Chromium-Nickel Stainless Steel Electrode

Chromium-nickel stainless steel electrode has good corrosion resistance and oxidation resistance, and it is widely used in the manufacture of chemical, fertilizer, petroleum, food, medical equipment and equipment.

Chromium-nickel stainless steel electrode has good corrosion resistance and oxidation resistance, and it is widely used in the manufacture of chemical, fertilizer, petroleum, food, medical equipment and equipment. In recent years, with the development of industry, there are more than 30 varieties of chromium-nickel stainless steel welding rods.

When welding, chromium-nickel stainless steel is subjected to repeated heating, and it is easy to precipitate carbides, so that the corrosion resistance and mechanical properties are reduced, therefore, the welding rod should be properly selected according to the working conditions of the equipment (working temperature and medium type, etc.) when welding, and the following matters should be paid attention to when using:

Ultra-Low-Carbon Stainless Steel Welding Electrode

1. There are usually three types of coating types for stainless steel electrodes: rutile type, titanic acid type and alkaline coating type. Among them, the stainless steel electrode of rutile and titanate coating type has shallow arc penetration of AC welding, which may cause defects such as non-fusion of the weld root, so DC welding is used as much as possible, and the stainless steel electrode of alkaline coating type has better crack resistance and is suitable for welding with large binding force.

2. In order to prevent intergranular corrosion caused by heating, the current should not be too large during welding, generally about 20% lower than that of carbon steel electrodes, and the arc should not be too long, and the interlayer is fast cooling, and narrow channel welding is appropriate.
