E71T-1C and E71T-1M,Shielding gas designator.2 Indicates the type of shielding gas used for classification. The letter“C” indicates that the electrode is classified using 100% CO2 shielding gas. The letter “M” indicates that the electrode is classified using 75–80% Argon/balance CO2 shielding gas. When no designator appears in this position, it indicates that the electrode being classified is self-shielded and that no external shielding gas was used.

The first two designators may be“ER”for solid wires that may be used as electrodes or rodsor they may be“EC’for composite cored or stranded wires;or they may be“EQ”for strip electrodes.

The three- or four-digit number,such as 308 in ER308,designates the nominal chemical composition of the filler metal.

• ER307.The nominal composition(wt.%)of this classification is 21 Cr.9.5Ni.4 Mn.1 Mo.Filler metals .

• ER308The nominal composition(wt.%)of this classification is 21 Cr10 Ni.Commercial specifications is most often used to weld base metals of similar composition, in particular, Type 304.
