Stainless Steel Welding Electrode
A062
GB/T E309L-16
AWS E309L-16
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.

Notice:
1. The electrode must be baked for 1 hour at around 150℃ before welding operation;
2. Because the penetration depth is shallow during AC welding, the DC power supply should be used as much as possible to get deeper penetration. and the current should not be too large to avoid redness of the welding rod
