What wire is used for 316L stainless steel? Thanks
Use the standards of the National Metallurgical Department, YB/T5092-2005:H03Cr19Ni12Mo2SiGBT 29713-2013 stainless steel wire and welding strip: S316LAmerican national standard, AWS, A5.9:ER316LJapanese standard: SUSY316L
With the corresponding AWS A5.9 ER316L American Standard stainless steel wire
AWS A5.9 ER316LCorrosive environment, it is best to use GTAW rendering, SMAW cover surface. Welding materials: ER316L+A022Stainless steel electrode can be divided into chromium stainless steel electrode and chromium nickel stainless steel electrode, these two kinds of welding rod in accordance with national standards, according to the national standard GB/T983-1995 examination. Chromium stainless steel has certain corrosion resistance (oxidizing acid, organic acid, cavitation erosion), heat resistance and corrosion resistance. It is usually chosen as power station, chemical, petroleum and other equipment materials. But chromium stainless steel generally weldability is poor, should pay attention to welding process, heat treatment conditions and choose the appropriate welding rod. Chromium nickel stainless steel electrode has good corrosion resistance and oxidation resistance. It is widely used in chemical, chemical fertilizer, petroleum and medical machinery manufacturing. In order to prevent intergranular corrosion due to heating, the welding current should not be too large, less than 20% of the carbon steel electrode, the arc should not be too long, the inter layer is cold, and the narrow welding bead is suitable.
