308 range
AFM ER308L This classification is the same as AFM ER308, except for the carbon content. Low carbon (0.03 percent max.) in AFM ER308L reduces the possibility of intergranular carbide precipitation
AFM ER308LSi This classification is the same as AFM ER308L, except for the higher silicon content.
AFM ER309 AFM ER309 is used to weld alloy 309
AFM ER309L This classification is the same as AFM ER309, except for the carbon content. Low carbon (0.03 percent max.) in AFM ER309L reduces the possibility of intergranular carbide precipitation
AFM ER309LSi The classification is the same as AFM ER309L, except for higher silicon content.
AFM ER310 AFM ER310 is used for welding 310 stainless
AFM ER312 AFM ER312 was originally designed to weld cast alloys of similar composition
AFM ER316 AFM ER316 is used for welding Type 316 and similar alloys.
AFM ER316H AFM ER316H is the same as AFM ER316, except that the allowable carbon content has been restricted to the higher portion of the 316 range
AFM ER316L This classification is the same as AFM ER316, except for the carbon content. Low carbon (0.03 percent max.) in AFM ER316L reduces the possibility of intergranular chromium carbide precipitation and thereby increases the resistance to intergranular corrosi
AFM ER316LSi This classification is the same as AFM ER316L, except for the higher silicon content.
AFM ER317L AFM ER317L is used to weld 316 and 317 base metals. Low carbon (0.03 percent max.) in AFM ER317L reduces the possibility of intergranular carbide precipitation.
AFM ER320 AFM ER320 is primarily used to weld base metals of similar composition, such as alloy 20, for applications where resistance to severe corrosion is required for a wide range of chemicals including sulfuric and sulfurous acids and their salts.
AFM ER320LR AFM ER320LR weld metal deposits have the same basic composition as that deposited by AFM ER320; however, the elements of C, Si, P, and S are specified at lower maximum levels, and Cb (Nb) and Mn are controlled within narrower ranges.
AFM ER330 AFM ER330 is commonly used where heat and scale resisting properties above 1800°F (980°C) are required, except in high-sulphur environments, as these environments may adversely affect elevated temperature performance.
AFM ER347 AFM ER347 is usually used for welding alloys 321 and 347.
AFM ER347Si AFM ER347Si is the same as AFM ER347, except for the higher silicon content.
AFM ER385 (904L) AFM ER385 is used primarily for welding of ASTM B625, B673, B674, and B677 (UNSN08904) materials for the handling of sulfuric acid and many chloride containing media.
AFM ER409Nb AFM ER409Nb is the same as ER409 except that niobium (columbium)is used instead of titanium to achieve similar results
AFM ER410 AFM ER410 is used to welding 403, 405, 410, and 416 stainless
AFM ER410NiMo AFM ER410NiMo is primarily designed for welding ASTM CA6NM castings or similar material, as well as light gage 410, 410S, and 405 base metals.
AFM ER420 AFM ER420 is similar to AFM ER410, except for slightly higher chromium and carbon contents.
AFM ER430 Welding with AFM ER430 usually requires preheating and postweld heat treatment.
AFM ER630 AFM ER630 is designed primarily for welding ASTM A564 Type 630 (alloy 17-4PH) and some other precipitation-hardening stainless steels
