E347-16
Alloy Type: A5.4, STAINLESS STEEL Covered Arc Welding Electrodes
E347-16 delivers outstanding performance, especially for projects that require you to do a lot of out-of-position welding. This electrode allows you to weld stabilized austenitic 18Cr-8Ni steels, including those with grades of either the columbium (347) or titanium (312) type. E347-16 offer excellent resistance to sensitization during high temperature service.
Typical Applications: process piping, power generation equipment, food processing, pharmaceutical equipment
