Stainless steel electrode can be divided into chromium and chromium -nickel stainless steel welding electrodes, welding of these two who meet the national standard , according to GB GB/T983-1995 provides Copper Electrode assessment.Chromium- chromium (oxidizing acids , organic acids , cavitation ) heat and corrosion resistance . UsuallySelected as power plants, chemical , oil and other equipment and materials . But chromium stainless steel Generally poor weldability , should pay attention to the welding process, heat treatment conditions and the appropriate choice of welding .
