Description: A407 is a Cr26Ni21 pure austenitic stainless steel electrode with low hydrogen sodium coating. Use DCEP (direct current electrode positive) and can be welded in all positions. Deposited metal has good oxidation resistance under high temperature conditions of 900 ~ 1100 ℃. Since the deposited metal is pure austenite, the thermal crack resistance is not as good as that of the duplex structure. Application: It is used for welding the same type of heat-resistant stainless steel, stainless steel lining and dissimilar steel, and it can also be used for welding steel structures such as Cr5Mo, Cr9Mo, Cr13 and Cr28 with high hardenability.
