Description: A062 is an ultra-low carbon Cr23Ni13 stainless steel electrode with titanium-calcium coating. It can be used for both AC and DC. It has a low carbon content, so it can resist intergranular corrosion caused by carbide precipitation without stabilizers such as niobium and titanium. Application: It is used for the same type of stainless steel structure, composite steel, and special-shaped steel components in the manufacture of synthetic fiber, petrochemical, and other equipment. It can also be used for the surfacing of transition layers on the inner wall of nuclear reactor pressure vessels and the welding of tower internals.
