E308-15 is a low carbon chrome19nickel10 stainless steel electrode with low hydrogen type coating..

Description:E308-15 is a low carbon chrome19nickel10 stainless steel electrode with low hydrogen type coating. The deposited mental has good mechanical properties and inter-crystalline corrosion resistant properties. It should be connected with negative polarity on DC and can be welded in all position.

Application:Used to weld the 0chrome 19nickel9 stainless steel structure which is anticorrosive and work under 300 degree centigrade, as well as some bad welding steel structure such as high chrome steel, and the surface of the pile welding stainless steel structure.CHEMICAL COMPOSITION OF MELTING METAL(%)
