Release date: May 28, 2020 Number of visits: four hundred

Stainless steel water tank J422 and stainless steel welding rod can be used.

The material of galvanized pipe is Q235 ordinary steel, stainless steel and ordinary steel are dissimilar steel, welding rod suitable for common steel should be selected.

J422 electrode is matched with Q235 steel. As a result, the cost is saved and the operation is easier than using stainless steel rod, and the welding strength is not affected. Considering from the above three aspects, the nickel content is 304. Good welding performance, tight welding and good performance. The characteristics of A302 stainless steel rod are consistent with AWS type GB e309-16 which is equivalent to GB e309-16

A302 is cr23ni13 stainless steel electrode with titanium calcium coating. The deposited metal has good crack resistance and oxidation resistance. It can be used for both AC and DC, with good operation and technical performance. In order to improve the crack resistance and corrosion resistance of the fused metal, the content of Mo should be increased moderately, which is about 1% higher than that in e309-16 of GB / t983-1995. Other components meet the national standard. Application: used for welding the same type of stainless steel, stainless steel lining, dissimilar steel (cr19ni9 and low carbon steel), high chromium steel, high manganese steel, etc.
