Stainless Steel Electrodes E347-16

Stainless steel electrode can be divided into chromium stainless steel electrode and chromium nickel stainless steel electrode, these two types of electrodes in accordance with the national standard, are in accordance with GB/T983 -1995 assessment. Chromium stainless steel has certain corrosion resistance (oxidizing acid, organic acid, cavitation) heat resistance and corrosion resistance. It is usually selected as equipment material for power station, chemical industry, petroleum and so on. But chromium stainless steel generally poor weldability, should pay attention to the welding process, heat treatment conditions and the selection of appropriate electrode. Chromium-nickel stainless steel electrode has good corrosion resistance and oxidation resistance, widely used in chemical industry, fertilizer, petroleum, medical machinery manufacturing. In order to prevent the corrosion between the eyes due to heating, welding current should not be too large, less than carbon steel electrode about 20% , arc should not be too long, quick cooling between layers, to narrow bead is appropriate.
