Stainless steel electrode can be divided into chromium stainless steel electrode and chromium nickel stainless steel electrode, these two kinds of welding electrode in the national standard, Jinqiao Tianjin welding rod factory are in accordance with the national standard GB/T983-1995. Chromium stainless steel has a certain corrosion resistance (oxidizing acid, organic acid, cavitation), heat resistance and corrosion resistance. Usually used in power plants, chemical, oil and other equipment materials. However, the general situation of chromium stainless steel can not be welded, should pay attention to the welding process, heat treatment conditions and selection of suitable welding electrode. Chromium nickel stainless steel electrode has good corrosion resistance and oxidation resistance, widely used in chemical, chemical fertilizer, oil, medical machinery manufacturing. In order to prevent eye corrosion due to heating, the welding current should not be too large, less than about 20% carbon steel electrode, the arc layer should not be too long, fast cooling, narrow welding bead.

In the standard GB/T983 of stainless steel electrode, the method of the welding rod is provided with a definite method. Stainless steel electrode type in the letter "E" said electrode, "E" behind the digital representation of the chemical composition of metal chemical composition, code, if there are special requirements of the chemical composition, with the element symbol, placed in the back of the number. Short row "-" behind the two digit number indicates that the welding electrode type, welding position and welding current type.
