Welding is one of the main process for the manufacture of pressure vessels, while the electrode is the most commonly used welding auxiliary materials. Stainless Steel Electrode is a kind of electrode can be divided into chromium stainless steel welding rod and chrome-nickel stainless steel electrode.
Stainless Steel Electrode of deposited metal at room temperature, high or low temperatures, with varying degrees of resistance to atmospheric corrosion medium corrosion resistance and mechanical properties, were selected for power plants, chemical, oil and other equipment and materials. Poor weldability chromium stainless steel under normal circumstances, you should pay attention to the welding process, heat treatment conditions and the appropriate choice of welding.
Stainless steel electrode according to the chemical composition of deposited metal, drug skin types, welding position, welding current type of model, the letter "E" indicates the electrode, the "E" behind the numbers indicate the classification code of the deposited metal chemical composition, and any special requirements chemical composition, the chemical composition of the element symbols on the back of the figures. Dash "-" behind the two numbers indicate the electrode type, welding position and type of welding current.
