Additional classifications for filler materials used in welding according to ASME/AWS standards

• A: ASME/AWS SFA/A 5.4, Classification E309-XX
• B: ASME/AWS SFA 5.11, Classification ENiCrFe-2 or -3 or ENiCrMo-3 (see Note 4)
• C: ASME/AWS SFA 5.4, Classification E410-XX (0.005 % C max) (heat treatment at 1400 °F required)
• D: ASME/AWS SFA 5.4, Classification E308-XX
• E: ASME/AWS SFA 5.4, Classification E347-XX
• F: ASME/AWS SFA 5.4, Classification E316-XX
• G: ASME/AWS SFA 5.4, Classification E316L-XX
• H: ASME/AWS SFA 5.4, Classification E308L-XX
• J: ASME/AWS SFA 5.4, Classification E317L-XX
• K: ASME/AWS SFA 5.4, Classification E308H-XX
• L: ASME/AWS SFA 5.4, Classification E310-XX

Notes:

1. This table refers to coated electrodes. For bare wire or cored welding (SAW, GMAW, GTAW, FCAW), use equivalent electrode classifications (ASME/AWS SFA 5.9, SFA/A5.14, SFA/A5.22, SFA/A5.34). Refer to the text for information on other processes. Either ER347 or ER321 may be used for GTAW or PAW of Type 321 stainless steel.
2. The higher alloy electrode specified in the table is normally preferred.
3. See Section 5.12 on filler temperature requirements.
4. See Table 1 for high temperature limitation for nickel-base filler metals.
5. E16-8-2 is often specified when the weld deposit will be exposed to high creep strains where sigma phase may affect performance.
