A062 line with GB E309L-16 
 Rather AWS E309L-16 

 Description: A062 is a titanium calcium type of ultra-low carbon stainless steel electrode Cr23Ni13 can be AC ??and DC, due to low carbon content, so the non-Nb, Ti and other stabilizers can resist when they arise due to precipitation of carbides intergranular corrosion. 


 Uses: used in synthetic fibers, petrochemicals and other equipment manufactured by the same type of stainless steel, composite steel and dissimilar steel and other components can also be used for nuclear reactor pressure vessel wall transition layer of surfacing and welding the tower components.
