A402 stainless steel electrodes meet the GB E310-16 rather AWS E310-16 
 Description: A402 is a titanium calcium type of Cr26Ni21 pure austenitic stainless steel electrodes. Deposited metal 900 ~ 1100 ℃ high temperature conditions with excellent resistance to oxidation. AC and DC, good welding performance. 
 Uses: Used to work under high temperature conditions, the same type of heat-resistant stainless steel, can also be used for hardening of the large chrome steel (such as Cr5Mo, Cr9Mo, Cr13, Cr28, etc.) and dissimilar steels.
