Gemet 821N, ENiCrFE-3
CLASSIFICATION
AWS SFA 5.11 ENiCrFe3, CEN ENi6182 NiCr15Fe6MnB12
Werkstoff no 2.4807.
DESCRIPTION
A versatile non-synthetic electrode for welding of Inconel 600 and similar composition alloys. Medium heavy coated, basic type all- position electrode manufactured by using inconel core wire intended for welding Inconel 600 and similar composition alloys. The deposit tolerates high dilution levels and is very resistant to hot cracking. It is not susceptible to sigma phase embrittlement or carbon migration and is therefore ideal for service at elevated temperatures. The weld metal passes X-ray quality.
