What is the difference between A302 stainless steel electrode and A402 stainless steel electrode?
A302 is Cr23Ni13 stainless steel electrode titanium calcium type coating for welding, the same type of stainless steel, lining stainless steels (Cr19Ni9 low carbon steel and high chromium steel and high manganese steel) etc.. A402 is Cr26Ni21 pure titanium calcium type austenitic stainless steel electrode coating, for the same type of heat-resistant stainless steel under high temperature welding, can also be used for large steel hardening (such as Cr 5 mo, Cr 9 mo, Cr 13, Cr 28) and welding of dissimilar steel.
One for 309SThe other one is used in 310S
A402 stainless steel welding rod can weld 304 stainless steel, but it is relatively wasteful. 304 stainless steel with A102, A107, A132, A137 and other stainless steel welding electrodes can be welded.A402 stainless steel electrode:A402 is Cr26Ni21 pure austenitic stainless steel electrode with titanium calcium coating, and has good welding performance.Use: for the same type of heat-resistant stainless steel under high temperature welding, can also be used for hardening of the large steel (such as Cr5Mo, Cr9Mo, Cr13, Cr28 etc.) and the welding of dissimilar steel.
