Henan stainless steel electrode on profiling, is the first to analyze the classification of stainless steel rod, stainless steel electrodes can be divided into chromium and chromium-nickel stainless steel welding electrodes, welding of these two who meet the national standard, according to the national standard GB / T983 -1995 provides assessment. A martensitic stainless steel electrode: martensitic stainless steel including chromium containing from 5 to 9 percent of chromium steel and chromium 12% of high-chromium steel. Such steel hardening tendency of large, easy to produce high hardness after welding martensite and bainite increased brittleness, residual stress is large, prone to cold cracks. It must be carried out and the layer of insulation between the preheat before welding in general, not yet cooled after welding performed before tempering. 2, 13 chrome stainless steel welding: These chrome steel welded hardening large, prone to cracking, after the use of a similar chromium stainless steel electrode (CHK202, CHK207) welding, it must be more than 300 ℃ preheating and soldering 700 about tempering ℃ slow cooling treatment. If the weldment after welding can not be processed, the application of chromium stainless steel electrode (CHS107, CHS207), such as welding. 3, 17 chromium stainless steel welding: Such chrome steel is usually improved corrosion resistance and weldability and add an appropriate amount of stabilizing elements titanium, niobium, molybdenum, chromium 13 weldability than steel as well, may be of the same type Gang chromium stainless rod (CHK302, CHK307) welding. Before welding, weldment should be preheated to about 200 ℃, 800 ℃ tempered about after welding. May also be chrome-nickel stainless steel electrode (eg CHS107, CHS207), no heat treatment after welding. Zhengzhou Fung Shing Stainless Steel Co., Ltd.
